Distribution schema [RDIS]

Distribution schema [RDIS]

Define a way to include identification of the schema the described data conforms to

This may include rich information via extensions points, URI templates and parameters, dimensions and subsetting operations, dereferenceable identifiers of service behaviour profiles and canonical identifiers of well-known web service interfaces (e.g. OGC - WFS, WMS, OpenDAP, REST apis).

Such a description may be provided through identifier of a suitable profile that defines interoperability conditions the distribution conforms to.

The European DCAT-AP (https://joinup.ec.europa.eu/release/dcat-ap-v11) specifies the use of dct:conformsTo (http://dublincore.org/documents/dcmi-terms/#terms-conformsTo) with usage note "This property refers to an established schema to which the described Distribution conforms." This seems like a solution to the issue as defined in the first line.
The remainder of the text in the issue description could be part of a usage note.

Notwithstanding little evidence of usage in SEMICeu/DCAT-AP#25 I agree that this looks an eminently practical solution which could be promoted into DCAT.

Proposal: add dct:conformsTo to the list of properties recommended for use with dcat:Distribution https://w3c.github.io/dxwg/dcat/#class-distribution

+1 from me.

BTW, another supporting use case is 5.18 Modeling service-based data access (which however is not linked from this requirement).

Schematic representation is approximately parallel with FRBR 'Expression' - see https://en.wikipedia.org/wiki/Functional_Requirements_for_Bibliographic_Records

In contrast, syntactic representation, media-type or format can be compared with FRBR 'Manifestation'.

Proposed resolution in #297

[jakubklimek]

+1. In SEMICeu/DCAT-AP#25 I added my arguments why the discussion there is invalid. This property is crucial.

[dr-shorthair]

Additional changes to #297 after discussion https://www.w3.org/2018/07/12-dxwgdcat-minutes#x07
should resolve the issue per the resolution in that meeting.
