But what if I want to query against multiple values? Let’s start with some sample data. ‘use strict’; declareUpdate(); const sem = require(“/MarkLogic/semantics”) const myPred = sem.iri(“myPredicate”); sem.rdfInsert([1, 2, 3, 4, […]

It turns out that approach doesn’t work for SPARQL Update. I’ll use the same sample data as my previous post: ‘use strict’; declareUpdate(); const sem = require(“/MarkLogic/semantics”) const myPred = sem.iri(“myPredicate”); sem.rdfInsert([1, 2, 3, 4, […]
