Hi,
Fuseki 2.3.0 doesnt seem to return prefixes and namespaces from
text:TextDataset with graph protocol. You would expect that these return the
same result:
Hi Miika,
I tried your example and it works for me.
If you loaded from N-triples or with a bulk loader there aren't any
prefixes (the bulk loaders do now, post the last releases, save the
prefixes).
IIRC CONSTRUCT gets its prefixes from the query.
GET /textDataset?default HTTP/1.1
which does not agree with the configuration below ...
The form "/dataset?default", directly using the graph store protocol on
the dataset, rather than "/dataset/data?default", got fixed recently
(post the last releases). That might accoutn for twhat you are seeing
(if it worked at all).
Andy
Host: localhost:3030
Accept: text/turtle; charset=utf-8
and
CONSTRUCT { ?s ?p ?o } WHERE { ?s ?p ?o }
but graph protocol from TextDataset returns expanded content (without prefixes
and namespaces), while CONSTRUCT queries returns compact data with prefixes and
namespaces.
I'v tried couple of configurations with the same result and it doesnt seem to
matter if the TDB dataset is called trough separate service. Am i missing
something or is this a bug or a feature? :)
So directly on the TDB service, no text dataset, also does not have
prefixes? See above - looks like there aren't any loaded.
My current "simplified" configuration is:
