Hi Michael

"application/rdf+xml" is the correct content type. I tend to use "-T {file}"
instead of "--data "@{file}" but this should make no difference based on the
man page of curl.
However in general this method is intended to create a single (or small amount
of) entities. It is not intended to be used with RDF data that include 25k+
Entities like the NCI ontology because it
1) loads everything into memory
2) stores and commits every single entity
Note that the HTTP request will timeout after one minute (curl will print
"curl: (52) Empty reply from server"), but the actual import will take much
longer. However you can use the Entityhub normally while the data are imported.
Using the Indexing utilities (as already described by Suat) would be the
preferred way to "teach Stanbol cancer".

I think this is related to https://issues.apache.org/jira/browse/STANBOL-519
which is resolved in the meantime. So if you "svn update" and than "mvn clean
install" this problem should be gone.
I am running the newest Stanbol version on my local machine. Uploading the
"nciOncology.owl" with the above curl request runs now since about 20min and is
has not yet completed.
However the request
url -H "Accept: application/rdf+xml"
http://localhost:8080/entityhub/entity?id=http://www.mindswap.org/2003/nciOncology.owl#High-Grade_Mucoepidermoi_Breast_Carcinoma
succeeds and provides the expected results
