Rob Vesse created JENA-600:
------------------------------
Summary: Fuseki Upload does not support compressed data e.g. GZip
Key: JENA-600
URL: https://issues.apache.org/jira/browse/JENA-600
Project: Apache Jena
Issue Type: Bug
Components: Fuseki
Affects Versions: Fuseki 1.0.0
Reporter: Rob Vesse
Assignee: Rob Vesse
Fix For: Fuseki 1.0.1
If you want to upload a large file to Fuseki it would be nice if it supported
compressed data formats such as GZip.
Currently trying to upload a GZipped file results in the following:
{noformat}
13:00:01 INFO Fuseki :: [1] POST http://localhost:3030/ds/upload
13:00:01 INFO Fuseki :: [1] Upload: Filename:
med-triangles.nt.gz, Content-Type=application/x-gzip, Charset=null => N-Triples

It should be possible to determine the appropriate type by examining the file
extension of the attachments and then open an appropriate GZip stream over the
uploaded data stream.
I'm gonna take a look at doing this later today.
