Re: DCAT comments - dataset dependecy - http://www.w3.org/TR/2013/WD-vocab-dcat-20130801/

Hi Sandro, Fadi,

 

1) Thanks for following up.

 

The reply classifies our request as being out of scope of DCAT - so any application seeing the use of declaring a conforming standard as relevant will require a custom extension.  This could be done by:

- an extra custom property,

- a void property in case the set is available as RDF,

- using a dedicated theme,

- …

Many ways to get around.

 

 

2) In case there is still room for amending some text, I would suggest:

a) Replace all references to the deprecated vcard:VCard by the replacing vcard:Kind or any of its sub-classes.

b) To make the usage note on dcat:mediaType more explicit.

     Add to usage note: “Best practice for retrieving a data using dcat:downloadURL is to set the HTTP header ‘Accept’ to a value of dcat:mediaType.”

c) Add note that dcat:accessURL and dcat:landingPage are of type html or xhtml

d) It is not clear how a multilingual dataset can be registered that has different distributions per language

     either -d.1- using a different dcat:downloadURL

          With the current model, this situation can be handled unambiguously by having multiple (further unrelated) data sets.

          If this is considered best practice, this could be clarified in a usage note on dataset dcat:language

     or -d.2- using the same downloadURL but with different values for the HTTP header Accept-Language

          With the current model this could be handled by adding a usage note on the dataset dct:language and on the distribution dcat:downloadURL

Sorry for these late results on an implementation exercise we made with the EU Publication Office CELLAR platform.

 

Kind Regards,
