[ckan-dev] CKAN DCAT-AP 1.1 Integration

Wed Jan 27 15:19:28 UTC 2016

Great! It could really useful to have this extension in place, instead to do our custom implementation (we are Dati.Trentino.it)Do you have an idea when it could be available? I imagine you have a lot of other stuffs to do, just an idea..
I was hoping that this piece of cake could come directly from the EuropeanDataPortal project, that are leading the implementation of this standard in reality (and using CKAN!). For who don't know, tomorrow there will be a webinar about implementation guidelines of DCAT AP 1.1 (more info here https://joinup.ec.europa.eu/node/148697)
I didn't see any reply to your email, but for sure, for us it is a super-very interesting for anybody that is building a opendata portal on CKAN. There will be for sure some adaptations from country to country (for example in italy we have some additional fields, some are mandatory instead than recommended) but a basic core will be very similar.
I just comparing the RDF available under "/examples", and I noticed that just one is changed recently (dataset.rdf), not sure if it is reflecting the changes you mentioned before.
Looking at it, I see that there are differences in the vocabularies .  Eurovoc is gone and many fields need to refers to MDR EU (http://publications.europa.eu/mdr/authority/)
I list these: data-themes: http://publications.europa.eu/mdr/authority/data-theme/index.html
languages: http://publications.europa.eu/mdr/authority/language/index.htmlfile types: http://publications.europa.eu/mdr/authority/file-type/index.htmlfrequency: http://publications.europa.eu/mdr/authority/frequency/index.html
Then, in some cases, it could be better to add some metadata to the organizations (CKAN allow to do that, adding extra fields to the organizations), like contact point, and Unique ID (if there is one) and having them inside  foaf:Organization 
I was also looking at some other interesting metadata that seems not present also in DCAT 1.1, for example the "charset" of a distribution (resource in CKAN). I think it should be mapped with the distribution (as for the license), but in the worst case needs to me mapped (1 to many) from CKAN Dataset -> DCAT-AP1.1 Distribution
Thanks  a lot for your effort, surely we are gonna test it and use it when available.
