Cayenne Project Incubation Status

This page tracks the project status, incubator-wise. For more general project status, look on the project website.

The Cayenne project graduated on 2006-12-20


Cayenne is an open source component-oriented persistence framework licensed under the Apache License, providing object-relational mapping (ORM) and remoting services. With a wealth of unique and powerful features, Cayenne can address a wide range of persistence needs. Cayenne seamlessly binds one or more database schemas directly to Java objects, managing atomic commit and rollbacks, SQL generation, joins, sequences, and more. With Cayenne's Remote Object Persistence, those Java objects can even be persisted out to clients via Web Services. Or, with native XML serialization, objects can be even further persisted to non-Java clients - such as an Ajax-capable browser. In addition to this existing functionality, Cayenne is currently building a JPA-compatible persistence provider (JSR-220). In 2001, Cayenne was started as an open source collaborative environment, modeled after ASF. Thus, proposing Cayenne as an ASF project is the logical next step to further expand the community and increase participation.

Incubation status reports

Incubation work items

Project Setup

This is the first phase on incubation, needed to start the project at Apache.

Item assignment is shown by the Apache id. Completed tasks are shown by the completion date (YYYY-MM-dd).

Identify the project to be incubated

date item
Done - 2006-03-13 Make sure that the requested project name does not already exist and check to be sure that the name is not already trademarked for an existing software product.
N/A If request from an existing Apache project to adopt an external package, then ask the Apache project for the SVN module and mail address names.
Done 2006-02-25 If request from outside Apache to enter an existing Apache project, then post a message to that project for them to decide on acceptance.
....-..-.. If request from anywhere to become a stand-alone PMC, then assess the fit with the ASF, and create the lists and modules under the incubator address/module names if accepted.

Interim responsibility

date item
Done 2006-03-13 Identify all the Mentors for the incubation, by asking all that can be Mentors.
Done - 2006-02-28 Subscribe all Mentors on the pmc and general lists.
Done - 2006-03-13 Give all Mentors access to the incubator SVN repository. (to be done by PMC chair)

These action items have to be checked for during the whole incubation process.

These items are not to be signed as done during incubation, as they may change during incubation. They are to be looked into and described in the status reports and completed in the request for incubation signoff.

Collaborative Development

  • Have all of the active long-term volunteers been identified and acknowledged as committers on the project? YES.
  • Are there three or more independent committers? (The legal definition of independent is long and boring, but basically it means that there is no binding relationship between the individuals, such as a shared employer, that is capable of overriding their free will as individuals, directly or indirectly.) YES. All eight committers are independent of each other -- the Cayenne project originally began as an open source project before coming into the Incubator, so the committers have been independent from the beginning.
  • Are project decisions being made in public by the committers? YES.
  • Are the decision-making guidelines published and agreed to by all of the committers?

Licensing awareness

  • Are all licensing, trademark, credit issues being taken care of and acknowleged by all committers? YES.

  • Has the Incubator decided that the project has accomplished all of the above tasks? 2006-12-05
