DCAT version 2: review request

Dear colleagues,

As mentioned during the SDWIG f2f meeting in Leuven [1], the Dataset Exchange Working Group (DXWG) has released on 28 May 2019 the final draft of the revised version of the Data Catalog vocabulary (DCAT):


This new version includes a number of extensions, some of which are relevant to spatial (meta)data. 

In particular:
1. The scope of DCAT has been extended to include data services / APIs as "first-class citizens"
2. New properties and classes have been added to cover spatio-temporal aspects - more precisely:
2.a spatial/temporal resolution, spatial/temporal coverage 
2.b specification of spatial coverage via geometries - including bounding boxes, and centroids
2.c specification of start/end of a temporal interval

On behalf of DXWG, I would like to thank you for the comments you already provided on point (1) [2] and (2.a) [3], and I kindly ask your review on the solutions adopted to address points (2.b) and (2.c).

The relevant classes and properties are the following:

- For 2.b, class dct:Location, and properties locn:geometry, dcat:bbox, dcat:centroid, w3cgeo:lat, w3cgeo:long, w3cgeo:alt - see:

- For 2.c, class dct:PeriodOfTime, and properties dcat:startDate, dcat:endDate, time:hasBeginning, time:hasEnd - see:


Thanks in advance for your feedback!

Andrea, on behalf of DXWG
