Neosemantics only /rdf/ping works

[thomas_stuempfi]

Hi all,
i try to use neosemantics. In one of my db it works fine. Both procedures and extensions /rdf/

in an other one only the semantics.* procedures and :get /rfd/ping works. no other url seems to work.

i am more than welcome for any idea.

regards
Thoams

Hi Thoams,

What version(s) of Neo4j and neosemantics do you have for your databases?

Kind regards,

Hi Lju,
thank you for the reply.
my versions are:
Neosemantics : neosemantics-3.4.0.2.jar
Neo4J
Version: |3.4.0|
Edition: |enterprise|

searched further in the internet updated my neosemantics library and found a different tutorial
( https://jbarrasa.com/2018/10/18/quickgraph7-creating-a-schema-org-linked-data-endpoint-on-neo4j-in/
) where some urls seem to work

:POST /rdf/cypher { "cypher" : "MATCH (n:BusinessObject) return n limit 25" } worked ok now.

whereas
:get /rdf/describe/id/4444 does not (it does in my other database)
:GET /rdf/describe/id?nodeid=5555 does.

so it seems that the documentation i was reading did not reflect the version i use.

The only thing left that i am looking for is how to specify the output format. I always get ttl no json-ld
specifying "format":"JSON-LD" did not help.

Best regards
Thomas

addition

:GET /rdf/onto
does not work
"could not fetch URL: "404 Not Found". This could be due to the remote server policy. See your web browsers error console for more information."

Hi Thomas,

There have been breaking changes in the latest version and most of the methods in the extension have changed to /rdf/. The new manual for this is available from: http://jbarrasa.github.io/neosemantics/

I hope this helps!

Kind regards,

Lju

This error occurred when exporting RDF from Neo4J. Any suggestions?

Could not fetch URL: "Failed to fetch". This could be due to the remote server policy. See your web browsers error console for more information.
