I think it has been a common practice to use URIs or URLs as versioning mechanisms but I'm not it's the best practice. Let me give you an example: FOAF. FOAF a namespace but they are often adding new properties that people agree to be useful just like microformats. The URL is an identifier of a concept, but shouldn't be thought of it as a version or that its contents will never change.
In general I think that versioning is such a complicated beast and that it's hard to solve. Mark Baker recently talked about the issue: http://www.coactus.com/blog/2006/12/validation-considered-harmful/ However, I think that having disambiguation of properties or concepts is a good start but need not to be confused with versioning. -Elias On 12/13/06, Chris Messina <[EMAIL PROTECTED]> wrote:
This is a useful reply and seems relevant to authors/implementors and to parsers (though parsing doesn't belong on this list). If it's not been done already, could this be added to the wiki under versioning practices?
