Hello Suat,
thanks for your help. I updated and rebuilt the contenthub today, but
it seems I still can't get through with the DELETE. When trying to
delete a content item, the preflight keeps returning only GET, POST
and OPTIONS to me as the allowed methods.

and when trying to delete an Index, I get '204 Not Content' and the
response header looks pretty strange:

Do I need to update something else apart from the contenthub?
As to submitting new indices, I'm a bit confused now. When submitting
an ldpath program via the web interface, a Form Data object seems to
be used to carry the data:
1.
1. Form Dataview URL encoded
1.
name:
melaniesIndex
2.
program:
@prefix rdf : <http://www.w3.org/1999/02/22-rdf-syntax-ns#>;
@prefix rdfs : <http://www.w3.org/2000/01/rdf-schema#>; @prefix
db-ont : <http://dbpedia.org/ontology/>; title = rdfs:label ::
xsd:string; dbpediatype = rdf:type :: xsd:anyURI; population =
db-ont:populationTotal :: xsd:int;
But anyway, the curl -d works as you say and I could also implement it
for the XmlHttpRequest.
Best,
melanie

Hi Alessandro, Melanie,
@Alessandro, thanks for the answer.
@Melanie, to be able to submit an LDPath program, the correct usage with
curl are is follows. Currently, this endpoint does not support sending
requests with (form-multipart) objects.
curl -i -X POST -d "name=melaniesIndex&program=@prefix rdf :
<http://www.w3.org/1999/02/22-rdf-syntax-ns#
<http://www.w3.org/1999/02/22-rdf-syntax-ns#>>; @prefix rdfs :
<http://www.w3.org/2000/01/rdf-schema#
<http://www.w3.org/2000/01/rdf-schema#>>; @prefix db-ont :
<http://dbpedia.org/ontology/>; title = rdfs:label :: xsd:string;
dbpediatype = rdf:type :: xsd:anyURI; population =
db-ont:populationTotal :: xsd:int;"

Also, I fixed the CORS support issues you mentioned. Please let me know
if you have any other problems.
Best,
Suat

Hi Melanie,
I can see that path has a preflight handling function, so it should
support CORS.
However it doesn't specify the allowed methods. Perhaps the line
enableCORS(servletContext, res, headers);
should be
enableCORS(servletContext, res, headers, GET, POST, DELETE, OPTIONS);
like I had to do for the ontologymanager endpoint to work?

Hi Rupert, Alessandro.
Is it possible that we still do not have CRUD access on the
contenthub?
When doing a DELETE on
<stanbol>/contenthub/contenthub/store/<itemID>,
I'm getting
Access-Control-Allow-Methods: GET, POST, OPTIONS
as response to the preflight request (so DELETE would be missing
then).
The same problem for
<stanbol>/contenthub/ldpath/program/<indexID>.
When trying to create an index by sending a FormData object
(form-multipart) to contenthub/ldpath/program, my request gets stuck.
I can't even get through with curl:
curl -i -X POST -F 'name=melaniesIndex' -F "program='@prefix rdf :
<http://www.w3.org/1999/02/22-rdf-syntax-ns#>; @prefix rdfs :
<http://www.w3.org/2000/01/rdf-schema#>; @prefix db-ont :
<http://dbpedia.org/ontology/>; title = rdfs:label :: xsd:string;
dbpediatype = rdf:type :: xsd:anyURI; population =
db-ont:populationTotal :: xsd:int;'"
http://<stanbol>/contenthub/ldpath/program
I get Unsupported Media Type error. I guess there's some issue with
the @ symbols in the program (normally they are used to reference
files), but escaping them was of no use.
And one more minor thing:
For
curl -i -X DELETE <stanbol>/contenthub/ldpath/program/melaniesIndex
I get
HTTP/1.1 200 OK
Content-Length: 0
Server: Jetty(6.1.x)
even if the index does not exist any more (i.e., if it has been
deleted before).
