Paul Thorpe6/13/200211:05:17 AMWelcome Monica
Monica Martin6/13/200211:05:19 AMHello.
Phil Grifin6/13/200211:05:28 AMWe'll wait just a few minutes to get started. Monica Martin should be joining us as we just finished our first Security JC call.
Monica Martin6/13/200211:05:36 AMMonica here
Tyky Aichelen6/13/200211:05:37 AM8 of us
Phil Grifin6/13/200211:05:43 AMI trust that everyone has the input document?
Alessandro Triglia6/13/200211:05:48 AMYes
Tyky Aichelen6/13/200211:05:51 AMyes
John Larmouth6/13/200211:05:52 AMYup
Ed Day6/13/200211:05:52 AMyes
Paul Thorpe6/13/200211:05:54 AMYes
Monica Martin6/13/200211:06:06 AMYes
Paul Thorpe6/13/200211:06:18 AMWho would like to put it on the screen (share it)?
Phil Grifin6/13/200211:06:35 AMOK. Please look at the X9.84 and BioAPI 1.1 Interoperability section. And yes, Paul please put it on the screen
Paul Thorpe6/13/200211:06:41 AMDo we have a new agenda?
Phil Grifin6/13/200211:07:07 AMNo agenda other than what I posted with this document.
Paul Thorpe6/13/200211:07:55 AMI will create minutes starting with the minutes from the last meeting.
Phil Grifin6/13/200211:08:21 AMRight away, I'd like to ask Paul to please take minutes once again, and to post the meeting log as well.
Phil Grifin6/13/200211:09:12 AMThe section "X9.84 BiometricSyntax" is first and I'll ask if there are any major concerns here.
Paul Thorpe6/13/200211:09:27 AMI must have saved the input document to the wrong directory. Can someone else share it?
John Larmouth6/13/200211:10:30 AMOK. I will try to share.
Monica Martin6/13/200211:10:42 AMI selected share - what else is required for you to see it?
Alessandro Triglia6/13/200211:11:02 AMThe BioAPI Signature field must be ignored - Agreed
Phil Grifin6/13/200211:11:17 AMPaul, I've clicked on share for this file but I'm not sure how to tell if it's working.
Paul Thorpe6/13/200211:11:29 AMIt is working
Paul Thorpe6/13/200211:11:47 AMAs long as you don't have any windows in front of it, we can see it.
Paul Thorpe6/13/200211:12:03 AMWho currently is owner of the document?
John Larmouth6/13/200211:12:13 AMToo many of us sharing!
Monica Martin6/13/200211:12:24 AMI'll unshare.
Phil Grifin6/13/200211:12:36 AMI've unshared too
Paul Thorpe6/13/200211:12:45 AMPlease wait
Phil Grifin6/13/200211:12:51 AMJohn, have you got the doc
Paul Thorpe6/13/200211:12:53 AMwho is currently owner of the document?
John Larmouth6/13/200211:13:21 AMI've also unshared.
Paul Thorpe6/13/200211:13:21 AMWelcome Paul Gerome
John Larmouth6/13/200211:13:46 AMI suggest that ownership should be with the person sharing the file. They can then distribute an changed version.
Paul GEROME6/13/200211:13:54 AMPaul Gerome has joined now.
Paul Thorpe6/13/200211:14:03 AMThat means everyone has unshared.
Phil Grifin6/13/200211:14:21 AMI will try to share again so that I can make changes
Paul Thorpe6/13/200211:14:25 AMPlease select someone to "own" and "share" the document
Paul Thorpe6/13/200211:14:29 AMthanks phil
Alessandro Triglia6/13/200211:15:20 AMI am getting no shares
Monica Martin6/13/200211:15:32 AMDon't see the document. Anyone else?
Monica Martin6/13/200211:15:44 AMAha!
Paul Thorpe6/13/200211:15:55 AMPhile has some windows open over the document.
Alessandro Triglia6/13/200211:16:12 AMIs anyone getting someone else's shared document?
Monica Martin6/13/200211:16:32 AMGetting window and awaiting document.
John Larmouth6/13/200211:16:37 AMI am getting Phil's
Paul GEROME6/13/200211:17:06 AMI am getting it too
Phil Grifin6/13/200211:17:42 AMIt is the same doc sent yesterday. No changes. See X9.84 BiometricSyntax section
John Larmouth6/13/200211:18:02 AMMy main comment on the clause Phil mentioned is that (apart from the ASN,1) it is largely tutorial, but it is not clear what "corresponds closely to" means.
Phil Grifin6/13/200211:18:14 AMAny comments on this section? Note that just above that BioAPI has been approved as an ANSI standard.
Monica Martin6/13/200211:19:07 AMSuggest we provide itemized bullets for the different types of biometric information so it is clearly understood what they are.
Phil Grifin6/13/200211:19:08 AMJohn it is meant to mean "not equivalent" but close
John Larmouth6/13/200211:19:28 AMYes, but shouldn't we spell out the differences?
Phil Grifin6/13/200211:19:31 AMMM what do you mean, "types"
Phil Grifin6/13/200211:19:55 AMJL That is what each following section attempts to do
Monica Martin6/13/200211:19:58 AMJust that we should bullet out and provide a description of the four possible formats for biometric information.
John Larmouth6/13/200211:20:04 AMAnd what is the purpose of this clause? Are we putting it in in order to map X9.84 into the BioAPI BIR?
Phil Grifin6/13/200211:21:07 AMMM Agree text needed here or preceeding this section. But note that the other choices all use this BiometricObject
Monica Martin6/13/200211:21:18 AMUnderstood.
Phil Grifin6/13/200211:21:31 AMJL No, the idea is to map BIR to BiometricObject
Paul GEROME6/13/200211:21:36 AMUnterstood
John Larmouth6/13/200211:21:51 AMEither way, the purpose needs to be made clear.
Phil Grifin6/13/200211:22:29 AMMM Will you craft a paragraph describing each choic and end it with a line that we will discuss only the unprotected BiometricObject in this section.
John Larmouth6/13/200211:22:55 AMThe heading is simply X9.84, but the text refeferences BioAPI.
Monica Martin6/13/200211:22:57 AMI can craft as much as I have in the document, but may need some descriptors from you technical folks.
Phil Grifin6/13/200211:22:58 AMJL Agree. This is a start. Please after the meeting, submit text to me or to the list for discussion.
Phil Grifin6/13/200211:23:40 AMGeneral: How about let's agree right away that all comments will
John Larmouth6/13/200211:23:50 AMProvided this chat is output from the meeting, that is sufficient to minute my comments.
Phil Grifin6/13/200211:24:02 AMbe in the form of an edited version of my draft with edit changes shown
Phil Grifin6/13/200211:24:24 AMCan we move to section X9.84 BiometricObject?
Tyky Aichelen6/13/200211:24:38 AMMM, descriptors? Mapping means merging the 2 C code together?
John Larmouth6/13/200211:24:49 AMUse of Word COMMENT may be better, unless there is actual new text
Monica Martin6/13/200211:24:54 AMI have documented that I will provide a paragraph in this section that describes the different formats of biometric information. I may solicit input from the team on technical desriptions.
Phil Grifin6/13/200211:25:21 AMMM Great!
John Larmouth6/13/200211:25:28 AMPhil has a window over his shared window, I think.
John Larmouth6/13/200211:25:38 AMI am not getting the whole window
Paul Thorpe6/13/200211:25:43 AMPhil, Please move you chat window to the side more
Paul Thorpe6/13/200211:25:45 AMthanks
Phil Grifin6/13/200211:25:52 AMJonhn is that better?
John Larmouth6/13/200211:26:02 AMNot yet.
John Larmouth6/13/200211:26:11 AMAh! OK now
Phil Grifin6/13/200211:26:12 AMNow?
John Larmouth6/13/200211:26:20 AMJust went back again!
John Larmouth6/13/200211:26:34 AMWait a mo for things to sync
Paul Thorpe6/13/200211:26:49 AMGood
John Larmouth6/13/200211:26:50 AMOK now.
Phil Grifin6/13/200211:26:56 AMLet's look now then at "X9.84 BiometricObject"
John Larmouth6/13/200211:27:16 AMWe were. surely???
Phil Grifin6/13/200211:27:33 AMComments on this section?
Ed Day6/13/200211:27:53 AMCan nothing be done with signature? Some sort of default?
Paul GEROME6/13/200211:27:54 AMDefinition of object in this context requested?
Alessandro Triglia6/13/200211:28:39 AMNo, Ed. It's impossible to understand the content of the BioAPI Signature field
Phil Grifin6/13/200211:28:43 AMED We do not own signature in BIR and their standard says they may define a struct one day
Alessandro Triglia6/13/200211:29:06 AMBioAPI refused to standardize signatures
Monica Martin6/13/200211:29:13 AMCan we at least give a broad definition of an object as Paul G asked?
Ed Day6/13/200211:29:34 AMObject is simply a data record
Phil Grifin6/13/200211:29:45 AMJohn, want to tell us what an object is? You're the only one who speaks English ;-)
Monica Martin6/13/200211:29:53 AMAdd that definition.
John Larmouth6/13/200211:29:55 AMBut instead of ignoring it, can't we use it with some OID for an "unknown" algorithm etc?
Phil Grifin6/13/200211:30:26 AMOK Object is a "data record", a logical piece of biometric information?
John Larmouth6/13/200211:30:42 AMI really don't like that
John Larmouth6/13/200211:30:49 AMIt is too unspecific
Monica Martin6/13/200211:31:00 AMProvide context, John.
Paul GEROME6/13/200211:31:11 AMSo: a BIOMETRIC OBJECT is simply a data record taken from a bio source
Phil Grifin6/13/200211:31:16 AMJL "object" is meant to be unspecific in this context I think
John Larmouth6/13/200211:31:45 AMIf we look at what the X9.84 object actually is, it is a digitisation of one or more biometric properties and associated information
Phil Grifin6/13/200211:31:46 AMPG A biometric object may be either a template or a sample.
Monica Martin6/13/200211:32:15 AMHere is what I have so far: An object is a data record taken from a biometric source or a logical piece of biometric information. A biometric object may either be a template or a sample.
Paul GEROME6/13/200211:32:19 AMThanks, Phil!
Alessandro Triglia6/13/200211:32:24 AMNot only that
Tyky Aichelen6/13/200211:32:26 AMJL, Why not? it is a XML SOAP object which contain a unit of info readily manipulable by applications and transportable via Web
Phil Grifin6/13/200211:32:27 AMJL That is true. The header is really a set of associated attributes that belong with the opaque data
Alessandro Triglia6/13/200211:32:45 AMIt is .... plus additional information about the purpose, the quality, etc.
Monica Martin6/13/200211:33:23 AMNow...An object is a data record taken from a biometric source or a logical piece of biometric information. A biometric object may either be a template or a sample. The header is a set of associate attributes that belong with the opaque data, and can include additional information about the purpose, quality, etc.
John Larmouth6/13/200211:33:42 AMI think we need not define "object"
Monica Martin6/13/200211:34:01 AMWe should have a glossary or a reference.
John Larmouth6/13/200211:34:11 AMWhat we want is a definition of "biometric object" that fits the information content in the X9.84 BiometricObject type
Paul GEROME6/13/200211:34:16 AMFar out! I agree with MM
Phil Grifin6/13/200211:34:27 AMJL I think that we might elsewhere, say in a glossary
Phil Grifin6/13/200211:34:43 AMSo I should add a Glossary section?
Paul GEROME6/13/200211:34:58 AMOh, definitely!
John Larmouth6/13/200211:35:10 AMA definition of "biometric object" (rather than a glossary) is more important than a definition of "object"
Monica Martin6/13/200211:35:14 AMMay want to consider if it is a separate document, appendix or included in the specification.
Alessandro Triglia6/13/200211:35:24 AMAbsolutely agree with John
Phil Grifin6/13/200211:35:30 AMLet's agree that I will add a Glossary section and that Monica's suggested def will be its first entry
Phil Grifin6/13/200211:35:54 AMAT I do too. Biometric is key here.
John Larmouth6/13/200211:35:58 AMI think there are an awful lot of terms defined in X9.84, and this may be one of them,
Phil Grifin6/13/200211:36:07 AMJL Agree.
Monica Martin6/13/200211:36:17 AMHere is what I have so far.....An biometric object is a data record taken from a biometric source or a logical piece of biometric information. A biometric object may either be a template or a sample. The header is a set of associate attributes that belong with the opaque data, and can include additional information about the purpose, quality, etc. This must be in line with the information content in X9.84 BiometricObject type.
Monica Martin6/13/200211:36:36 AMWhittle away folks.
Phil Grifin6/13/200211:36:54 AMMM Let's start with that and whittle on the mailing list
Paul GEROME6/13/200211:37:01 AMPerfect as a first draft, thanks to all for superb efficiency!
Alessandro Triglia6/13/200211:37:03 AMNot just a sample, it may be a few samples
Monica Martin6/13/200211:37:07 AMOK
Paul GEROME6/13/200211:37:22 AMAT you are very right!
John Larmouth6/13/200211:37:23 AMThis definition introduces two new concepts: template and sample, which need definition. I really think that we should base things on importation (byr reference) of the X9.84 defintions
Paul GEROME6/13/200211:37:44 AMI agree
Ed Day6/13/200211:37:52 AMI would say "represents a template or samples" not "is a"
Phil Grifin6/13/200211:38:23 AMOK. Can we now look at the "X9.84 BiometricHeader" section?
John Larmouth6/13/200211:38:29 AMWe have moved a long way form the clause we were discussing
Monica Martin6/13/200211:38:33 AMA biometric object is a data record taken from a biometric source or a logical piece of biometric information. A biometric object may represent either a template or a sample(s). The header is a set of associate attributes that belong with the opaque data, and can include additional information about the purpose, quality, etc. This must be in line with the information content in X9.84 BiometricObject type.
Paul Thorpe6/13/200211:38:53 AMTyky has dropped out.
Paul GEROME6/13/200211:38:56 AMwhat about "STAND FOR", so it is compliant with the classic definition of a "sign" in Semiotic Studies
John Larmouth6/13/200211:39:00 AMAs an aside, can we please have clause and paragraph numbers on documents in the future? It makes discussion so much easier.
Monica Martin6/13/200211:39:21 AMWhere would you like STAND FOR, Paul G.
Paul GEROME6/13/200211:40:09 AMI was editing on ED "represent"
Monica Martin6/13/200211:40:18 AMOK.
John Larmouth6/13/200211:40:21 AMMonica, it appears you are keeping a record of proposed text? Would you like to share your application?
Monica Martin6/13/200211:40:41 AMI type faster than the screen refreshes.
Monica Martin6/13/200211:40:54 AMIf you wish, I can.
John Larmouth6/13/200211:41:01 AMIt is still useful to see the record.
Monica Martin6/13/200211:41:13 AMOK, Phil G unshare so I can share.
Phil Grifin6/13/200211:41:20 AMLet's finish this item. The def that MM has can be placed in a new glossary section for further discussion
John Larmouth6/13/200211:41:24 AMNO!
John Larmouth6/13/200211:41:38 AMI was not intending to be that disruptive. Surely two can share?
Paul Thorpe6/13/200211:41:49 AMThere is no need for Phil to unshare while you share.
Monica Martin6/13/200211:41:55 AMOK.
Paul Thorpe6/13/200211:42:53 AMYou just need to have the item you are sharing visible on your screen
Phil Grifin6/13/200211:42:54 AMAT Do you agree that I've cut and pasted the correct definitions for types and structures from BIR and X9.84 into this draft?
Alessandro Triglia6/13/200211:43:25 AMI agree
Alessandro Triglia6/13/200211:43:42 AMI noticed that you have made several changes to the ASN.1 modules
Phil Grifin6/13/200211:43:55 AMAT If you find ANY out of whack in the doc, please send me a note
Monica Martin6/13/200211:44:09 AMI shared and allowed control but don't know if anyone sees it.
Alessandro Triglia6/13/200211:44:14 AMOK
Paul Thorpe6/13/200211:44:21 AMNo need to allow control
Paul Thorpe6/13/200211:44:27 AMThat does not work well
Monica Martin6/13/200211:44:28 AMOK.
John Larmouth6/13/200211:44:34 AMI suggest it is better not to allow control
Phil Grifin6/13/200211:45:01 AMAT I've changed the modules as part of a revision of X9.84 that is now active in X9F4. I've posted the latest in this draft.
Monica Martin6/13/200211:45:04 AMRevised control.
John Larmouth6/13/200211:45:52 AMThe original X9.84 did not have an extensibility ellipsis.
John Larmouth6/13/200211:46:04 AMAre there any interworking issues between version 1 and 2?
Phil Grifin6/13/200211:46:48 AMJL ... where?
John Larmouth6/13/200211:47:09 AMWhere you added the PHG items
Alessandro Triglia6/13/200211:47:38 AMI am very happy with those changes
John Larmouth6/13/200211:48:39 AMI was not contesting the changes, just asking for clarification on whether version 1 had been implemented, and if interworking with version 2 was important.
Alessandro Triglia6/13/200211:48:56 AMWe are not aware of any current implementation of version 1
Monica Martin6/13/200211:49:00 AMPhil, what page and reference to PHG is under discussion?
John Larmouth6/13/200211:49:26 AMReply to AT: End of problem
Phil Grifin6/13/200211:49:55 AMMM In the ASN.1 where I added new biometric types and a few other changes.
John Larmouth6/13/200211:50:04 AMBut we need to get extensibility markers into this new version.
Phil Grifin6/13/200211:50:11 AMOK X9.84 BiometricHeader section
Phil Grifin6/13/200211:50:51 AMJL Make suggestions to the list on any extension markers you would propose. I can get them in now that I've got a revision process approved.
John Larmouth6/13/200211:50:54 AMRoll your screen up, Phil
John Larmouth6/13/200211:51:39 AMPositioning of extension markers needs serious subject knowledge and discussion. Of course, we could try for EXTENSIBLE EVERYWHERE
Phil Grifin6/13/200211:52:34 AMMy text in this section at the end especially is weak
Ed Day6/13/200211:52:37 AMwhat purpose do they serve for XER or DER encoding?
John Larmouth6/13/200211:53:14 AMExtensibility markers affect the behaviour of version 1 systems, not just the encodings.
John Larmouth6/13/200211:53:33 AMIt is a question of ignoring added material or diagnosing an error.
John Larmouth6/13/200211:53:49 AMFor security reasons, it is best to be specifi on when stuff should be ignored.
Phil Grifin6/13/200211:53:52 AMJohn. Please discuss extension markers on the mailing list, not on net meeting.
Phil Grifin6/13/200211:54:14 AMPlease look at the X9.84 BiometricHeader section
Phil Grifin6/13/200211:55:22 AMAny comments on this section? the BIR or the ASN.1 OK?
Paul Thorpe6/13/200211:55:31 AMPhil Please roll your screen up and back down to refesh the display.
Paul Thorpe6/13/200211:55:54 AMthanks
Alessandro Triglia6/13/200211:56:17 AMThey seem to be OK, but I cannot do a comparison with the BioAPI spec right now
Monica Martin6/13/200211:56:48 AMThe hour is almost up.
Phil Grifin6/13/200211:57:04 AMQuickly then, on to DataType
Ed Day6/13/200211:57:05 AMAre X9-84 types that are used open to debate or is this just a discussion of existing BioAPI -> X9.84?
John Larmouth6/13/200211:57:06 AMI am very unclear what is the purpose of this text.
John Larmouth6/13/200211:57:43 AMAre we trying to justify that the X9.84 format is the better of the two? Or are we simply doing an impartial comparison, or what?
Phil Grifin6/13/200211:58:01 AMEd, the type definitions are far easier to modify in a revised standard than to change the type.
John Larmouth6/13/200211:58:17 AMThe BIR effectively contains length determinants explicitly (as is normal in bits and bytes protocols).
John Larmouth6/13/200211:58:29 AMThat is not an error. Just a different way of presenting things.
Phil Grifin6/13/200211:58:37 AMJL Please suggest any replacement text.
Phil Grifin6/13/200211:59:00 AMJL The signature field is not presented in the length.
Phil Grifin6/13/200211:59:25 AMJL this makes concatenation of BIRs in a stream difficult
John Larmouth6/13/200211:59:34 AMPG: That is not an issue - see my earlier ASN.1 for the BIR.
Paul Thorpe6/13/200211:59:50 AMTyky has rejoined
John Larmouth6/13/200212:00:04 PMWrappers can always be put round anything.
Phil Grifin6/13/200212:00:04 PMCan we look quickly at DataType
Paul Thorpe6/13/200212:00:18 PMHi Phil,
Paul Thorpe6/13/200212:00:29 PMWas this to be a 1 or 2 hr meeting?
John Larmouth6/13/200212:00:35 PMIf you want to concatenate binary encodings that are not self-delimiting, of course you need wrappers.
Phil Grifin6/13/200212:00:39 PMNotice that the encrypted and signed flags are not mapped to X9.84
Phil Grifin6/13/200212:01:10 PMPaul, I thought that it was to be 2 hours.
Paul Thorpe6/13/200212:01:27 PMOk. That is what I thought also.
John Larmouth6/13/200212:01:33 PMI see no reason to include the enumeration values in the ASN.1. It just adds confusion.
Phil Grifin6/13/200212:01:38 PMDataType folks?
John Larmouth6/13/200212:01:49 PMDelete the (0) etc
Phil Grifin6/13/200212:02:02 PMJL you mean in the table?
John Larmouth6/13/200212:02:07 PMAnd add an extension marker?
John Larmouth6/13/200212:02:27 PMYes, I think add the extension marker.
Alessandro Triglia6/13/200212:02:36 PMI don't think it is useful
John Larmouth6/13/200212:02:46 PMI mean in the ASN.1 that is on your screen.
John Larmouth6/13/200212:03:16 PMI could envisage a "final" in a future version.
Alessandro Triglia6/13/200212:03:33 PMA template is Processed
Alessandro Triglia6/13/200212:03:53 PMThere is no further state beyond the state of a template
John Larmouth6/13/200212:04:18 PMI think there could well be a further state in the future
John Larmouth6/13/200212:04:26 PMSuch as COMPRESSED.
Alessandro Triglia6/13/200212:04:31 PMBy the way, I would prefer "state" to "data type"
John Larmouth6/13/200212:04:37 PMOr even validated, or whatever.
Phil Grifin6/13/200212:04:38 PMJL You mean to drop the values in the type definition? Absolutely not. Explicit is always best. And I agree AT's argument. There are no other possible states for a record to have.
Paul GEROME6/13/200212:04:54 PMTo MM, on the old topic discussed earlier, when you requested tech support , I'll be pleased to input, when able
Alessandro Triglia6/13/200212:05:05 PMPhil, what about State?
Phil Grifin6/13/200212:05:13 PMAT Me too, but the goal when this was written was to use BIR language
John Larmouth6/13/200212:05:18 PMHa! I totally disagree with both those points, but move on if no-one else agrees.
Alessandro Triglia6/13/200212:05:27 PMIt has moved away already
John Larmouth6/13/200212:05:33 PMWhy put the values in when they are of no interest at the abstract level?
Phil Grifin6/13/200212:06:06 PMJL Programmers like to see as much information as possible.
John Larmouth6/13/200212:06:31 PMI have forgotten what the XER encoding is: the numbers or the names?
Alessandro Triglia6/13/200212:06:38 PMNAMES
Ed Day6/13/200212:06:47 PMIt is names with < /> around them
John Larmouth6/13/200212:06:55 PMIn which case the numbers should CERTAINLU be removed.
John Larmouth6/13/200212:07:23 PMPhil is thinking DER. We are doing XER here.
Phil Grifin6/13/200212:07:24 PMJL In DER it is the numbers, not the names.
Ed Day6/13/200212:07:38 PMI would agree. Programmers are used to enums without numbers unless needed for an out-of-order sequence.
John Larmouth6/13/200212:07:42 PMYes, but we are doing XER.
John Larmouth6/13/200212:08:03 PMAnd the numbers are defaulted anyway to the values you giv e
Tyky Aichelen6/13/200212:08:11 PMRe Programmers, I agree w/ Phil., a lot of more info is needed
Phil Grifin6/13/200212:08:11 PMJL X9.84 does DER
John Larmouth6/13/200212:08:13 PMKeep it simple!
Phil Grifin6/13/200212:08:33 PMJL Agree, simple. Explicit is simple.
John Larmouth6/13/200212:08:39 PMThe numbers are not needed for DER
John Larmouth6/13/200212:09:00 PMNo. The numbers are an encoding issue, and add confusion at the abstract level.
Phil Grifin6/13/200212:09:19 PMJL, please argue this on the list
John Larmouth6/13/200212:09:26 PMWe have to agree to disagree again.
Phil Grifin6/13/200212:10:00 PMJL. I'd value arguing this on the list. I consider it only a style issue.
John Larmouth6/13/200212:10:22 PMDrop it for now
Phil Grifin6/13/200212:10:23 PMPurpose section?
Alessandro Triglia6/13/200212:10:37 PMPhil, do you want to rename DataType to DataState?
Ed Day6/13/200212:10:44 PMwhy can't the numbers match?
John Larmouth6/13/200212:10:47 PMAgain, I want an extensibility marker.
Alessandro Triglia6/13/200212:10:48 PMI cannot digest DataType
John Larmouth6/13/200212:11:26 PMIndeed, what do the numbers actually MEAN?
Tyky Aichelen6/13/200212:11:33 PMI agree with AT , State is more pertinent here
John Larmouth6/13/200212:11:35 PMGet rid of them form the ASN.1!
John Larmouth6/13/200212:12:23 PMWhat are we discussing? I think it is not on Phil's screen
Phil Grifin6/13/200212:12:28 PMAT Argue for it on the list. I think "data type" is just about up there with "object". But I doubt that X9F4 will accept such a change, since the text "data type" is used in BioAPI.
Phil Grifin6/13/200212:12:56 PMPurpose
Ed Day6/13/200212:13:20 PMMy Q was in regards to Purpose. BioAPI and X.984 numbers don't match.
John Larmouth6/13/200212:13:20 PMAre we trying to edit an X9.84 document, or an OASIS one?
Phil Grifin6/13/200212:13:53 PMJL We are trying to base an OASIS standard on two ANSI standards that we do not own.
John Larmouth6/13/200212:13:55 PMWhat X9.84 might or migh tno accept is surely not relevant?
John Larmouth6/13/200212:14:41 PMI agree with Ed - all else aside, the numbers need to be aligned. This is a typo.
Phil Grifin6/13/200212:14:56 PMBoth ANSI standards will likely be proposed as and become ISO standards
Phil Grifin6/13/200212:15:04 PMAT Agree with Ed?
John Larmouth6/13/200212:15:06 PMOr is it a difference between the X9.84 encoding and the BioAPI?
Alessandro Triglia6/13/200212:15:09 PMPhil: When you added "enroll" upon my suggestion, we agreed to added it to the end
Paul Thorpe6/13/200212:15:12 PM"enroll": by its self is missing from the enumerated type.
Phil Grifin6/13/200212:15:43 PMPT Wuh?
Ed Day6/13/200212:15:48 PMI think you have the wrong doc. It is number 6 on mine.
Alessandro Triglia6/13/200212:15:52 PM.....But since we are making changes to the document, it is no longer necessary that it go to the end
John Larmouth6/13/200212:16:07 PMIf we have already added some enumerations, that strenghtens my argument for omiting numbers and adding an extensiblity marker.
Phil Grifin6/13/200212:16:31 PMAT Agree. Under a revision, if this group agrees I can add this in order and eliminate some confusion for all time. Agree?
John Larmouth6/13/200212:16:32 PMDo we have to be compatible with the earlier version?
Paul Thorpe6/13/200212:16:34 PMTyky has dropped out again.
Alessandro Triglia6/13/200212:16:39 PMYes Phil
Alessandro Triglia6/13/200212:17:02 PMJL, when "enroll" was added, there was such a need
John Larmouth6/13/200212:17:28 PMOther things will surely get added.
Alessandro Triglia6/13/200212:17:39 PMNow it is no longer necessary
John Larmouth6/13/200212:17:54 PMYou have to be joking!
Paul GEROME6/13/200212:18:02 PMI agree with John
John Larmouth6/13/200212:18:06 PMIf things are changed once, they will change again.
Paul Thorpe6/13/200212:18:19 PMAdd ... to the enumerated?
John Larmouth6/13/200212:18:24 PMBut let's m,ove on
Alessandro Triglia6/13/200212:18:33 PMHold!!! I was saying that it is no longer necessary that ENROLL goes to the end!
John Larmouth6/13/200212:18:42 PMPT: For me, yes#
John Larmouth6/13/200212:19:00 PMAh! I misunderstood you - sorry!
Phil Grifin6/13/200212:19:03 PMAT? Add the extension marker to this one?
Alessandro Triglia6/13/200212:19:10 PMI suggest we do
Paul Thorpe6/13/200212:19:32 PMTyky has rejoined.
John Larmouth6/13/200212:19:54 PMIf you are adding comment ...
Phil Grifin6/13/200212:20:11 PMAT OK now?
John Larmouth6/13/200212:20:18 PM... we ought somewhere sometime to indicate what a version 1 implementation should do with an added enumeration.
John Larmouth6/13/200212:20:33 PMProbably some sort of error return.
Paul Thorpe6/13/200212:20:40 PMPhill, Please roll up and back down to refresh the screen
Phil Grifin6/13/200212:20:48 PMJL Only AT and I have implementations to the best of all knowlege
Paul Thorpe6/13/200212:20:50 PMMuch better.
John Larmouth6/13/200212:21:25 PMWhat does your implementation do if given an enumeration outside the listed set?
Alessandro Triglia6/13/200212:21:43 PMThere is a typo: enrollIdentity instead of identify
John Larmouth6/13/200212:21:53 PMSorry - ignore that comment - without the extensibility marker it is just a duff encoding/
Phil Grifin6/13/200212:22:10 PMJL It throws an error right now. It will have to do otherwise
John Larmouth6/13/200212:22:28 PMNow we have added the extensibility marker, that is so.
John Larmouth6/13/200212:22:51 PMHas Monica recorded that we need to specify version 1 behaviour at some stage?
John Larmouth6/13/200212:23:05 PMHer screen has gone garbaged
Phil Grifin6/13/200212:23:14 PMMM may have dropped out She had a meeting
Paul Thorpe6/13/200212:23:27 PMShe is looking at Phil's screen (or was).
Phil Grifin6/13/200212:23:54 PMQuality?
Monica Martin6/13/200212:24:08 PMI am here for a few more minutes and refreshed my screen.
Alessandro Triglia6/13/200212:24:17 PMPhil, you still have IDENTITY instead of IDENTIFY in several places
Paul Thorpe6/13/200212:24:47 PMPhil, you made the wrong change. should by identify, not identity
Monica Martin6/13/200212:25:36 PMI have specified that at some point we need to specify version 1 behavior, John L.
Phil Grifin6/13/200212:25:41 PMLook now. Correct? If not BIR wrong?
John Larmouth6/13/200212:25:50 PMThanks MM - I saw it.
Alessandro Triglia6/13/200212:26:05 PMStill wrong, Phil, in the ASN.1
Phil Grifin6/13/200212:26:24 PMhere?
Alessandro Triglia6/13/200212:26:27 PMYes
Phil Grifin6/13/200212:26:49 PMOK?
Paul Thorpe6/13/200212:27:00 PMIn column 1 of the table also
Alessandro Triglia6/13/200212:27:04 PMI think it is still wrong in the table below
Tyky Aichelen6/13/200212:27:20 PMIt seems we are working with 2 standards with different fields or values sometimes. How about combine them both into the OASIS one, so nothing got left out
Alessandro Triglia6/13/200212:27:44 PMOK
Monica Martin6/13/200212:28:15 PMI have to drop off in five minutes, and I will send my notes to Phil for use/integration/etc. Thanks everyone. Monica
John Larmouth6/13/200212:28:20 PMTA: I agree
John Larmouth6/13/200212:28:34 PMWe need to consider what we are trying to do.
John Larmouth6/13/200212:28:47 PMAny semantics in either needs to be in our result
Alessandro Triglia6/13/200212:28:48 PMWhat do you mean by combine, Tyky?
John Larmouth6/13/200212:29:04 PMBut I believe that semantically, X9.84 has everything BIR has
John Larmouth6/13/200212:29:36 PMThe problem comes when the encoding (which is what BIR is about) has things in a different order from X9.84.
Alessandro Triglia6/13/200212:29:37 PMEverything except the multiple factors, but this will be solved
Tyky Aichelen6/13/200212:29:46 PMCombine means have a superset
Phil Grifin6/13/200212:29:49 PMJL I hope that you will urge the UK to call for an alignment of these two ISO standards.
John Larmouth6/13/200212:30:08 PMWhat ISO standards?
John Larmouth6/13/200212:30:27 PMAs far as I am aware, both BioAPI and X9.84 are purely US
Phil Grifin6/13/200212:30:40 PMJL Both BioAPI and X9.84 will likely be proposed to ISO
Paul GEROME6/13/200212:30:43 PMTyky, I like the definition
Phil Grifin6/13/200212:31:01 PMQuality?
John Larmouth6/13/200212:31:05 PMTo the same, or to different SC/TC
John Larmouth6/13/200212:31:06 PMs?
Tyky Aichelen6/13/200212:31:12 PMif OASIS standards contain everything any Standard out there in the world need. That would be great.
Phil Grifin6/13/200212:31:43 PMJL Not sure yet. The new SC has been approved in JTC 1 for generic biometrics, but they are not to do security
John Larmouth6/13/200212:31:46 PMThe last thing the world wants is three non-interworking standards with very similar functionality.
Alessandro Triglia6/13/200212:31:53 PMBy the way, are you all aware that ISO has established SC 37 on Biometrics?
Alessandro Triglia6/13/200212:32:07 PMJTC1 SC37
Phil Grifin6/13/200212:32:18 PMJL That is why X9.84 is being revised and wishes to incorporate the XER from this group.
John Larmouth6/13/200212:32:29 PMAre any of us likely to get involved in the work of that SC?
Paul GEROME6/13/200212:32:50 PMMay we liaise with them?
Phil Grifin6/13/200212:32:50 PMJL I'll likley be a liaison
Phil Grifin6/13/200212:33:10 PMPaulG We may try to do so.
Paul GEROME6/13/200212:33:10 PMPhenomenal!
John Larmouth6/13/200212:33:24 PMI suspect I could become a UK rep to that SC, with BSI funding for attendance ...
Alessandro Triglia6/13/200212:33:41 PMGood John
Phil Grifin6/13/200212:33:42 PMJL That woulfd be cool.
Monica Martin6/13/200212:33:54 PMHave to exit. Monia
Tyky Aichelen6/13/200212:34:00 PMJL, to not have 3 non-interoperable standards means we need a superset one, that is from OASIS.
Alessandro Triglia6/13/200212:34:01 PMBye Monica
Paul Thorpe6/13/200212:34:02 PMbye monick
John Larmouth6/13/200212:34:08 PMIt would be travel only, and I have my time cut out on ASN.,1 stuff!
Phil Grifin6/13/200212:34:10 PMJL They are just forming now and I do not believe that their mission is settled
John Larmouth6/13/200212:34:37 PMLet's discuss this off-line. I will put soundings out in BSI.
Phil Grifin6/13/200212:34:53 PMJL I'll send you the announcement of the SC.
Phil Grifin6/13/200212:34:58 PMQuality?
John Larmouth6/13/200212:35:02 PMDoes anyone know when the first meeting of the SC is?
Phil Grifin6/13/200212:35:13 PMJL Not set yet
Paul GEROME6/13/200212:35:18 PMIrequest from Phil the info to be sent to me too if possible
John Larmouth6/13/200212:35:24 PMOK. Quality?
Phil Grifin6/13/200212:35:47 PMPaulG I'll send what I know to the XCBF list on the new SC
Paul GEROME6/13/200212:36:02 PMthanks, Phil
Phil Grifin6/13/200212:36:40 PMQuality comments?
Paul GEROME6/13/200212:36:44 PMI'll inquire here in ISo main office in Geneva, as it is my base
Alessandro Triglia6/13/200212:37:09 PMExtension marker here
John Larmouth6/13/200212:37:18 PMI think not!
Alessandro Triglia6/13/200212:37:23 PMNO!!!!
Alessandro Triglia6/13/200212:37:25 PMRight
John Larmouth6/13/200212:37:28 PMDo we really want an extension marker?
Alessandro Triglia6/13/200212:37:40 PMIt is an integer
John Larmouth6/13/200212:37:41 PMI would prefer a subtype constraint -2..100
John Larmouth6/13/200212:37:55 PMNo extension marlker
Paul Thorpe6/13/200212:38:00 PMIt is there if Phil refereshes the screen.
Tyky Aichelen6/13/200212:38:07 PMRe Quality, we can combine all fields
Alessandro Triglia6/13/200212:38:12 PMBut actually........
Phil Grifin6/13/200212:38:27 PMActually, other values may be added.
Ed Day6/13/200212:38:31 PMI would say named numbers or range, but not both
Alessandro Triglia6/13/200212:38:31 PMWhy is there an unconstrained INTEGER there?
Paul Thorpe6/13/200212:38:58 PMPhil, please page up and down to refresh the screen.
Tyky Aichelen6/13/200212:39:01 PMName numbers, that way more can be added in futures
Paul Thorpe6/13/200212:39:31 PMthanks
John Larmouth6/13/200212:39:33 PMTA: No, I thik the whole idea is a range form 0 to 100
Ed Day6/13/200212:40:05 PMwhat about -1 and -2 ?
Tyky Aichelen6/13/200212:40:25 PMJL Range won't work with INTEGER
Alessandro Triglia6/13/200212:40:40 PMHold everybody
John Larmouth6/13/200212:40:42 PMHm. We need to specify that version 1 should treat values above 100 as simply higher values. In other words, positive values have integer semantics, even if extensions.
Tyky Aichelen6/13/200212:40:43 PM-1 -2 are signed INTEGER
Alessandro Triglia6/13/200212:40:59 PMThis is the original definition, and it is OK, there has always been an entension marker
John Larmouth6/13/200212:41:21 PMAT: I'll go along with that.
John Larmouth6/13/200212:42:00 PMWe just need text that version 1 systems should accept extensions and treat them as numerically higher quality for any comparisons that they do.
Phil Grifin6/13/200212:42:00 PMAT The extension marker was added after two BioAPI changes. One added -2, the other extended the range from 50 to 100 for highest. The marker was added defensively.
John Larmouth6/13/200212:42:30 PMYes. That is good
Alessandro Triglia6/13/200212:42:36 PMYes, Phil. Your screen was garbled before, and the line with the constraint was not visible
Alessandro Triglia6/13/200212:42:45 PMCuriously
Phil Grifin6/13/200212:42:51 PMAT Looked fine here ...
John Larmouth6/13/200212:43:04 PMBut I think we might want to say that an extension to -3 should give an error response, whereas extensions above 100 always meen higher quality.
Phil Grifin6/13/200212:43:30 PMAh! Record type
Phil Grifin6/13/200212:43:55 PMJL Not sure I agree about >100 being OK.
Phil Grifin6/13/200212:44:23 PMJL I was thinking that the next changes likely to occur would be made using negative values
John Larmouth6/13/200212:44:42 PMPG: What other action would you like a version 1 system to take?
John Larmouth6/13/200212:45:01 PMAny "special" additions can be made at -3, -4, etc.
Phil Grifin6/13/200212:45:14 PMJL Agree
John Larmouth6/13/200212:45:32 PMBut my point is simply that we need to specofy the version 1 actions. We do not need to agree them today!
Phil Grifin6/13/200212:45:59 PMJL OK
John Larmouth6/13/200212:46:15 PMMove on?
Phil Grifin6/13/200212:46:38 PMAll. I regret that I must leave this meeting early. Personal family matter.
Ed Day6/13/200212:46:58 PMRecordType - why not an enum or integer? this seems very complicated..
Paul Thorpe6/13/200212:47:30 PMAnything to minute before we end?
Phil Grifin6/13/200212:47:30 PMSoory for this. Let's discuss the points raised on the mailing list and try to progress them. When I return home, I'll post this revised document to the list.
Paul Thorpe6/13/200212:47:48 PMPhil, before you go, anything we need to minute?
Phil Grifin6/13/200212:47:55 PMPlease minute John's remark about specifying behavior of v1
Paul Thorpe6/13/200212:48:01 PMAll I have now is the attendees.
Phil Grifin6/13/200212:48:24 PMPlease minute that we will add a glossary of terms
John Larmouth6/13/200212:48:37 PMI think that posting the CHAT - not as a document, but as ASCII text - in an e-maiol would be useful, to help us to comment on it.
Phil Grifin6/13/200212:48:52 PMPlease minute that many items will be discussed on the mailing list
Phil Grifin6/13/200212:49:13 PMJL Good idea. Paul, please do.
Phil Grifin6/13/200212:49:19 PMBye
Paul Thorpe6/13/200212:49:30 PMWhat was John's item for the minutes?
John Larmouth6/13/200212:50:05 PMJust that the CHAT should be sent as a text e-mail, to make commenting on it easier, not as a document.
John Larmouth6/13/200212:51:12 PMAs we have a few minutes left (and in the absence of our chairman!) ...
Paul Thorpe6/13/200212:51:14 PMI will try, but am not sure of the format
John Larmouth6/13/200212:51:23 PM... is the broad purpose of this document to
John Larmouth6/13/200212:51:39 PMa) describe the differences between BIR and X9/84
John Larmouth6/13/200212:52:07 PMand b) to reco9mmend an ASN.1 format that reconciles the two as best we can/
John Larmouth6/13/200212:52:11 PMYes?
John Larmouth6/13/200212:52:36 PMIf so, then editing of the documnet becomes possible.
Alessandro Triglia6/13/200212:53:08 PMThe rest of the document gives the rules for the translation
Alessandro Triglia6/13/200212:53:18 PMIn both directions
John Larmouth6/13/200212:53:25 PMNo.
John Larmouth6/13/200212:53:29 PMNot in both directions
John Larmouth6/13/200212:53:44 PMFrom BioAPI and form X9 INTO our format
Paul Thorpe6/13/200212:53:53 PMAnything else for the minutes?
Ed Day6/13/200212:53:59 PMhe has sections describing both dirs
John Larmouth6/13/200212:54:00 PMOr maybe in all four directions?
John Larmouth6/13/200212:54:15 PMI guess we might recommend extensions to the BioAPI?
Alessandro Triglia6/13/200212:54:34 PMFour?
John Larmouth6/13/200212:54:35 PMExtensions to X9 seem to be in our dictat
John Larmouth6/13/200212:54:55 PMBioAPI to us, X9 to us, and the reverse of these equals four
John Larmouth6/13/200212:55:35 PMThis is Tyki's superset.
Alessandro Triglia6/13/200212:56:14 PMI believe Phil just wants to update X9.84 to make conversions easier
John Larmouth6/13/200212:56:25 PMSo .....
John Larmouth6/13/200212:56:38 PM.... what is the purpose of our document?
Alessandro Triglia6/13/200212:56:39 PMThe same updated X9.84 will be proposed to X9 and there will be just one new X9.84, revised
Alessandro Triglia6/13/200212:56:53 PMThere won't be a third document
John Larmouth6/13/200212:57:01 PMAre we merely helping Phil provid the next draft of X9?
Alessandro Triglia6/13/200212:57:06 PMThe old X9.84 will die
John Larmouth6/13/200212:57:15 PMSo ....
Alessandro Triglia6/13/200212:57:19 PMIt seems so
John Larmouth6/13/200212:57:24 PM... why are we referring to it in our document?
Alessandro Triglia6/13/200212:58:24 PMThe current X9.84 will be abandoned as soon as the revised version will be ready
John Larmouth6/13/200212:58:28 PMI would prefer it if we assumed a (non-existant) X9.84 revised, and then worked on our own document comparing that with BIR, and suggesting our own document and the mappings.
Alessandro Triglia6/13/200212:59:07 PMWhat we are doing is revising X9.84
John Larmouth6/13/200212:59:11 PMFor example, I think Phil will want numbers in enumerated in X9 revised. I would like them out in our document. But that does not affect interworking
Paul Thorpe6/13/200212:59:26 PMPlease note that the next meeting is scheduled for June 28. Our time is up.
John Larmouth6/13/200212:59:38 PMAlessandro, if that is all we are doing, we are spending a lot of unnecessary time going about it.
Paul GEROME6/13/200212:59:40 PMAT, I hope we will do more than just that revision
Alessandro Triglia6/13/200212:59:58 PMWe will do more
John Larmouth6/13/200213:00:09 PMThen we need a clear initial target.
Alessandro Triglia6/13/200213:00:22 PMBut the first step is updating X9.84 so that it is aligned with the BIR
John Larmouth6/13/200213:00:45 PMMaybe an initial step to agree and recommend revisions to X9 to update it and make it more compatible with BIR would be good
John Larmouth6/13/200213:00:52 PMBut that should be an explicit first goal
Paul GEROME6/13/200213:00:56 PMOPTIMAL SECURITY THROUGH TELEBIOMETRY: example for a target
John Larmouth6/13/200213:01:31 PMPG: Yes, we have lost sight of the security thread in recent CHAT
John Larmouth6/13/200213:02:03 PMAnyway, with no chairman, I guess someone should suggest that the meeting ends!
Paul GEROME6/13/200213:02:08 PMVOLUNTARY SELF-AUTHENTICATION is the PR motto
Alessandro Triglia6/13/200213:02:26 PMI heard Paul saying that
Paul GEROME6/13/200213:02:32 PMfor the new standard from oasis
Alessandro Triglia6/13/200213:02:45 PMI mean Paul T
