New capabilities in DCAT revision

[dr-shorthair]

I mentioned here https://github.com/ckan/ckanext-dcat/issues/105#issuecomment-376399708 that DCAT is in revision. Most proposed changes are extensions and do not break implementations based on DCAT-2014. The following might be useful:

• dct:creator recommended for use on dcat:Dataset to support better citations
• prov:wasGeneratedBy on dcat:Dataset to link to a description of the activity or project which generated the dataset
• dct:relation on dcat:Dataset to link to related resources, including other datasets, parts, documentation, metadata_created
• DQV recommended for data quality information
• new class dcat:DataService to support cataloguing of services, with specializations dcat:DataDistributionService and dcat:DiscoveryService

More coming.

A second public release of the revision of DCAT has been made - see https://www.w3.org/TR/vocab-dcat-2/
In particular note

1. support for cataloguing services https://www.w3.org/TR/vocab-dcat-2/#vocabulary-overview and https://www.w3.org/TR/vocab-dcat-2/#data-service-examples
2. recommendations for datasets published as a 'bag of files' - motivated in part by CKAN - see https://www.w3.org/TR/vocab-dcat-2/#bag-of-files

Feedback is requested. https://github.com/w3c/dxwg/issues

I'll test the updates I'm about to make to the plugin for Conneg by Profile with the two flavours of DCAT.

It might be worth adding a link to https://www.w3.org/2013/dwbp/wiki/List_of_DQV_implementations

dct:relation is implemented via extras:related_resource since https://github.com/ckan/ckanext-dcat/commit/f060032e3f7b0d885627583f540a9e01f527bcf8 but it is missing in the README mapping table, I guess that was an oversight.
