hmm, ok, so one could assume that it works analogously for the

http://<stanbol>/rules/find/recipes?name=http://www.dfki.de/mere01/recipe/r2
I get a 404 Not Found.
(for a recipe named 'r2', created by
curl -i -X PUT

)
what am I doing wrong?
Nothing, except for assuming (with good reason) that it worked exactly
the same. The rules/find/recipes resource does not support the "name"
parameter at present, it only supports "description".
This means that if you want a recipe to be found, it must have been
created with a comment, such as
curl -i -X PUT
http://lnv-89012.dfki.uni-sb.de:9001/rules/recipe/http://www.dfki.de/mere01/recipe/r2?description=Test%20recipe
(not sure what happens with the URLencoded value for "description", though)
then
curl -H "Accept: text/turtle"
http://lnv-89012.dfki.uni-sb.de:9001/rules/find/recipes?description=est
Sorry for not finding this out earlier and misleading you.
Also: How do we then remove rules from a recipe, if we cannot address
them simply by attaching their URI or name to the endpoint's URL?
(again by checking the code) The recipe/rule path is currently in the form
/rules/recipe/{recipeId}?rule={ruleId}
and the DELETE works the same way, depending on "rule" having a value or
not.
It might be better to have something like
/rules/recipe/{recipeId}/{ruleId}
but before that we should make sure that recipeId allows simple non-URI
identifiers and refactoring works with non-URIs (which maybe now does).
And one more: For the refactoring functionality I didn't get very far.
First thing I wanted to give some minimal toy RDF graph as an input
and refactor via the RESTful Interface. This gives me the (not very
informative) message:
"The site <stanbol> says: Error".
(in the form of an alert window). This error might be due to virtually
anything. My toy example is
<?xml version="1.0" encoding="UTF-8"?>
<rdf:RDF
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#";
xmlns:dbpedia="http://dbpedia.org/property/";>
<rdf:Description rdf:about="urn:example:person:ernie">
<dbpedia:Person>Ernie</dbpedia:Person>
<dbpedia:profession>Friend of Bert</dbpedia:profession>
</rdf:Description>
</rdf:RDF>
and I was hoping for something like an application of the
"peopleProfessionRule" rule or something. (I already checked on
http://www.w3.org/RDF/Validator/ to make sure it is well-formed).
Here you're entering a realm I know even less, so I'm afraid I'm going
to need some more info.
What does the rule look like? Remember with that RDF there (with literal
triples / datatype assertions in OWL) the rules must be of the form
values() instead of has()
Did you use an HTML interface somewhere? Seems like the refactor
endpoint doesn't have one at the moment. Did you try it through the
tutorial in the /rules endpoint?
What response did you get by issuing the equivalent request to /refactor
via curl?

You can also ask for:
text/turtle
text/owl-manchester
text/owl-functional
application/owl+xml
application/rdf+json
Theoretically, it should also support
application/json (JSON-LD)
text/plain
but I don't see a body writer registered with rule lists so it didn't
work for me.
Best,
Alessandro
To check if it has been stored (and therefore parsed), you can do a
GET on
http://[stanbol]/rules/recipe/http://www.dfki.de/mere01/recipe/r1
requesting text/plain or some KR format such as
text/turtle
application/rdf+xml
text/owl-manchester
Hope this helps,
Alessandro
