RE: [ACTION 11] Initial DCAT to meta-share mapping

Hi John and all!

 

Maybe the confusion comes from me, sorry for that: I thought the two documents were complimentary, with the wiki providing the principles for the mapping and the spreadsheet including the detailed mapping. So, I decided to put in the wiki the rationale and (since I though the mapping was under discussion) check the detailed spreadsheet once the general decision was made; I had already added some comments inside the spreadsheet. Anyway, do I have time to send in some comments for the final mapping by tomorrow?

BTW, I 'm not sure what the mapping of the various ms.BabelNet, ms.ComputationalLexicon etc. to dcat.Dataset is: are they going to be subclasses of dcat:dataset or replaced by it or ???? There's an ongoing discussion as regards the mapping of ms:LanguageResource to dcat:Dataset as there's an overlap between them.

 

And I was having a better look at the licensing module to make sure all the MS elements are there and correctly mapped to odrl and other vocabularies; is this ok?

 

Best,

Penny

 

BTW, I had a quick look at the github and I think there are some "copy-and-paste" errors – e.g. in the mapping of MS.metadataCreationDate I see FOAF.primaryTopic as well as the dct.issued.

Hi,

There seems to be some duplication here as the metashare to DCAT mapping to the spreadsheet here:


https://docs.google.com/spreadsheets/d/15SE4_qAqYFostmD52uKxpkCPZh1f5TrPeoXKNTlDYpQ/edit#gid=0

Can one of the LD4LT/LIDER chairs please decide which document we are using??

 

The mapping in the spreadsheet is already implemented here:


https://github.com/liderproject/metadata-harvesting/blob/master/metashare/fix_metashare.py

 

Regards,
John

Hi Dave and all.
I've made some comments (in italics to easily spot) at the wiki for the
MetaShare to DCAT mapping. Please, note the following:
- the proposal looks only at dcat:dataset and dcat:distribution but there
are also dcat:catalog and dcat:catalogRecord. MetaShare has not looked at
catalogs at all, but some of the elements can be mapped to
dcat:catalogRecord properties. Should we look into this also?
- Some of the comments refer to the XML implementation of MetaShare (i.e.
elements that have not been included in the current version of MS/RDF-OWL)
but I have added them as they will be of use for the final XML to RDF
conversion of the original MetaShare schema.
Best,
Penny

Subject: [ACTION 11] Initial DCAT to meta-share mapping

Hi all,
I've made an initial analysis of how we can make use DCAT in revising the
meta-share vocabulary at:
https://www.w3.org/community/ld4lt/wiki/DCAT_MetaShare_Mapping

Some points we can discuss on the call shortly:

1) classifying ms:LanguageResource as a dcat:Dataset - see:
https://www.w3.org/community/ld4lt/wiki/DCAT_MetaShare_Mapping#Make_Language
Resource_a_DCAT_Dataset

2) separating meta-data about the resource from meta-data about its
accessible forms or distributions - see:
https://www.w3.org/community/ld4lt/wiki/DCAT_MetaShare_Mapping#Separate_Lang
uageResource_metadata_from_metadata_of_its_Accessible_Form

3) (which I haven't documented yet) is using dcat:theme attribute for
LanguageResource properties that comply to a specific scheme or taxonomy
using skos:concept and skos:ConceptScheme. This would make sense for
ms:domain, but also perhaps for making explicit the subclass taxonomy
LanguageResource, e.g. Corpus etc.

Talk to you shortly,
Dave
