Re: [DBpedia-discussion] Broken Turtle for David Bowie?

[Dimitris K. <ji...@gm...>]

Hi Paul, I think this is a serialization issue.
The IRI is valid as an IRI but cannot be prefixed in turtle. if it was
serialized as a full IRI it request would be valid.
Can you try to get it in another format like nt?
