preserve `base` on output

[VladimirAlexiev]

SA works perfectly!

• Take this genericode XML http://www.ebiz.enea.it/moda-ml/repository/codelist/v2018-1/gc_NT11.xml.
• To convert to basic SKOS, I use this short query

base         <https://cirpass.eu/thesauri/>
prefix xyz:  <http://sparql.xyz/facade-x/data/>
prefix fx:   <http://sparql.xyz/facade-x/ns/>
prefix rdf:  <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
prefix skos: <http://www.w3.org/2004/02/skos/core#>

construct {
  $_thes_iri skos:member ?item.
  ?item a skos:Concept; skos:notation ?code; skos:prefLabel ?label.
}
where { service <x-sparql-anything:>
  { fx:properties fx:location $_location.
    ?row a xyz:Row;
      rdf:_1 [xyz:ColumnRef "code"; rdf:_1/rdf:_1 ?code];
      rdf:_2 [xyz:ColumnRef "EN";   rdf:_1/rdf:_1 ?label]
  }
  bind(iri(concat(str($_thes_iri),"/",?code)) as ?item)
}

• and this command line:

sparql-anything -v location=eBIZ-NT11.xml -o eBIZ-NT11.ttl -v thes=inventory/reason/transport -q eBiz.rq

The only comlpaint I have is that the result uses full URLs:

<https://cirpass.eu/thesauri/inventory/reason/transport/FOC>
        rdf:type        skos:Concept;
        skos:notation   "FOC";
        skos:prefLabel  "free of charge" .

<https://cirpass.eu/thesauri/inventory/reason/transport>
        skos:member  <https://cirpass.eu/thesauri/inventory/reason/transport/WRK> , <https://cirpass.eu/thesauri/inventory/reason/transport/VEW> , <https://cirpass.eu/thesauri/inventory/reason/transport/STO> , <https://cirpass.eu/thesauri/inventory/reason/transport/SEL> , <https://cirpass.eu/thesauri/inventory/reason/transport/RJC> , <https://cirpass.eu/thesauri/inventory/reason/transport/NWK> , <https://cirpass.eu/thesauri/inventory/reason/transport/IST> , <https://cirpass.eu/thesauri/inventory/reason/transport/FWK> , <https://cirpass.eu/thesauri/inventory/reason/transport/FVW> , <https://cirpass.eu/thesauri/inventory/reason/transport/FST> , <https://cirpass.eu/thesauri/inventory/reason/transport/FRW> , <https://cirpass.eu/thesauri/inventory/reason/transport/FOC> .

https://tarql.github.io/ (also Jena based) has this option:

 --write-base           Write @base if output is Turtle

It allows the production of much shorter turtles. Unfortunately Tarql doesn't remember the base in the query, so one also needs to give

      --base                 Base IRI for resolving relative IRIs

Can SA remember the base and use it in the output?

What happens if you add to the query:

PREFIX thes: <https://cirpass.eu/thesauri/inventory/reason/transport/>

?

I'm sure it will use it, but

• that prefix is useful only for -v thes=inventory/reason/transport
• a complex script will typically emit in numerous instance subspaces, should we define prefixes for all of them?
