Dave,

I made two small fixes to the document.

First, there were some broken anchors and a leftover link to a non-existing qb:AggregatableHierarchy in the vocabulary index section. I also ordered the hierarchical code list terms alphabetically into the overall lists.

Second, there was an issue in the IC-19 section. The domain of skos:inScheme is unspecified in SKOS, and the range of skos:member includes not just concepts but also collections (for nested collections).

Because of this, the IC-19 constraint would accept observations where the dimension value is actually not a skos:Concept but a skos:Collection or some non-concept thing is in a skos:inScheme relation with the code list.

I fixed this by requiring { ?v a skos:Concept } as part of the FILTER NOT EXISTS clause for each part of the constraint.

I also tweaked the paragraph before the rule a bit for clarity.

Best,
Richard

This means that Chrome will not display the styling when viewed from https://dvcs.w3.org because it is a non-https link to a different domain. Firefox is happy and Chrome is happy with the live source so that's all we need.

I gave in trying to fix this at the respec end so did a manual replace of the copyright header of the respec output with the approved text. However, the copyright statement that pubrules suggests can't be cut and pasted directly because that breaks validation (sigh). So you have to take the pubrules text and replace "acronym" with "abbr" and than manually replace the respec output with it. I.e. with:

If you find this is too controversial at this stage, add a note along these lines: "At Risk: While this subsection provided useful context when this specification was first drafted, the editors feel that it is now only of historical interest and perhaps best removed in the interest of brevity." If removed, perhaps add a bit to the Acknowledgements: "Data Cube was motivated by a desire to improve on earlier work in the area of representing statistical data in RDF. The SCOVO specification, written by Danny Ayers, Lee Feigenbaum, Wolfgang Halb, Michael Hausenblas, Tom Heath and Yves Raimond, was a noteworthy inspiration."
