The W3C RDFa Working Group has just published the “Last Call Working Draft” for RDFa Core 1.1. As Manu Sporny, the co-chair of the group, said in his tweet, this W3C jargon is equivalent to a “feature freeze”. Ie, the group does not know of any outstanding technical issues and of missing features that it would reasonably plan to add. Put it another way, this is last round of commenting before proceeding to final implementation testing and, hopefully, to a final W3C Standard. I.e., Last Call doesn’t mean that the group takes no more comments; on the contrary, technical comments are very welcome and necessary to make it sure that the final outcome is correct. Please, send your comments to the groups mailing list: firstname.lastname@example.org (there is also a public archive).
Although lots of things have been discussed in the past few months (i.e., since the last draft published in August) not many things have significantly changed, in fact. Most of the changes are editorial, making the text clearer, more precise, etc. (You can look at the “diff” file, if you are interested.) This document is for the Core, i.e., the generic RDFa processing that can be used for any DOM. It is to be expected to have, in a few days, a similar document published for XHTML+RDFa 1.1 by the same Working Group, and an HTML5+RDFa 1.1 by the HTML Working Group.
I have also worked, in parallel to the specification work, on a modified version of the RDFa distiller. While the “official” service remains unchanged and relies on the current RDFa Recommendation, there is now a “Shadow” version, that relies on RDFa 1.1. The underlying code has undergone some cleanups beyond the adaptation to RDFa 1.1 so I am sure there are bugs…
Finally, a blatant self-promotion: Stéphane Corlosquet, Lin Clark and I will give a tutorial at the upcoming ISWC conference in Shanghai on RDFa and Drupal. The RDFa part relies on 1.1… (There are links to the slides on the page but you do not expect us not to touch them any more before the tutorial itself, do you? So make sure you look at them again after the event…)
