Which version of the json-ld library is riot using? I was trying to use the "Document Base as the Default Vocabulary" as described in the json-ld specs [1], but I get an error:
$ riot --syntax jsonld --validate data.json ERROR riot :: invalid vocab mapping: @value must be an absolute IRI I'm using riot 3.9.0 $ riot --version Jena: VERSION: 3.9.0 Jena: BUILD_DATE: 2018-09-28T17:15:32+0000 RIOT: VERSION: 3.9.0 RIOT: BUILD_DATE: 2018-09-28T17:15:32+0000 ---- [1] https://json-ld.org/spec/latest/json-ld/#using-the-document-base-as-the-default-vocabulary
