Re: Exposing datasets with DCAT (partitioning, subsets..)

Hi Maik,

I’ve only had chance to skim this but I had a question about the first (well, second) line on the Wiki page! Is dct:hasPart strictly for *non-overlapping* subsets? I can think of use cases where subsets might overlap. For example, let’s say that there is a global surface temperature product that is available as a set of sub-datasets, one for each continent (for user convenience). The continent boundaries would probably be simple lat-lon bounding boxes and would probably overlap at their edges. Would this be allowed?

Cheers,
Jon
