- 08:59:24 [PWinstanley]
- https://github.com/difi/dcat-ap-no/issues
- 09:00:13 [arminhaller]
- roba: Versioning in general would be a different type of relationship. dcat:revision to be a backward compatible, i.e. original DCAT would become a profile of the new DCAT
- 09:00:34 [arminhaller]
- s/to be a/to be
- 09:01:10 [arminhaller]
- AndreaPerego: I am not sure if these two relations can be modelled with the same relationship type.

- topic: Discussion of priorities and actions
- 09:04:26 [roba]
- * Nick - we should split the version example into a separate file, with a more exploratory status...
- 09:05:09 [arminhaller]
- SimonCox: Most of the discussion on the mailing list recently has been on the profile discussion, rather than on DCAT itself

- ... they are taken from the use cases
- 09:12:46 [arminhaller]

- 09:13:23 [SimonCox]

- 09:14:28 [arminhaller]
- SimonCox: Are these qualified relations changing the DCAT vocabulary, or are they just best practices how to use the vocabulary in combination with other vocabularies
- 09:14:59 [arminhaller]
- AndreaPerego: Yes, we don't need to add anything. We just recommend how properties can be used in qualified relations using the PROV ontology
- 09:15:43 [SimonCox]
- ... look at PROV mappings to DC as exemplars?
- 09:15:52 [arminhaller]

- 09:21:23 [riccardoAlbertoni]
- +1 to have more guidance in dcat document
- 09:21:36 [arminhaller]
- SimonCox: My assumption is that the DCAT document needs to include more documentation, guidance and examples.
- 09:21:48 [arminhaller]
- ... expectation is that we have more example in the document.
- 09:22:05 [AndreaPerego]
- Indeed, the lack of examples in DCAT 1.0 has always been an issue.
- 09:22:10 [arminhaller]
- ... preference is that the document becomes more guiding rather than just a spec
- 09:22:57 [arminhaller]
