Dear DM Editors, I've read 'A Direct Mapping of Relational Data to RDF' [1] in the revision $Id: EGP.xml,v 1.5 2011/08/05 18:07:37 eric Exp $ and have the following comments and suggestions. Great job, so far and sorry for the late notice, I hope you still find time to address some bits till our call in 5h time ;) + In the beginning of the document (Abstract/SotD/Introduction) I would expect to find a sentence regarding the target audience. We have discussed this over and over again and I honestly do not care so much how you phrase it, but I insist on making this explicit, *pretty* please. + It is hard to tell which sections are normative and which are informative as the policy is not explicitly stated (the ToC gives a hint, but it would be better to explicitly say something along the line: [[all sections not marked with 'Informative' are in fact normative sections]] + The 'Appendices' starts without a heads-up or explanation why this is here. A sentence to clarify what the purpose of A. and B. is and/or for whom this is relevant would increase the readability. + You have a number of issues listed inline. They should be linked to 'real' issues in the tracker (currently I count three DM-related issues there, ISSUE-63, ISSUE-42 ISSUE-40, the rest have been postponed) and the deprecated ones should be removed - check against [2]. + I often stumble upon sentences with a lot of brackets, such as from Sec. 3: [[An (addressable) SQL table has a set ...]]. Either the stuff in the bracket is important, then remove the bracket, or the stuff in the bracket is not important, then remove it at all. + Sec. A2 uses 'set' and 'multiset' without defining it. Now, one could argue everyone knows what a 'set' is (but why not just stating it, like: [[A set is an unordered collection of distinct items.]], however with the 'multiset' definition I dunno, this is not obvious I think. Unfortunately my mathematical inability prevents me from coming up with a clean definition, heck even our SPARQL WG colleagues resort to Wikipedia for this [3] - thanks Nuno for pointing this out - so all I can ask here is: please address this. Other than that: great stuff, I like it very much and I hope after today's call the WG as a whole will acknowledge that this document is LC-ready, modulo minor polishing stuff.
