An object can be any type of value -- it doesn't have to be an IRI. This might work:
import module namespace sem = "http://marklogic.com/semantics"; at "/MarkLogic/semantics.xqy”; sem:rdf-insert( ( sem:triple( sem:iri("http://example.com/ns/blue/154397";), sem:iri("http://example.com/ns/rankset/1443192107";), 141 ) ) -- Dave Cassel<http://davidcassel.net>, @dmcassel<https://twitter.com/dmcassel> Technical Community Manager MarkLogic Corporation<http://www.marklogic.com/> http://developer.marklogic.com/ From: <[email protected]<mailto:[email protected]>> on behalf of b <[email protected]<mailto:[email protected]>> Reply-To: MarkLogic Developer Discussion <[email protected]<mailto:[email protected]>> Date: Tuesday, October 20, 2015 at 10:45 AM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: [MarkLogic Dev General] Specific data types in sam:triple I’ve inserted a bunch of triples using code similar to this below. import module namespace sem = "http://marklogic.com/semantics"; at "/MarkLogic/semantics.xqy”; sem:rdf-insert( ( sem:triple( sem:iri("http://example.com/ns/blue/154397";), sem:iri("http://example.com/ns/rankset/1443192107";), sem:iri("http://example.com/ns/rank/141";) ) I change the document and the rank. Now, I want to retrieve it using SPARQL PREFIX rankset: <http://example.com/ns/rankset/<http://example/ns/timestamp/>> SELECT ?doc ?rank WHERE { ?doc rankset:1443192107 ?rank } ORDER BY ASC(?rank) LIMIT 250 And I get back things like this: 1 {"doc":"<http://example.com/ns/document/blue/134215>","rank":"<http://example.com/ns/rank/1>"}, 2 {"doc":"<http://example.com/ns/document/blue/144461>","rank":"<http://example.com/ns/rank/10>"}, 3 {"doc":"<http://example.com/ns/document/blue/140087>","rank":"<http://example.com/ns/rank/100>"}, 4 {"doc":"<http://example.com/ns/document/blue/150452>","rank":"<http://example.com/ns/rank/10000>"}, 5 {"doc":"<http://example.com/ns/document/blue/136182>","rank":"<http://example.com/ns/rank/101>"}, 6 {"doc":"<http://example.com/ns/document/blue/144417>","rank":"<http://example.com/ns/rank/102>”}… This is almost right. My value for rank is being treated like a string so I’m getting a string sort on the value. You can see this in line 5 and line 6 coming after line 4 above. Is there a way to coerce in SPARQL or should I correct the triple with some ata type declaration? How would that change my XQuery example above? I can’t find any examples of data types using the sem:triple. I have seen some in pure inline XML. Thank you bek
