RE: Done (Was Re: DCAT turtle)

Dear Phil and others,

Many thanks for doing this effort and have the turtle file updated. Basically, my Phd research is about the semantic enrichment of 'spatial policy indicators'. I will analyze existing vocabularies such as DCAT and Data Cube vocabulary and check to what extent they can be applied for this type of data.  In particular attention will be paid to provenance (from which sources is the indicator derived and how?), the geospatial component (Are there elements from ISO19XXX and INSPIRE we could reuse), the granularity and the link to the corresponding policy domains (SKOS for defining taxonomies). So probably I might end up in a proposal for a DCAT profile including additional elements for provenance, spatial properties, etc... Why? Government and decision makers currently experience a lot of difficulties bringing together the necessary indicators to prepare and monitor policy objectives and measures. For example, in Flanders the ministry of Spatial Planning only has limited access to data and indicators produced by other departments, and certainly not in a format that allows further processing and combining. Actually, the information silos continue to exist and there is no cross-domain platform to exchange useful figures.

This is in a nutshell the theme of my Phd research. Not so theoretical, but more oriented to try stuff in practice.

Any feedback and suggestions are more than welcome!

Kind regards,

Diederik Tirry

Subject: Done (Was Re: DCAT turtle)

Hi all,

I am very grateful to Fadi, Boris, Marios and Ghislain for their translations of the DCAT turtle file which is now in place at http://www.w3.org/ns/dcat.ttl. Please check, including the metadata. If I can improve this, please shout.

John asked the perfectly reasonable question: how can we keep these languages in sync? I guess the short answer is that we can do it as long as there is willingness to do so. The terms are defined in a doc in /TR space - so that doc will never* disappear. The terms in the Turtle file match those and we'll never* delete them. We may deprecate them, yes; we may clarify, but not change, the semantics; and we may add new terms (the proposed Data on the Web BP WG is specifically chartered to do so for example). If new terms are added and we can't draw on our friendly neighbourhood speakers of Arabic, French, Greek and Spanish - well, they won't be localised. But I suggest we cross that bridge when we come to it.

What's good now is that we have a schema that matches the spec and an example of a very multilingual approach, the value of which we should be able to assess in the coming months.

Cheers

Phil

*Never is a very long time. I mean W3C has a public commitment on this and that for as long as it exists, and for as long as its 4 hosts exist, the files in /ns will be preserved. Now, when the Web disappears, as it surely will do some time between now and the heat death of the Universe, well... we tried folks.
