As Gretchen points out, there are some questions raised by Appendix C.2. TAP services to be marked up in such a way should I think use the TAPRegExt <dataModel> element, but I'm not sure about Cone Search.

The response curve in the example table in Appendix C.1 seems to have all its transmission values as zero - is that a mistake?

Given consideration of those points, I approve.

-- MarkTaylor - 05 Jul 2012

Agree with first point. Tap services could make use of the datamodel element. As commented in the registry section, details on how to register cone search services can be considered out of the scope of the DM itself, so they should be discussed in another context.

About second point, unfortunately the example has been taken from a real example and cut to minimize the size (the first element are zero). The example will be modified to get transmission numbers different than zero.

Appendix C.2 describes using a new capability type for Cone Search, i.e. Photometry. This is confusing to me, in the sense that the capability is more what we would refer to as the standard functional capability, e.g. cone, sia, ssa, sla, tap, etc. It is an interesting concept you are defining, i.e. how to describe data model implementation contained in a specifc service capability. I'm looking further to try to understand this in the context of registry schema. Currently i do not see the metadata mapping which would demonstrate how this would comply. Perhaps you had a specific example to explain further?

GretchenGreene - July 3, 2012

This was a proposal done, mainly, by our CDS colleagues in order to publish future Cone Searches with the extra metadata information. I agree this should be more discussed in the registry context and, as mentioned, the services should be registered using a standard registry extension (e.g. TAPRegExt for tap services). As this is out of the scope of the DM itself, I will remove some details on how to register these services. This could be added to the related IVOA note in coordination with the Registry group

The document is clear and comprehensive.

I approve the document.
