Andy Seaborne commented on JENA-127:
------------------------------------
Aside:
While it might be nice replace the whole way readers/writers get manged, and
the current one is a bit clunky, but things change so rarely that the effort to
redo is much greater than living with the current hardcoded system.
You can set the impl classname to null or "" to unset.
We've talked about this pre-Apache. If I find time I'll try to dig out any
email discussion from SF or if not, write-up a new one (interesting to compare
it to the old one if found).
> Add RDF/JSON Parsing Support to RIOT
> ------------------------------------
>
> Key: JENA-127
> URL: https://issues.apache.org/jira/browse/JENA-127
> Project: Jena
> Issue Type: New Feature
> Components: ARQ, Jena, RIOT
> Environment: All
> Reporter: Rob Vesse
> Assignee: Paolo Castagna
> Priority: Minor
> Labels: patch, rdf/json, riot
> Attachments: ARQ_JENA-127_r1179358.patch, JenaReaderRdfJson.java,
> LangRDFJSON.java, RdfJsonRiotPatch-ApacheSVN.patch, RdfJsonRiotPatch.patch,
> RdfJsonRiotPatch.patch, TestLangRdfJson.java, TestLangRdfJson.java
>
>
> The attached patch provides a RDF/JSON (Talis Specification) parser for RIOT,
> the patch is against ARQ trunk from the Jena SourceForge SVN repository
> It plugs in as an implementation of LangRIOT (named LangRDFJSON) and uses the
> existing TokenizerJSON from the atlas package to do the tokenisation. There
> is also a JenaReaderRdfJson added as part of this patch which does what the
> name suggests.
> I have also included in this patch a set of unit tests which verify the
> parsers behaviour with a variety of valid and invalid inputs.
> There are still some things to be addressed:
> - The patch includes registration of the Jena reader when
> SysRiot.writeIntoJena() is called but does not unregister itself when
> resetJenaReaders() is called, should this be done?
> - Add a RDF/JSON writer - a separate patch will be submitted at a later date
> (likely next week) for this
> Otherwise the patch is fairly comprehensive and I hope can be reviewed and
> included in future releases
> EDIT - I have now redone the patch against Apache SVN as well and attached
> that as a separate file since there are some differences in the structure of
> the two repos and some minor code changes that mean the SourceForge SVN patch
> cannot be applied directly against Apache SVN
