Dear Frans, dear Alejandro, I’m including below some general comments to the UCR document. Cheers, Andrea ---- 1. I don't see a requirement about the fact that spatial data must be available in multiple formats. This is something that popped-up quite frequently during the discussions in Barcelona, and it is implied by a number of requirements. I think this is something that must be explicitly and clearly stated, and it goes together with the linkability requirement, as both are key principles for the Web architecture. 2. Many of the requirements may apply both to data and metadata. It would be useful to clarify the use of "data" in the UCR document: whether it applies only to data, or to metadata as well. 3. Req 5.42 - Spatial metadata: This requirement is missing the "temporal" dimension, that is implied in a number of related UCs. See also my mail https://lists.w3.org/Archives/Public/public-sdw-wg/2015Apr/0123.html I suggest we revise the bullet list as follows: - coordinate reference system(s) -> spatial and temporal reference system(s) - spatial extent -> spatial and temporal extent - spatial resolution -> spatial and temporal resolution BTW, in my understanding, this requirement is already implying quite a few of those we have at the moment in the UCR doc - as bbox and centroid, crawlability, discoverability, multilingual support, spatial and temporal vagueness, time series, valid time, nominal temporal references, etc. I’m just thinking aloud, but I wonder whether we should keep a separate requirement for metadata. At least, in the current version of the UCR doc, the scope of this should be clarified. 4. Req 5.6 - Crawlability: This requirement should concern both to data and metadata. See also points (2) and (3) above. -- Andrea Perego, Ph.D. Scientific / Technical Project Officer European Commission DG JRC Institute for Environment & Sustainability Unit H06 - Digital Earth & Reference Data Via E.
