Rob Vesse commented on JENA-666:
--------------------------------
Andy
I have now updated all the copyright headers appropriately and stubbed out a
basic LICENSE and NOTICE
The primary dependency is just Apache Hadoop which is handled simply by
mentioning it in the NOTICE file I believe? Most of that is also marked as
provided as well since they'll be part of a Hadoop installation so if and when
we ever created convenience binaries this and their transitive dependencies
should not be an issue. Regardless anything that is a transitive dependency
via Apache Hadoop must be allowed in Apache distributions anyway or the Hadoop
PMC couldn't release it.
The demo app (hadoop-rdf-stats) uses airline
(https://github.com/airlift/airline) to provide the CLI and this is distributed
under the ALv2 so again I assume just a mention in NOTICE for that module is
appropriate?
> IP Clearance for Hadoop RDF Tools

> Key: JENA-666
> URL: https://issues.apache.org/jira/browse/JENA-666
> Project: Apache Jena
> Issue Type: Task
> Reporter: Rob Vesse
> Assignee: Andy Seaborne
> Priority: Minor
> Labels: hadoop, ip, ip-cl, rdf
> Attachments: Hadoop RDF Tools - External Version.pdf, Hadoop RDF

>
> Hadoop RDF Tools is a set of experimental modules developed internally at my
> employer (Cray) that has been agreed to open source by donating to the Jena
> project in order that the wider community can further their development.
> The donated code base comprises of 4 modules:
> - Hadoop RDF Common - Set of {{Writable}} implementations for representing
> primitive RDF types i.e. nodes, triples, quads
> - Hadoop RDF IO - Set of {{InputFormat}}, {{RecordReader}}, {{OutputFormat}}
> and {{RecordWriter}} implementations for consuming/producing RDF from Hadoop
> programs.
> - Hadoop RDF Map/Reduce - Set of {{Mapper}} and {{Reducer}} implementations
> that provide some common operations that users are likely to want to do with
> RDF data
> - Hadoop RDF Stats - Demo application that uses the other libraries to
> analyse some RDF data and produce various statistics on it
> Since this code was developed outside of the Apache process it is required to
> go through the IP Clearance procedure which is managed by the Incubator -
> https://incubator.apache.org/ip-clearance/index.html
> This issue will act as a tracking point for tasks related to carrying out the
> IP Clearance process.
