------------------------------
Summary: Provide better support for compressed input formats
Key: JENA-601
URL: https://issues.apache.org/jira/browse/JENA-601
Project: Apache Jena
Issue Type: Improvement
Components: RIOT
Affects Versions: Jena 2.11.0
Reporter: Rob Vesse
Currently Jena has little or not support for compressed input formats. There
are the odd cases where some consideration is given e.g.
- {{RDFLanguages.filenameToLang()}} strips off {{.gz}} extensions to help it
correctly detect file types
- HTTP responses can deal with compressed responses by virtue of Apache
HttpClient
What would be nice is to have a better strategy for handling compressed inputs.
For example having a registry of known compression extensions e.g. {{.gz}},
{{.bz2}}, {{.deflate}} which ARQ would strip off when trying to deduce format
from the filename.
It would also be useful if the various locator implementations took compression
into account when opening input streams as I'm fairly sure if you asked ARQ to
open a {{foo.nt.gz}} file it would just open a raw input stream and then the
reading would fail.
