Can you please describe what you’re doing to get this error? Running a query? Parsing a file (rdf or query result)? Something else? Example data or code would be helpful in understanding the issue.
Parsing a file. I think this turtle will do it.
urn:uuid:8f340231-f5d4-4886-be63-c1f1b5c1ca77 a
urn:uuid:8f340231-f5d4-4886-be63-c1f1b5c1ca77
This is not valid turtle. The urn IRIs should use <> quoting. As it is, the urns are being interpreted as prefix names that are using the “urn:” prefix, but no corresponding prefix declaration is found.
Sorry about that, my bad!
No worries!
A URL like
urn:uuid:8f340231-f5d4-4886-be63-c1f1b5c1ca77
(which is the result of the sparqluuid()
function) causes this error:Use of undeclared prefix 'urn' at 66:1 (near 'urn:')
