Dear all,

On a telecon of the DCMI Schema.org Alignment Task Group tomorrow, we will 
discuss how best to publish mappings between Schema.org and DCMI terms.

Initially, I pulled together a wiki page to show proposed mappings together
with the definitions of the relevant terms [2, above].  This was a tedious
process of cutting-and-pasting, and as Dan pointed out, it really highlights a
need to improve the documentation of both vocabularies -- an observation that
led to the current push to complete the task of modifying the scripts to
generate DCMI Metadata Terms with RDFa.

In chats over the past few days, I have heard it suggested that RDF data could
be maintained in Turtle and used to generate RDFa.  I wonder whether that could
be a longer-term goal for the DCMI Metadata Terms work -- i.e., to maintain the
source data in Turtle instead of in the ad-hoc XML markup we currently use [5];
however, that would surely require a re-write of the scripts beyond what we
could realistically undertake in the near term.

I wonder, though, whether such a workflow might be adopted for producing a
simple Web page for DC/Schema.org mappings.  Antoine Isaac has started
converting my tediously assembled wiki page [2] into RDFa [6,7], and this could
be the basis for a more "presentable" way to publish the mappings, with
document anchors [8] that would be citable in issue trackers.  As I understand
it, however, the RDFa document would require no less hand editing than the wiki

Ideally, readable documentation for the vocabularies being mapped would be just
a mouse-click away and it would be unnecessary to cut-and-paste definitions.
In that case, the mappings could perhaps be maintained in Turtle or N-Triples
and published in XHTML/RDFa -- as DCMI Metadata Terms will soon be, only with
perhaps a simpler format, using simpler scripts.  Ideally, of course, we would
be able to publish the mappings together with provenance information for each
mapping -- who, when, and status -- and with HTML anchors that could be used
for citing a particular mapping, for example in an issue tracker.

If any of you see how we might do this efficiently, please post your ideas.
You would also be most welcome to participate in discussion on the
dc-architecture mailing list [9] or join in the discussion on tomorrow's
telecon (see joining information below).
