It is also a stackoverflow question from yesterday. This is the 3rd one in a week (one was actually about another system anyway) calling something a bug that are really about how to use Jena. Questions are not bugs. Neither are they "urgent". Often, the questioner does not respond and we get floating JIRA issues. They aren't going to get answered on JIRA so I think we should quickly close them for fear of getting swamped, referring to them to users@ e.g. boiler plate like: ------------- Hi there, This is a question and is best sent to the Jena users mailing list. [email protected]. You need to subscribe first, then respond to the verification email, then send your question: For details: https://jena.apache.org/help_and_support/index.html ------------- Andy On 01/04/2020 10:01, David (Jira) wrote: > David created JENA-1876: > --------------------------- > > Summary: Parsing json-ld in Jena and type : rdfs:container does >not come through as a statement > Key: JENA-1876 > URL: https://issues.apache.org/jira/browse/JENA-1876 > Project: Apache Jena > Issue Type: Bug > Components: Base > Reporter: David > > > I have a jsonld file that I am parsing using Jena.
