framing and @reverse - java implementation proposal

Hello all,

I am using jsonld-java in a project to expose content of a triple store to
a webapp using a legacy JSON object structure.
To achieve that, i use framing, and I need a context with @reverse
properties.

I have implemented two features for which I would like to get feedback from
this mailing list :
 1. the support for @reverse properties in the framing algorithm
implementation
 2. an extension of the compacting algorithm to allow the definition of
multiple reverse statements for the same property, but different target
types

In particular, the second feature involves an extension of the spec that
re-uses the @type property of reverse statements. I would need confirmation
from people with a deeper understanding of the spec that this is a correct
approach.

These features are available in the fork
https://github.com/pduchesne/jsonld-java/tree/FRAMING_REVERSE .
Tests for both features are in
https://github.com/pduchesne/jsonld-java/blob/FRAMING_REVERSE/core/src/test/java/com/github/jsonldjava/core/JsonLdFramingTest.java
.
Inputs, frames and outputs for both tests are in
https://github.com/pduchesne/jsonld-java/tree/FRAMING_REVERSE/core/src/test/resources/custom
(framing-reverse-*.jsonld) .

thank you,
best regards,
