Perhaps a better thing to do than require further properties/constrains on `accessURL` would be to allow for the qualification of a more generic URL property for things in DCAT and then have as two specialisations equivalents to `dcat:downloadURL` & `dcat:accessURL`. This would allow for both backwards compatibility and also for further subclassing/vocabularisation to cater for more cases.
ISO19115-1 has a `DS_OnlineFuctionCode` which can be used to categorise links for a dataset, for example a `download`, `search` or `fileAccess` link. We could include/go beyond those various categories by including/extending those terms in a URL usage type vocab.
The Geoscience Australia profile of the ISO19115-1 standard (<http://pid.geoscience.gov.au/def/schema/ga/ISO19115-1-2014>) extends the normal code list to include a `provenanceQueryService` type link which is to be interpreted as a link to a PROV query service, as per [PROV-AQ:query service](https://www.w3.org/TR/prov-aq/#provenance-query-services) relevant to the dataset.
```
:DatasetX dcat:distribution [
dcat:qualifiedURI [
a dcat2:QualifiedURI ;
prov:role xxx:DownloadURI ;
dcat2:hasURIValue <http://something.com/getdata/1234> ;
] ;
dcat:qualifiedURI [
a dcat2:QualifiedURI ;
prov:role xxx:ProvenanceQueryService;
dcat2:hasURIValue <http://something.com/queryservice?dataset=1234> ;
]
]
```
