I tend to think that non-information/off-web things like equipment is out of scope for DCAT. 

However, 'dataset' (or even 'data') is just a sequence of 1s and 0s, so to me things like software, source code, vocabularies and ontologies, as well as images, other multi-media, models and other structured data are all in scope. 

Of course this is exactly the issue that UC ID8 was attempting to raise. You suggest that ' those things could be either subclasses of dcat:Dataset or be identified with a type property'. Of course the very special rdf:type property joins those two ideas together. In general I expect that the list of types (semantic types, not media-types of course) needs to be extensible and thus maintained separately from the core vocabulary, probably in more than one place. See Andrea's spreadsheet for some candidate lists - https://docs.google.com/spreadsheets/d/1nlAgLUGQcBe40oTk5WNCVz-6rud1JtLwjoYyyqAT45U

Phil,

The D in DCAT may not be the problem. After all, D stands for Data -- DCAT is the *Data* Catalog Vocabulary, not the *Dataset* Catalog Vocabulary.

Maybe we could look at different approaches for different types of resources, e.g.

a. if something is not *data*, maybe there is a need for a different vocabulary alongside DCAT, e.g. an Equipment Catalog Vocabulary, Service Catalog Vocabulary etc. This might be out of scope for this WG?

   or

b. if something is not a *dataset*, maybe there is a need for a class of things alongside the dcat:Dataset, so a dcat:Catalog could contain dcat:Dataset and dcat:Equipment and dcat:Service etc.

   or

c. if we want to lump all kinds of 'things' together under dcat:Dataset, those things could be either subclasses of dcat:Dataset or be identified with a type property.


Makx.

On a more general point, a couple of times people have suggested to me that the D of DCAT is sometimes unhelpful; that is, one might think in terms of a catalogue vocabulary, where the items in the catalogue
*might* be datasets, yes, or, perhaps things like equipment (think projectors and smart boards in university campus).

The current definition of a dataset is (deliberately) so broad that it's close to the definition of the more general notion of an 'Information Resource'
