This package was created with Cookiecutter and the audreyr/cookiecutter-pypackage project template.


0.0.1 (2016-02-17)

First alpha release on PyPI.

Additional features added with no backwards-incompatible interface changes. COALA IP models are backwards-incompatible to previous versions due to upgrades related to spec changes.

Some highlights:

  • Queryability of an Entity’s ownership history and current owner
  • Entities can be given a custom @id
  • Additional sanity checks employed when deriving Rights, to ensure that a correct source Right and current holder are given
  • Update COALA IP models to latest spec
  • Added usage documentation

0.0.1.dev3 (2016-12-06)

Lots of changes and revisions from 0.0.1.dev2. Totally incompatible from before.

Some highlights:

  • Implemented Rights derivation (from existing Rights and Copyrights)
  • Implemented Rights transfers
  • Entities are now best-effort immutable
  • Support for loading Entities from a connected persistence layer

0.0.1.dev2 (2016-08-31)

  • Fix packaging on PyPI

0.0.1.dev1 (2016-08-31)

  • Development (pre-alpha) release on PyPI.
