Gilles Sérasset commented on JENA-601:
--------------------------------------
Would it be possible to add support for other formats (e.g. bzip2) that are
available using common compress ?
> 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
> Priority: Major
>
> 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.
