Proposal for Tobago, a MyFaces subproject

18th August 2005, the Tobago Team (contributions by: Udo Schnurpfeil, Volker Weber, Philippe Hennes, Arvid Hülsebus, Bernd Bohmann, Detlef Bartetzko)

(0) rationale:

The goal of Tobago is to provide the community with a well designed set of user interface components based on JSF and run on MyFaces.

Tobago is more than just a tag library. The following statements characterize Tobago and makes it different from other frameworks:

The development of Tobago started in 2002.

(0.1) criteria


The Tobago project will be meritocratic. The project will therefore follow the guidelines of the Apache Foundation.

We use defined roles and responsibilities like contributors and committers.

We believe in teamwork and in the consens brought by discussions that are done on a mailing list. Votings will establish the final 'will' of the community.


We believe that Tobago will attract a stable community sufficient in size. All MyFaces users/developers are potential Tobago users/developers. Tobago will make MyFaces even more attractive.

Core Developers:

Tobago was mainly developed by six employees of Atanion while working (if applicable) and in spare time. However, at the moment two of them could be counted as real experts or core developers and the others have a good knowledge of the project.

All developers will file the Contribution License Agreement. Atanion GmbH will file the Corporate Contribution License Agreement.

Two PMC members from the MyFaces project also want to become Tobago committers:


* Tobago is a framework built on top of JSF and therefore works well with MyFaces. * The project makes use of several Apache libraries like Commons, Taglibs and Ant.

(0.2) Warning signs

Orphaned products:

All active developers would like to become Tobago Committers or PMC members and plan to remain active in the project.

Inexperience with open source:

The current Tobago developers have experience with open source projects. However in the past this was restricted by using open source projects and participating on there mailing lists. No active development was done.

Martin Marinschek and Matthias Wessendorf do have a lot of experience with open source.

Homogenous developers:

From scratch the project will start with six developers of one company and two additional developers from other companies. We hope to attract more individual developers soon.

Reliance on salaried developers:

Tobago was developed in working and spare time and does not rely on salaried developers. However Atanion will support the project in the future by dedicating 'work time' to Tobago.

No ties to other Apache products:

Tobago makes excessive use of serveral components of the Jakarta Commons. It is developed on the Tomcat JSP/Servlet container. (However it runs also on other containers.) Tobago is the ideal addition for MyFaces.

A fascination with the Apache brand:

We respect and admire the work done by the Apache Foundation. Various open source projects of the foundation have saved us an almost unlimited amount of development time or money in case of not using commercial products. We want to give something back to the community and become part of it.

(1) scope of the subprojects

As mentioned above Tobago is the ideal addition for MyFaces. Therefore we prefer to become a subproject of MyFaces.

(2) identify the initial source from which the subproject is to be populated

The source code can be found under:

The source code is provided under the Apache License, version 2.0.

A precompiled WAR for the demo can be found at:

(3) identify the ASF resources to be created

(3.1) mailing list(s)

At the moment the existing mailing lists of the MyFaces project should be sufficient to discuss and announce Tobago topics. If not, we need the following lists:

(3.2) Subversion or CVS repositories

A subversion repository with one module 'incubator-tobago'.

(3.3) Issue Tracking

At the moment the MyFaces JIRA module could be used.

(4) identify the initial set of committers

(4.1) Already ASF committers

(4.2) New committers

(5) identify apache sponsoring individual
