Data Specification Vocabulary (DSV) and its Default Application Profile (DSV-DAP)
In this repository, two Semantic Data Specifications are hosted:
- Data Specification Vocabulary (DSV) - supporting vocabulary
- Data Specification Vocabulary Default Application Profile (DSV-DAP) - application profile of DSV, PROF, and other vocabularies for description of Semantic Data Specifications.
Examples
Embedded specification metadata
This is an example of JSON-LD metadata embedded in a data specification such as the ones above.
In the example, we can see that the specification document, published at a persistent URL https://w3id.org/dsv/, is an instance of dsv:VocabularySpecificationDocument, adms:AssetDistribution and prof:ResourceDescriptor.
It has a Guidance role, HTML format, and is one of the artifacts of the specification (inSpecificationOf) DSV, identified by https://w3id.org/dsv#, which is a prof:Profile and owl:Ontology.
Then we can see other artifacts of the specification in hasResource, and links to reused specifications and, specifically, where they can be downloaded (isProfileOf).
Using this metadata, complian editors, such as Dataspecer can find and use the artifacts contained in the data specification.

Representation of term reuse in Application Profiles
For application profiles, one of the contained artifacts is the DSV file created according to the DSV-DAP. It contains information about the terms reused in the AP.
The AP itself can contain metadata compliant with FOOPS!:

Below is an example of a class profile from our version of DCAT-AP 3.0.1, i.e., reuse of a class from DCAT Default Application Profile.
It shows the definition of the Class Profile for Dataset in DCAT-AP. It is a dsv:ClassProfile, with a custom definition and with a scope note, and we can see that it is a dsv:profileOf https://mff-uk.github.io/specifications/dcat-dap#Dataset.
In addition, we can see that the title (skos:prefLabel) is taken from the DCAT-DAP dataset as-is, without change (contrary to the definition through dsv:PropertyValueReuse.
:Dataset dct:isPartOf <https://mff-uk.github.io/specifications/dcat-ap#>;
a dsv:TermProfile, dsv:ClassProfile;
dsv:profileOf <https://mff-uk.github.io/specifications/dcat-dap#Dataset>;
skos:definition "A conceptual entity that represents the information published."@en ;
skos:scopeNote "If a Dataset is used as part of a Dataset Series, the usage of the properties listed below must be coherent with the associated Dataset Series. For this usage, consult the guidelines in section 14. General usage guidelines."@en;
dsv:reusesPropertyValue [
a dsv:PropertyValueReuse;
dsv:reusedProperty skos:prefLabel;
dsv:reusedFromResource <https://mff-uk.github.io/specifications/dcat-dap#Dataset>
].
We continue the example with the Dataset reuse as specified in the DCAT Default Application Profile. We can see that it reuses title and definition from the class dcat:Dataset in the DCAT vocabulary.
:Dataset dct:isPartOf <https://mff-uk.github.io/specifications/dcat-dap#>;
a dsv:TermProfile, dsv:ClassProfile;
dsv:class <http://www.w3.org/ns/dcat#Dataset> ;
dsv:reusesPropertyValue [
a dsv:PropertyValueReuse;
dsv:reusedProperty skos:prefLabel;
dsv:reusedFromResource <http://www.w3.org/ns/dcat#Dataset>
], [
a dsv:PropertyValueReuse;
dsv:reusedProperty skos:definition;
dsv:reusedFromResource <http://www.w3.org/ns/dcat#Dataset>
].
This gives us a term reuse hierarchy - Dataset in DCAT-AP reuses Dataset in DCAT-DAP, which, in turn, reused Dataset as defined in the DCAT vocabulary.
