Dear all,
The response to the Doodle poll for a TG telecon next week has been
limited [1], but I have had a chance to speak off-line with Jon and
Antoine about next steps.
Recall that the document on which we are focusing is mappings.html [2]
-- the RDFa/HTML document that Antoine started to create on the basis of
[3], itself based on [4] (viewed as ntriples [5]).
The new mappings.html with RDFa [2] is only partially done. What
remains to be done:
-- encode the rest of the triples (e.g., compare [5] with [6])
-- give each triple an anchor address (e.g., [7])
-- delete the cut-and-pasted term definitions. For one thing, they
use http://schema.rdfs.org/all.nt, in turn based on
http://schema.org/docs/schema.org.owl, but as discussed on the most
recent call, this is problematic.
-- give each term block a template where we can indicate the status of a
given mapping (so that we can finally start taking decisions on
mappings!) and places to put links to mailing-list discussion, links to
examples, and the like.
In the meantime, DCMI is preparing a major maintenance release of DCMI
Metadata Terms with embedded RDFa. The document can now be generated in
RDFa/HTML [8] and we are debugging the mechanics of content negotiation.
I believe Dan is looking at similar ways of resolving Schema.org URIs to
Web documents. Being able to click on the term URIs and see readable
documentation will make it unnecessary to cut-and-paste such information
into a mapping document as it will be just a mouse click away.
Jon is looking at ways the mappings.html document might be made easier
to maintain. He may be able to present some of these ideas next week,
but it will be too late for holding a telecon -- at any rate before I go
offline (as described in [9]), though my extended absence need not put
further progress on hold.
Currently, we are aiming at having a discussion about Jon's ideas next
week on this list. By August, one way or another, we would ideally have
a nice and easy-to-maintain mapping document in RDFa/HTML, with citable
URIs for individual mappings, and can finally just go down the list and
assign to each one of them some sort of approval status.
This progress is taking longer than I expected, but some good things are
getting done as by-products (such as DCMI terms in RDFa). We are
putting into place a solution that will hopefully scale to mappings to
other vocabularies as well.
