Is it possible to use prefixes with templates? #115

Closed paulakeen closed 3 years ago

paulakeen commented 3 years ago

When working with turtle serialisations, it would be great if it was possible to replace the URI of the subject template with its prefix. But I couldn't work it around. Is this even possible in RML? Tks.

Could you provide a minimal example, just to make sure we're on the same page? :)

For example, we'd like to have an outcome of the type:

@prefix foaf: <http://xmlns.com/foaf/0.1/> .
@prefix ex: <http://example.org#> .

ex:paula a foaf:Person ;
foaf:givenName "Paula" ;
foaf:familyName "Keen" .

instead of:

@prefix foaf: <http://xmlns.com/foaf/0.1/> .
@prefix ex: <http://example.org#> .

<http://example.org#paula> a foaf:Person ;
foaf:givenName "Paula" ;
foaf:familyName "Keen" .

instead of

As far as I know, this is out of scope of [R2]RML. Instead, I created a new issue in the mapping challenges repository of the Knowledge Graph Construction Community Group: kg-construct/best-practices#5

I'm afraid there's no other solution right now except for post-processing the output.
