In a project we see 2 options of modelling the rule based knowledge.
1. Using shacl
Model the rule in shacl-af (if a and b then c)
1. Model the rule as metadata as kind of reference data fact (a,b,c)
involving a (one, generic) metarule in shacl-af selecting the apporriate fact
(just fyi
adam-shape:TemplateToInferMaatregelComplex a sh:NodeShape ;
sh:targetClass adam-o:Maatregel ;
sh:rule [
a sh:SPARQLRule ;
sh:prefixes adam-p:, adam-ex:, rdf: ;
sh:construct """
CONSTRUCT {
$this ?p ?o .
}
WHERE {
$this rdf:type
?type .
FILTER
(!STRSTARTS(STR($this),STR(adam-ex:))).
?bouwdeel_instance adam-p:heeftMaatregel $this .
?bouwdeel_instance rdf:type ?bouwdeel_type .
?bouwdeel_instance adam-p:heeftMateriaal ?bouwdeel_materiaal .
?ref_mat
rdf:type ?type .
FILTER
(STRSTARTS(STR(?ref_mat),STR(adam-ex:))).
?ref_bouwdeel
adam-p:heeftMaatregel ?ref_mat .
FILTER
(STRSTARTS(STR(?ref_mat),STR(adam-ex:))).
?ref_bouwdeel
rdf:type ?bouwdeel_type .
?ref_bouwdeel
adam-p:heeftMateriaal ?bouwdeel_materiaal .
?ref_mat ?p ?o .
}
"""
] .
Working on metadata like:
ex:Goed_Reling_2_with_two_Maatregels
rdf:type adam-o:Reling ;
adam-p:heeftMaatregel ex:Goed_ConserveringOverlagen_2 ;
adam-p:heeftMaatregel ex:Goed_GrootOnderhoud_3 ;
adam-p:heeftMateriaal adam-vwl:Staal ;
adam-p:oppervlakte "110"^^xsd:decimal ;
.
)
Now question is: what is best, futureproof option (well assuming the shacl-af
will be a recommendationanyway).
Option 1 seems more standard. Option 2 more particular but involving an an
efficient meta-rule as kind of template-rule.
Can you think of any pros/cons that can help us decide?
Thx a lot, Michel
