Introduction

Dec 30, 2012

Background

This project grew out of a proposal on this mailing list thread started by Harald Wellmann in January 2012 titled: Pax Tipi: A third-party bundle repository.
A number of discussion participants, including fellows of ServiceMix and Eclipse' EBR concluded that something like Tipi is a worthwhile idea.

Interaction with original projects

Before starting a new Pax Tipi subproject for a given third-party library, you should always contact the original developers and kindly ask them to osgify their artifacts, offering to submit a patch or a pull request.

Only if this has no effect, use Pax Tipi to wrap and redistribute the given artifacts.

On the fly bundling

The pros and cons of pre-packaging vs. on-the-flying bundling have been discussed on the mailing list. For ease of use and to guarantee immutability, pre-packaging is the preferred approach.

Licensing

As a general rule, OPS4J projects are released under the Apache Software License v2.

To avoid license conflicts for repackaged distributions of non-ASL third-party libraries, Pax Tipi adopts the following licensing policy:

  • Each repackaged artifact shall be released under the license of the original project.
  • Any additions of Pax Tipi to the original projects shall be dual licensed under the Apache Software License v2 and the original license.

Classification

TODO: Classify Pax Tipi artifacts regarding explicit OSGi support or known problems under OSGi.

Source Repository & Release Strategy

Outline:

  • One source repository org.ops4j.pax.tipi on GitHub.
  • One subdirectory for each repackaged third-party library version.
  • Pax Tipi is never released as a whole. Each new subdirectory is released separately.

Additional Features

Eclipse Source Bundles

Each released bundle shall have a source JAR attached. For the benefit of Eclipse users, the source JAR shall be an Eclipse source bundle. This requires nothing but a few additional manifest headers.

OBR

TODO: Can Pax Tipi provide an OBR?

P2

TODO: Can Pax Tipi act as a P2 repository/Eclipse Update Site?
