DCTERMS.format not working

[nicholascar]

When using the inbuilt DCTERMS namespace, from rdflib.namespace import DCTERMS, an error is thrown if the following triple is added to a graph:

g.add((r, DCTERMS.format, Literal('application/pdf')))

error: AssertionError: Predicate <built-in method format of Namespace object at 0x10e8e2de0> must be an rdflib term

Presumably there's a Python reserved word 'format' collision somewhere.

Have to do this as a workaround:

g.add((r, URIRef('http://purl.org/dc/terms/format'), Literal('application/pdf')))

Does DCTERMS['format'] work?

Oh, I think it does. And, I think I’ve even used it in the past...

Happy to have this issue closed as it’s really, really minor unless someone’s really keen to deal with it for fun.

I'm closing my own issue here as it's very minor and two work-around are given in comments.
