Re: PDF's usefulness to the semantic web

Dave, Bobby,

I think we are talking about ISSUE-18 again here, what standards  
besides W3C's should be added to the document. Some comments about this.

I'm sure we all agree on the usefulness and heavy use in government of  
several standards beyond W3C's. Said that, here's my rational _not_ to  
include those you are referring to (and others).

1) This is W3C and the document is titled? "... of the Web" and I  
prefer to stick to Web standards for now. For me, e.g. PDF/A and OOXML  
are not Web standards but something you can link to from the Web, as  
you can link to a ZIP file. Not an expert in the field and welcome any  
additional info but quite sure we could discuss for hours and hours  
what is Web and what is not and we would probably have as many  
versions as group participants.

2) I would like to see the Web-related use cases to add this or any  
other technology and not adding them just for growing the list of  
standards referenced in the document.

3) Why add only ISO ones, why not IETF ones or others'?
As an example, I recently learned about the study for the catalogue of  
standards usable by governments here in Spain, and heard Miguel Amutio  
speak about it saying 400 coming from dozens of bodies were analyzed.  
Not to mention other similar initiatives such as the U.S. TRM.

4) We don't have a liaison with ISO and I would prefer this Group not  
to make interpretations on the use of standards developed by other  
organizations without discussing with them how they fit in our work.

Scoping the Group's work was a difficult challenge and I don't think  
that broadening the scope now that the charter is about expire makes  

I think we should disregard this for now but discuss it when  
developing the 2nd charter, see if we should work on a broader suite  
of standards, setup a liaison with more SDOs, etc.

One more comment, you mention:

I wish we had some text in the "Long Term" section but we don't yet.  
There were former IG Members tasked to provide use cases on the  
differences you mention. I remember we were going to get a use case on  
"Temporal Data" but unfortunately that didn't happen.

Sticking to the Web standards part above, I think that section was  
intended to talk about "Web Archiving" and maybe the closest view is  
that of the draft use case John submitted a while ago --
