Hey, Jena seems to use another DTD than the one hosted by W3C: https://www.w3.org/2004/03/trix/trix-1/trix-1.0.dtd vs. https://github.com/apache/jena/blob/master/jena-arq/src/main/java/org/apache/jena/riot/lang/TriX.java
>From the first glance, at least the root element differs: <trix> vs. <TriX>. The TriX namespace resolves to that DTD version, so I would expect it to be "standard": http://www.w3.org/2004/03/trix/trix-1/ As a result, we are getting parse errors when trying to read TriX that conform to W3C DTD: ERROR riot:84 - [line: 2, col: 54] Unrecognized XML element: trix Can we agree that the DTD should be fixed? I can make a pull request. Martynas atomgraph.com
