<- I would second the approach that the metadata needs to live in-line in <- the document. If we claim that magic happens and out scrapes your nice <- metadata we are slipping backing into not having a way to do this. With <- autogeneration (CGI/servlet) of metadata, you have a whole new set of <- problems (e.g., if it is static then it can be out of sync, if it is <- automatic there is sometimes you needed to say this one doesn't need <- generating). Not to mention the storage of data that is already marked <- up (say the abstact, or subject headings), should I cache or shouldn't I <- cache. There are definite advantages (previously described) in having the metadata in-line. I do however think that having a generally agreed way of linking in metadata would be very worthwhile as a stopgap until the RDF in XHTML is resolved, *and* will be very useful to use in concert with inline metadata. The CGI generation of metadata is good idea, but talking about it at this stage might be counter-productive - it makes things appear more complicated than they need to be. Ok, let's say you want to provide metadata for the material online at w3.org. Say 1000 pages? Take this chunk - author:TimBL, publisher:w3.org, subject:semweb. That applies to 100 pages - 1 link to this metadata, it's possible that most of these pages contain enough additional metadata (title & meta tags) to distinguish them usefully. In other words, let's have some cascading metadata. On another line, forget XHTML for a moment, how do we embed metadata in other XML markups? <- And I like the test that you should be able to add it with vi (err let's <- say emacs). Your 'template' metadata is linked in, with vi you only need to add a couple of specific properties to the doc in-line.
