Hi all,

I begin to try Clerezza with the rdf.core tutorial suggested by Tommaso.
As I read and try, I update the tutorial, you can find the associated patch here : https://issues.apache.org/jira/browse/CLEREZZA-234

Here comes some "problems" found during the tutorial. Suggestions welcomes.


*About slf4j : *
- version into the doc is 1.5.5, in central, there is now 1.6. Do you know with version is the most suitable for now ?

(works with 1.5.5)

*About mvn execution : *
- I have some problems for execute the created class with command line suggested in tutorial... - command line : mvn compile exec:java -Dexec.mainClass=org.example.clerezza.scb.tutorial1.App -e
- error : object is not an instance of declaring class
- full stack trace [1]

Do another try in eclipse and it's works, seems that eclipse use the mojoExecution resource:resource as parameter...

Any idea is welcome.

+ Error stacktraces are turned on.

Thanks Tommaso for all this useful links !

I will study them in details.

After a rapid read of Trialox tutorial, I see that this tutorials indicate
"old" Trialox repository : http://repo.trialox.org/release

As I will read this docu in details, I can provide an update patch for it.
But in that case, what is the better maven repos to indicate ? This :
https://repository.apache.org/content/groups/public/ ?

Thanks twice,
Have a good day.

  A/ How to use OpenCalais and AlchemyAPI services ?


There is the UIMA integration which uses AlchemyAPI and OpenCalais to
enrich
graphnodes, documentation still needs to be done, I'll do it as soon as
possible but firstly I think we need to write an ontology for generated
UIMA
entities (I am doing this at the moment but I think that if Oliver has
already something in place it would be nice to have a look) so that the
graph gets enrihced in a proper RDF way.

Take a look at this in the meantime:

http://svn.apache.org/repos/asf/incubator/clerezza/trunk/org.apache.clerezza.parent/org.apache.clerezza.uima/org.apache.clerezza.uima.metadata-generator/src/main/java/org/apache/clerezza/uima/metadatagenerator/UIMABaseMetadataGenerator.java
and at

http://svn.apache.org/repos/asf/incubator/clerezza/trunk/org.apache.clerezza.parent/org.apache.clerezza.uima/org.apache.clerezza.uima.utils/src/main/java/org/apache/clerezza/uima/utils/ExternalServicesFacade.java



  B/ How I can create / edit and try a graph in Clerezza ?


Still Triaxrs branded pages that contain such tutorials are:

http://incubator.apache.org/clerezza/mvn-site/org.apache.clerezza.rdf.core/documentation/overview.xhtml

http://incubator.apache.org/clerezza/mvn-site/org.apache.clerezza.rdf.core/documentation/tutorial_1.xhtml

http://incubator.apache.org/clerezza/mvn-site/org.apache.clerezza.rdf.core/documentation/scb-triaxrs-tutorial.xhtml

Cheers,
Tommaso
