Referencing individuals with Fuseki

Dear all,

I would like to use Fuseki in a linked data project. Is it possible to reference a single individual with a URI? For instance something like:

http://my.fuseki.server/datasetX#individualA

The link above currently returns the full dataset, even if the individual name is incorrect.

Thank you.

That is because the fragment isn't sent over HTTP.

You request is http://my.fuseki.server/datasetX

The URLs name the dataset and possible graphs within the dataset (GSP 
direct naming)

To get an individual:

DESCRIBE <http://my.fuseki.server/datasetX#individualA>


SELECT * { <http://my.fuseki.server/datasetX#individualA> ?p ?o }

because you want to read within the data.

An LDP (e.g. TrellisLDP) system does have this kind of individual naming 
- if you don't use "#individualA" but
http://my.ldp.server/path/individualA
