WG decision
The RDB2RDF Working Group made the decision for the LC transition at its teleconference on 13 Sep 2011. This Last Call period ends on 1 November 2011.
Procedure for handling Last Call comments
As discussed and agreed during the teleconference on 20 Sep 2011, the WG will apply the following procedure for handling Last Call comments (until 1 Nov):
- For each LC comment via the public-rdb2rdf-comments mailing list, one of the Editors (R2RML, DM) reacts within (ideally) three days
- The chairs can act as a fallback if the Editors declare that they are not able to react
- For each non-editorial comment, the Editor who answers answers creates an issue in the WG Tracker
- For each editorial comment, the Editor who answers prepares an update of the respective ED and informs the person who commented via the public-rdb2rdf-comments
- The same procedure as outlined above applies for WG members sending in LC comments

4 R2RML: Subject: RDB2RDF Last Call Working Draft transition announcement
- Reporter: Bob Ferris
- http://lists.w3.org/Archives/Public/public-rdb2rdf-comments/2011Sep/0005.html
Response
- ISSUE-62 (generate IRIs or other RDF term by calling an external function) had been postponed as a post-R2RML-1.0 feature.
- ISSUE-72 (bring back lookup tables) has been raised and would at least partially address the comment.
- The issue was closed without re-adding lookup tables, but with the addition of an R2RML views example that implements a simple translation table: http://www.w3.org/2001/sw/rdb2rdf/r2rml/#example-translationtable
- Formal response: http://lists.w3.org/Archives/Public/public-rdb2rdf-comments/2011Dec/0000.html

Miscellaneous feedback
This is feedback that the WG became aware of, but that wasn't raised formally as a last call comment and thus didn't require a response from the WG. Editors have taken some of the feedback on board.

Changes to DM between LC and CR
High-level Changes since the Last Call Working Draft:
- The definition of literal map was subsumed by the definitions for natural RDF literal and canonical RDF literal in the R2RML specification.
- Quoted identifiers (table and attribute names) in SQL examples in order to clarify the case of the created schema.
- Minor corrections in examples of direct graphs.
- Updated Denotational Semantics and Rules to reflect above changes.
