optionaldatatype?:string
Datatype IRI, for a typed literal.
optionallang?:string
Language tag, for a language-tagged string (wire field xml:lang).
type:

Type Literal
Section titled “Type Literal”{ type: "triple"; value: SparqlTripleTermValue; }
type:

Remarks
Section titled “Remarks”A discriminated union over the RDF term kinds of the W3C
SPARQL 1.1 Query Results JSON Format,
discriminated by type: uri, literal, bnode, or (RDF 1.2) triple.
Only a literal carries datatype (typed literal) or lang (language-tagged
string); the wire form spells the language tag xml:lang and the normalizer maps
it to lang. A triple term’s value is the nested
SparqlTripleTermValue, not a lexical string.
This is NOT the tagged ValueDto / untagged FeatureValueDto Psi-term
serialization — SPARQL results carry RDF terms, a separate wire vocabulary.
Example
Section titled “Example”const iri: SparqlRdfTerm = { type: 'uri', value: 'http://example.org/alice' };const age: SparqlRdfTerm = { type: 'literal', value: '42', datatype: 'http://www.w3.org/2001/XMLSchema#integer',};const label: SparqlRdfTerm = { type: 'literal', value: 'Alice', lang: 'en' };
