11 years ago Conceptually, a dictionary has a logical structure consisting of key-value pairs.
This structure is often referred to as a mapExample (with some of my added comments):
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix owl: <http://www.w3.org/2002/07/owl#> .
@prefix prov: <http://www.w3.org/ns/prov#> .
@prefix : <http://example.com/> .
:our-old-baseball-team-field-positions
a prov:Dictionary,
:FieldPositions;
prov:hadDictionaryMember [ # I think we should just reuse prov:hadMember here.
a prov:KeyValuePair;
prov:pairKey "first-baseman"^^xsd:string; # No real need to type this.
prov:pairValue :george; # This could have been handled with prov:entity,
# if prov:qualifiedMembership had survived.
],
prov:hadDictionaryMember [
a prov:KeyValuePair;
prov:pairKey "pitcher"^^xsd:string;
prov:pairValue :carl;
];
.
:george a prov:Entity .
:carl a prov:Entity . Some trimming:
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix owl: <http://www.w3.org/2002/07/owl#> .
@prefix prov: <http://www.w3.org/ns/prov#> .
@prefix : <http://example.com/> .
:our-old-baseball-team-field-positions
a prov:Dictionary,
prov:hadMember [
a prov:KeyValuePair;
prov:pairKey "first-baseman";
prov:pairValue :george;
], [
a prov:KeyValuePair;
prov:pairKey "pitcher";
prov:pairValue :carl;
];
.
:george a prov:Entity .
:carl a prov:Entity . It would have been nice if they reused the qualification pattern:
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix owl: <http://www.w3.org/2002/07/owl#> .
@prefix prov: <http://www.w3.org/ns/prov#> .
@prefix : <http://example.com/> .
:our-old-baseball-team-field-positions
a prov:Dictionary, prov:Collection;
prov:hadMember :george, :carl; # Completely aligned with prov:Collection tooling.
prov:qualifiedMembership [
a prov:KeyValuePair;
prov:pairKey "first-baseman";
prov:entity :george; # Reused from qualification pattern.
], [
a prov:KeyValuePair;
prov:pairKey "pitcher";
prov:entity :carl; # Reused from qualification pattern.
];
.
:george a prov:Entity .
:carl a prov:Entity .
