I managed to get a fresnel result tree by calling:
Selection selected = conf.select(dataRepo);
But the results are somehow unpredictable and depend on the order of lenses
in my fresnel.n3 .
So I'm trying to get the resources that I want by calling the select
function with a Resource and a Group:
****************************************************************************
// generate output Document
Selection selected = conf.select(
dataRepo,
new
URIImpl("http://www.polowinski.de/ontologies/History.owl#Event";),
new Group(new
URIImpl("file:///C:/EigeneDateien2/Projekte/FresnelSubversionProject/data/te
stJan/fresnel.n3#eventGr"))
);//, (Resource)obj);
selected = conf.format(dataRepo, selected);
****************************************************************************
But now the engine says:
****************************************************************************
edu.mit.simile.fresnel.configuration.NoResultsException: No results from
selection: No lenses matching the data could be found.
at
edu.mit.simile.fresnel.configuration.Configuration.select(Configuration.java
:770)
[...]
****************************************************************************
I debugged it and unfortunately found everything as I expected it.
The Resource has the uri
"http://www.polowinski.de/ontologies/History.owl#Event";
The Group has the Resource_identifier with uri
"file:///C:/EigeneDateien2/Projekte/FresnelSubversionProject/data/testJan/fr
esnel.n3#eventGr" (is it okay, to have a file reference here?)
And the Sails MemStatementsList of the Repository seems to contain my
instances of ".../History.owl#Event"
Here is my fresnel configuration file:

What could be my mistake? Maybe I can find a working example like this
somewhere? The tests in the fresnel test folder don't make use of
select(Repository, Resource, Group).
Thank you for any help with this and for reading this long post - in case I
should understand it I'm willing to add my experiences to the WIKI... ;)
