Formatters / DCAT-AP / Allow PO URI to be used for constraints.
Browse files Browse the repository at this point in the history
In DCAT-AP, the Publication Office vocabulary is used for license and the mapping was expecting ISO to encode original URI (eg. http://creativecommons.org/licenses/by/4.0/) and not PO ones (eg. http://publications.europa.eu/resource/authority/licence/CC_BY_4_0). So ISO record using PO URI was not returning the licence in DCAT-AP (and was in DCAT - because all licence URI are allowed).

The vocabulary is encoded with the following and `skos:exactMatch` was used for the mapping:
```xml

   <skos:Concept rdf:about="http://publications.europa.eu/resource/authority/licence/CC_BY_4_0"
                 at:deprecated="false">
...
      <skos:exactMatch rdf:resource="http://creativecommons.org/licenses/by/4.0/"/>
```

Adding also `rdf:about` to allow PO URI to be used in ISO record.

Eg. if
```xml
         <mri:resourceConstraints>
            <mco:MD_LegalConstraints>
               <mco:useConstraints>
                  <mco:MD_RestrictionCode codeList="http://standards.iso.org/iso/19115/resources/Codelists/cat/codelists.xml#MD_RestrictionCode"
                                          codeListValue="otherRestrictions"/>
               </mco:useConstraints>
               <mco:otherConstraints>

                                          codeListValue="license"/>
               </mco:useConstraints>

```

DCAT-AP (only allow PO URI)
```xml
