Subject: [uddi-spec-comment] W3C XML Schema for XTM DTD (Needed for UDDIefforts?)


This mail began with a request to topicmaps-comment from Max Voskob. I 
would like to know from UDDI committee if you require a W3C XML 
Schema  of  XTM.dtd for you work. If so, I can look into getting a 
standard, public version published. Please see exchange below.

*Max Voskob
During the last UDDI meeting we discussed an option of using external 
representation of taxonomies (it's a UDDI thing) and someone suggested to 
look into XTM. This is the primary reason for me to contact you and seek 
your cooperation.
  Personally, I think that XTM is a good standard, but I wish I had a 
schema for it! :)

I do have an xtm.xsd and it works in XML Spy. I am experimenting with 
creating a schema against an already produced topic map (define datatypes, 
limit the topics allowed, etc.)

Same here, except for the.NET part :)

If the applications were conforming to the same standards themselves that is :)

Which schema and which standard are you referring to, the W3C XML schema 
Are you referring to the XTM1.dtd, or your own W3C xml Schema which you 
generated from this DTD?
So did you finally succeed?

What I created is something I worked on last year and it is not production 
ready. I guess it would be a good idea to have an "official" W3C xml schema 
version  of the XTM.dtd available for public use.

I think that what I did could be reviewed by Martin Bryan, Henry 
Thompson  and others and submitted to ISO as a W3C schema version of 
XTM.dtd. If this is what you want, I can do that. When it is ready, you 
could both test these in your environments before it is released to the 
public. If this would be useful to the UDDI efforts, let's do it!
