Ajouter un paramètre pour contrôler le prédicat utilisé pour les types dans les requêtes (rdf:type / wdt:p31 pour Wikidata)

[tfrancart]

Wikidata (https://query.wikidata.org) n'utilise pas rdf:type pour déclarer l'information de type, mais un prédicat spécial, wdt:p31 (full URI <http://www.wikidata.org/prop/direct/P31>).

Il faut ajouter une option de config "typePredicate" pour contrôler l'identifiant utilisé pour construire les queries. Par défaut cela doit rester "rdf:type", mais on veut pouvoir l'overwriter avec la valeur 'http://www.wikidata.org/prop/direct/P31'.

Plus précisément, on va vouloir passer "wdt:P31/wdt:P279*"

@tfrancart hello! I've been trying to use type predicate to get the "http://www.wikidata.org/prop/direct/P279*" behaviour, but I could not find a way of implementing that in native Sparnatural.

If I set something like

        addDistinct: true,
        typePredicate: "http://www.wikidata.org/prop/direct/P279*",
        sendQueryOnFirstClassSelected: false,

The system will render <http://www.wikidata.org/prop/direct/P279*> instead of <http://www.wikidata.org/prop/direct/P279>*.

Any ideas on how to make it work? Thanks!!

Hi @lubianat, are you using version <8? I just noticed that this feature is missing in version >8. I can have a look at it

[lubianat]

I am not sure which version I am using, this is the repo: https://github.com/lubianat/cell_ontology_sparql

(I tried to find out which version, but could not find it)

[SteinerPascal]

Yes you are using the old version. I have a fix for the sparql property path (*) already but I will investigate more on how to cover the others as well (https://www.w3.org/TR/sparql11-query/#propertypaths).
But interesting question you raised here

[tfrancart]

Hmmm, this feature **is** in v8, see http://docs.sparnatural.eu/Javascript-integration#html-attributes-reference, "typePredicate" parameter, and https://github.com/sparna-git/Sparnatural/blob/1f2b07828e02933e747e4dc090ef60e1df95c36f/src/SparnaturalAttributes.ts#L6 @SteinerPascal, make sure you update your source code as I ported this right before publishing v8.

And right now you can't use a property path as a value of this parameter, just a predicate. Le mer. 18 janv. 2023 à 22:19, Thomas Francart ***@***.***> a écrit :

@tfrancart have you tested it? doesn't seem to work for me on main branch... also I can not see where it is integrated into the sparqlgenerator...

[tfrancart]

Ho yes, there is something wrong here. The parameter is passed down to RdfJsGenerator at https://github.com/sparna-git/Sparnatural/blob/master/src/sparnatural/generators/SparqlSelectBuilder.ts#L31, but never used. I will open a new issue.
And probably yes, using a property path here might not work now...

[SteinerPascal]

@lubianat As you can see i have a solution for any kind of property path for the type predicates. It should be merged into the main branch anytime soon.
