All fine if your intention is just to produce rdf (a noble thing in itself)
There seem to be 2 sets of criticism of this work:
1. It's not a definitive mapping to rdf-a - just a very reduced set of rdf-a
markup. But unless GRDDL does more than just glean then it too is only going
to produce a reduced set rdf representation. It's not going to take a
contact:fn and know it's a mo:MusicGroup or a mo:MusicArtist. So the same
limitations apply to Manu's work as apply to GRDDL - you can only glean
2. It duplicates work between ufs and rdf-a. Probably true but... As above I
don't think it's anyone's intention to map ufs to fully expressive rdf-a.
The work required by both publishers and consumers would be too much. Rather
it seems like an attempt to map the simple models of ufs onto the goodness
of rdf-a. So just rdf-a flavoured microformats (or nana-formats given the
flexibility of rdf - sorry). What it does buy us is namespaces and that,
imho, is a GOOD THING and missing from ufs
I am in no way criticising microformats and the work done here - it's all
really cool and works for 80% of users in 80% of cases. Adding namespaces
might just make it work for another 10%.
Apologies if I'm putting words/opinions in the mouth of Manu - not my
