Data Catalog Vocabulary (DCAT) v3: 2nd Public Working Draft

This message is to update you on the work of the W3C Data Exchange Working Group [1] and to ask for your help in reviewing progress on the third revision of the RDF vocabulary for data catalogs, DCAT, that was published on 04 May 2021. The Second Public Working Draft of the revision is available at https://www.w3.org/TR/2021/WD-vocab-dcat-3-20210504/

The revision of DCAT is part of a group of deliverables described in the Charter [2], but it can be read as a stand-alone recommendation on how catalogs of resources should be published on the web..

This version especially focuses on the areas of versioning [3]  and dataset series [4]. The list of changes since the first public working draft of 17 December 2020 is available at [5]. 

In reviewing the draft, it might be helpful for you to keep in mind the initial “Use Cases and Requirements” document that we are working towards [6], the issues log associated with this milestone in the development of the recommendation [7] and the remaining issues [8].

We welcome feedback along the following lines:

1. Do you agree with the direction of travel of this revision of DCAT?
2. Are there any areas where we could improve what we have done? [please illustrate]
3. Are there any areas where you think the proposal is wrong or could lead us into developing proposals that are erroneous? [please give examples and reasons]
4. Are there other use cases for data catalos and datasets descriptions that we have not considered? [please illustrate]

Please also feel free to make any other comments and suggestions regarding the draft.

Please, send comments through github issues (https://github.com/w3c/dxwg/issues) or through email at: public-dxwg-comments@w3.org
