How to describe different information elements for searching for and binding to a service? In this case, it would be useful to provide the minimal information needed for connecting to a service.

Indeed, that's what I propose, i.e. DCAT is a vocabulary that aims to describe datasets, how to access those datasets is beyond the scope of this vocabulary, thus vocabularies dedicated for this scope should be considered.

 

The possible protocols or the vocabularies to be used may not be exactly the ones that were used in the case of RML. I mean these are all indicative cases applicable for RML, but it is not meant to provide a complete list of such vocabularies. If such an approach is followed, the working group may decide upon suggested vocabularies.

Dear colleagues

 

After the today virtual meeting, I tried to follow the Andrea Perego suggestion published here

https://www.w3.org/2016/11/sdsvoc/SDSVoc16_paper_27#modelling-service-a…   a:Dataset a dcat:Dataset;    dcat:distribution [ a dcat:Distribution ;     dct:title "GMIS - WMS (9km)"@en ;     dct:description "Web Map Service (WMS) - GetCapabilities"@en ;     dct:license <http://publications.europa.eu/resource/authority/licence/COM_REUSE&gt; ;     dcat:accessURL <http://gmis.jrc.ec.europa.eu/webservices/9km/wms/meris/?dataset=kd490&gt; ; # The distribution points to a service     dct:type <http://publications.europa.eu/resource/authority/distribution-type/WEB_…; ; # The service conforms to the WMS specification     dct:conformsTo <http://www.opengis.net/def/serviceType/o   In practical implementation this means to set in CKAN (my platform) some attributes that we extended in order to implement DCAT-AP (IT)   A practical example on our catalogue (through the CKAN API and through the DCAT-AP JSONLD API ) The values are inserted manually.  "URL" is the "AccessURL"   type: "WEB_SERVICE" url: "http://www.comune.pomarolo.tn.it/api/opendata/v2/content/search/classes 'event'", license_id: "cc-by" conforms_to: "compliant to REST/JSON",   You could see the result here   http://dati.trentino.it/api/3/action/package_show?id=eventi-del-comune-… http://dati.trentino.it/dataset/eventi-del-comune-di-pomarolo.jsonld   Is that dataset compliant in that way as "service-based access"? Anything about the "size" attribute?
