Subject: RE: [ubl-ndrsc] Bill&Eve's proposal on local/global elements
Folks: Mike Rawlins makes the comment that we should not "invent" new RTs, since then we won't be ebXML-compliant. While I appreciate what he is saying, i would like to point out sonme cases where the RTs we have been given are insufficient: (1) Duration - this is a primitive type in the XSD datatypes we are using, and it has a lot of business use. If, for example, I need to express a shelf life, then I need to express this as a suration, since I may not know when specific perishable goods will be delivered (the start date) or I may be using the duratiuon as a pure descriptior. (2) URL/URI/URN - while this is really just a type of address, it is a priviledged sort that is treated specially. Especially in the case of URLs, we will need to be able to identofy and resolve these. I would suggest that this needs to be an RT, although perhaps this is simply a matter of binding and can be left in that space. Common use of this is with attachments, which brings me to my next point... (3) "Graphic" as suggested by the CC spec is unworkable. You very rarely put graphics inline in business documents - typically, you specify what they are called from the computers' point of view (a URL - that is, a file name - pointing into your multipart MIME or whatever, and some descriptive text explaining what the purpose of the graphic is - a logo, a CAD image, etc. It is polite also to describe the format of the graphic.) (4) "Prose" - as Eve mentioned in our discussion of mixed content, this is a distinct type of content that is not common in business documents, but does need to be accomodated where it does occur. Perhaps we can submit these as comments to the CC spec, and get them fixed next week in Seattle. However, we need for our own purposes to get a workable system, and should not be too hampered by a specification that has not been widely implemented. It seems to me that we should be able to get our fedback into the CC group through common membership. Certainly, Mark, Gunther, and myself are active in the CC group, and I believe that we should be able to raise these points and get a positive response. Cheers, Arofan
