…Is to produce full URIs. Previously rdf:about elements contained not a full URI, like rdf:about='353108a0-f0f8-4f8e-9d0e-60f18dfda169' that was causing validation issues in DCAT-AP validator

Previously language codes were inconsistent, these type of elements got the language iso3 codes (<dct:title xml:lang='dut'...) and elements from vocabularies, where the language is defined with the iso2 code, got the iso2 code: (<skos:prefLabel xml:lang='nl'...)
Otherwise the template for managing resource constraints in formatter/dcat/dcat-core-access-and-use.xsl did not correctly process the contraints when the first resource constraint had no access or use constraints. For example:
<mri:resourceConstraints>
<mco:MD_Constraints>
<mco:useLimitation>
<gco:CharacterString>Geen gebruiksbeperkingen</gco:CharacterString>
</mco:useLimitation>
</mco:MD_Constraints>
</mri:resourceConstraints>
<mri:resourceConstraints>
<mco:MD_LegalConstraints>
<mco:accessConstraints>
<mco:MD_RestrictionCode codeList=http://www.isotc211.org/2005/resources/Codelist/gmxCodelists.xml#MD_RestrictionCode codeListValue=otherRestrictions codeSpace=ISOTC211/19115>otherRestrictions</mco:MD_RestrictionCode>
</mco:accessConstraints>
<mco:otherConstraints>
<gco:CharacterString>Open data (publiek)|https://creativecommons.org/publicdomain/mark/1.0/deed.nl\</gco:CharacterString\>
</mco:otherConstraints>
</mco:MD_LegalConstraints>
</mri:resourceConstraints>

Improve the functions to obtain record / resource URIs to produce full URIs.
The original metadata can be ISO19115.3-2008 or ISO19139. For ISO19139, the extraction of languages was not defined.
Use iso2 language code for rdf localised elements and
adms:statusProcess all resource constraints.
Formatter / DCAT / EU / Fix conformsTo URI for DCAT-AP and add legislations.
Formatter / DCAT / Use relation API to populates link. Adds:
Formatter / DCAT / Service / Endpoint description can also be a link with function information.
Formatter / DCAT / Distribution
Formatter / DCAT / Avoid to generate URI not starting with http (which will be RDF invalid). Add missing match on online resource name and DQ citation link.
Formatter / DCAT / EU publication file type expect http URI not https. Also add additional iana types.
Formatter / DCAT / Limit dcat:theme element to EU data themes. Keywords are encoded using dct:subject if with Anchor and dcat:keyword for label.
Formatter / DCAT / EU validator complains about this.
Formatter / DCAT / Add ADMS license type and EU access rights.
Based on license URL add corresponding ADMS type
Based on accessConstraint type add EU access type
