Subject [Incubator Wiki] Update of "HelenusProposal" by IanHolsman
Date Fri, 14 Nov 2008 11:15:43 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Incubator Wiki" for change notification.

The following page has been changed by IanHolsman:

New page:
= Abstract =
Helenus is a column orientated p2p storage mechanism designed to deal with large amounts of
data. It is a fork of the Cassandra project [[]]

= Proposal =
We propose to move future development of Helenus/Cassandra to the Apache Software Foundation
in order to build a broader user and developer community. We hope to encourage contributions
to and use of Helenus in internet companies. We have forked from the 'Casandra' project as
the core developers were assigned to other projects and have no time to develop cassandra
= Background =
Cassandra was initially open sourced by facebook in July, where it was presented in SIGMOD
2008 a excellent technical presentation on it's capabilities is available here [[]]

= Rationale =
Cassandra/Helenus attracted a great deal of developer attention based on its unique feature-set
and the underlying technology.  We believe that Helenus's vision is unique in the field.
The Helenus project team is interested in joining the Apache Software Foundation for several

 * To help the project attract contributors who will feel more comfortable with the licensing
coming through a respected, well known and established organization such as Apache.

 * To facilitate the growth of a broader community of users. The project currently lacks sufficiently
clear direction, leadership, and process; we believe the project will benefit greatly from
Incubator mentorship.

 * To Foster greater acceptance of this type of infrastructure within organisations
= Current Status =

== Meritocracy ==
One of the aims of moving to the incubator is to build the meritocracy vital to a successful
open source project.

== Community ==
Many members of the team are 'users' of cassandra in various organizations. We have banded
together to try and save this project.

== Core Developers ==
== Alignment ==
Helenus provides another alternative to groups that require access to large scale data storage
from online web applications.

== License ==
The Helenus codebase is Apache 2.0 licensed, and currently hosted at Google Code.

= Known Risks / Avoiding the Warning Signs =

== Orphaned Products ==
Most of the active developers aim to become Apache committers and have a long term interest
in developing and maintaining the code. 

The main reason we are incubating this is because we feel the current project has been orphaned,
and the committers do not want the project to die.

== Inexperience with Open Source ==
Several of the committers have worked on other open source projects, including the Apache
projects hadoop and httpd.
== Homogenous Developers ==
The Helenus project team consists of several individuals who are installing this product in
their respective organisations, and doing research with it. 

The current list of committers includes developers from several different companies and universities
. The committers are geographically distributed across the U.S., Europe, and Australia.
== Reliance on Salaried Developers ==

== Relationships with Other Apache Products ==
No direct relationship

== An Excessive Fascination with the Apache Brand ==
The Helenus team will strive to avoid inadvertent abuse of the Apache brand and will work
with the Incubator to ensure the brand policies are respected. Although the impact of the
Apache brand cannot be ignored, it is more a valuable by-product of joining the Apache Software
Foundation than an aim in itself: our primary motivation is to enable Helenus to benefit from
the Apache Incubator's experience with the community building. This would provide us with
direction and help identify ways to improve our processes. 

== Documentation ==
 * []

== Initial Source ==
the code is currently hosted on a Google-Code Subversion server.
