jimjyang has just created a new issue for https://github.com/w3c/dxwg: == Suggestion to add dct:format and dcat:mediaType to dcat:DataService == ### formats and mediaTypes of a DataService Status: idea Creator: Jim J. Yang Deliverable(s): DCAT3 ## Stakeholders Providers of DataServices/APIs Consumers of DataServices/APIs Providers of Service Catalogs Consumers of Service Catalogs ## Problem statement Which formats/mediaTypes a DataService may support is one of the considerations you need to take when deciding whether a DataService is (re)usable or not. In the 2nd Working Draft of DCAT3, dcat:DataService (still) doesn’t have properties dct:format and dcat:mediaType as in dcat:Distribution. Possible ways to describe formats/mediaTypes of a DataService are thus: 1. Using dcat:DataService/dcat:endpointDescription. The main disadvantage is that it doesn’t necessarily ensure a standardized way of expressing formats and mediaTypes, which makes it impossible to e.g. sort/query DataServices according to formats/mediaTypes. 2. Using dcat:DataService/dcat:servesDataset -> dcat:Dataset/dcat:distribution -> dcat:Distribution/dct:format (or dcat:Distribution/dcat:mediaType). The main disadvantage is the unnecessary overhead in creating and maintaining all those extra Distributions (and Datasets). ## Requirements Add the following properties to dcat:DataService: - format, dct:format, dct:MediaTypeOrExtent - media type, dcat:mediaType, dct:MediaType ## Related use cases ["How to express available formats for a dcat:Dataservice (Issue #1055)"](https://github.com/w3c/dxwg/issues/1055), which was “tagged as a future priority”.
