Hi Stanbol people,
I have a few questions concerning the cmsadapter.
1)
To map a content repository to an RDF graph,
curl -i -X POST -d
"sessionKey=eec8ff46-aaf9-485f-a7b5-452c1d7197d0&baseURI=[some_uri]&store=true"
http://[stanbol]/cmsadapter/map/cms
does not work for me. (I get 500 internal server error)
Maybe the logs may indicate something.
log is:
13.08.2012 13:43:26.423 *WARN* [30251362@qtp-23261232-111]
org.apache.stanbol.cmsadapter.jcr.mapping.JCRRDFMapper Failed to
retrieve node having path: /rdfmaptest or its children
ok, so I need to configure the path.
In any case, I guess that you
need to configure a RDF Bridge through the
{stanbol}/system/console/configMgr interface. There you should find the
"Apache Stanbol CMS Adapter Default RDF Bridge Configurations". In that
configuration you specify the root path in the CMS to be exported to the
RDF.
by that you mean the content repository path? This means that I set
there the path to my content repository? I have set up a jackrabbit
workspace with some toy nodes in it. To access it remotely, I'd
configure something like http://[myserver]/server/
<http://lnv-89012.dfki.uni-sb.de:9002/server/default/node1>, but then I
can work with this repository exclusively, right?
The documentation says:
*"baseURI*is a mandatory parameter that is used as the base URI of the
RDF to be generated."
Why is this baseURI needed here as mandatory parameter, if the RDF
graph is returned to the user in application/rdf+xml format?
And what can I specify as baseURI (does it work with a local file path
or directory path)?
You should be able to specify any URI for the base URI. While
transforming the nodes to RDF, corresponding rdf:resources are
identified by appending the identifiers of the nodes to the baseURI e.g.
<rdf:Description
rdf:about="http://www.apache.org/stanbol/cms#432271b6-80a5-41e9-89c0-bc8623c1ad97";>
....
2)
For the contenthubfeed, I wanted to submit a content item with path
'node1/node2' from my repository with:
curl -i -X POST --data
"sessionKey=5d934b53-dc33-4d9c-884f-c16c8ba872af&path=/node1/node2&recursive=true"
http://lnv-89012.dfki.uni-sb.de:9001/cmsadapter/contenthubfeed
I get 200 OK, but when I look on the contenthub, nothing has changed,
no new items are listed.
Would it notify me in case it cannot find my repository item (e.g. for
wrong name or wrong path)?
This can be seen from the logs.
ok, it couldn't resolve the path:
13.08.2012 13:43:32.576 *WARN* [30251362@qtp-23261232-111]
org.apache.stanbol.cmsadapter.jcr.mapping.JCRContenthubFeeder Failed to
obtain the item specified by the path: /node1/node2
javax.jcr.PathNotFoundException: /node1/node2
but that's also due to the wrong content repository path.

Considering the possibility of checking
multiple items when recursive=true, I had not passed the exception to
the client side. Maybe this should be improved...
Best,
Suat
(I was trying for JCR/RMI)
Thanks,
