Subject [VOTE] Accept Openmeetings to Apache Incubator
Date Tue, 08 Nov 2011 06:53:41 GMT
Opemeetings proposal has been discussed a few times here before. The group of developers behind
it worked hard (and succeeded) to address all potential obstacles to the Incubator acceptance
and to the following incubation. They even went an extra mile and collected all ICLAs in adbvance.

So now I am starting the vote to accept Openmeetings to Apache Incubator.

The proposal is also available at:

Please cast your votes:

[ ] +1 Accept Openmeetings for incubation
[ ] +0 Don't care
[ ] -1 Reject for the following reason:

The vote is open for 72 hours.

== OpenMeetings Project Proposal ==

== Abstract ==
Openmeetings is a web conferencing solution.

== Proposal ==
Openmeetings provides video conferencing, instant messaging, white board, collaborative document
editing and other groupware tools using API functions of the Red5 Streaming Server for Remoting
and Streaming.

== Background ==
Openmeetings was developed since 2007 by Sebastian Wagner and willing developers. The project
ships a release approximately once per quarter. It was developed using LGPL license, and developers
are currently thinking of re-licensing it under Apache License 2.0.

The project started as module by Sebastian Wagner for an ELearning platform (Dokeos) and was
then split into a separated project. That is the reason why there is a strong relation to
educational institutions that are using OpenMeetings and there are integrations for platforms
like Moodle, ATutor, Sakai, STudIP or ILias available (
The relation to educational institutions also subsequently lead to some projects funded by
the EU where OpenMeetings was involved, for example by the Swedish/Finnish Centre of Open-Source
!OpenKarken (Case-Study about the EU project at

The integration and internationalization of the project was a primary focus right from the
start of the project. Since Version 0.5 there is a Language-Editor (
to edit labels, export and import them as XML and you can use those XML files for future installations
(or contribute it to the community). There are currently around 30 languages available.  Since
version 0.5.1 there is also a SOAP API to integrate !OpenMeetings. We constantly improve this
SOAP/REST API ( with new functionality
with a strong focus on security and usability. The auth-mechnism is quite similar to OAuth,
you create some token and then assign rights to the token. (Documentation for Single Sign

The project name "!OpenMeetings" and logos are inspired by Ludovic Gasc who has been the project
manager at Dokeos at the time Sebastian split !OpenMeetings as separated project.

Red5 Server provides an "Edge-Orion-Clustering" (
 We hope to extend this clustering solution with support for rtmpt and  rtmps and integrate
that into our application as native clustering  option.

== Rationale ==
Last year most major vendors started commercial web conferencing solutions. This is an important
part of software ecosystem, and there is an urge to consolidate open source development efforts
in this direction.

According to several studies demand for synchronous Communication, in opposite to asynchronous
Communication like wiki's or email, will raise the upcoming years. For example Gartner promises
that 2011 the market will grow 20% according to their "Magic Quadrant" report 2010 (

Openmeetings is a unique solution in terms of patent purity and potentially can grow into
solution built on top of the fully open source stack. That is why it is a good candidate for
consolidating web conferencing community efforts.

== Initial Goals ==
Each of project committers has their own set of goals, but we all share the following.

 * Move to Apache.
 * Become popular.

To become popular we plan to do the following.

 * Improve ecosystem around the project.
 * Improve release process.
 * Improve project testing and stability.
 * Apply modular architecture/SOA for better integration with other projects.

== Current Status ==
We have agreed on applying for the Apache Foundation and preparing our proposal for the vote.

Technical status of the project is: Current stable tree is 1.8.x, Trunk is 1.9.

=== Meritocracy ===
Developers community is successfully driven by consensus now. If there are more developers
on board, consensus may turn into meritocracy.

=== Community ===
The developer community is active. The mailing list is active with dozens of messages every
day, mostly user support topics.

Currently the User Mailing list has over 1000 members, the dev-list has around 250.

=== Core Developers ===
Sebastian has started the application 07/2006. Current development team counts 21 programmers
from Germany, Russia, China, India and South America.

=== Alignment ===
The project provides a safe ground for Apache for entering a complex field of video streaming.
It avoids complex patenting issues by using proprietary Adobe Flash. From the other side it
may grow into independent solution because it uses OpenLaszlo RIA framework rather than a
particular proprietary vendor language, and after framework evolves can use other frontend
representations such as javascript.

== Known Risks ==
=== Orphaned Projects ===
Openmeetings project has developed a sufficient functionality to be a popular solution for
a small businesses. The number of site visits of the googlecode project website increased
to 50.000 in October 2011 which is a good sign of people interest. The overall statistics
for the last 4 years shows around 4 mio pageviews (google-analytics graphic:
 We believe that visitors convert to users, and users convert to developers in some standard

=== Inexperience With Open Source ===
Two committers have GSoC experience. One committer is an Apache committer. The project exists
since 07/2008 already as an open source project hosted at !GoogleCode

=== Reliance On Salaried Developers ===
Some contributors get paid from Openmeetings-based consultancy.

=== Relationships with Other Apache Products ===
Web application part of Openmeetings runs under Apache Tomcat. It uses Apache Commons and
Apache Velocity. Red5 server uses a lot of Apache components, including Apache Mina. !OpenMeetings
itself uses Apache Axis2 for the SOAP / REST API. !OpenMeetings was reworked to use Apache
OpenJPA instead of Hibernate. Since revision 4000 (version 1.8) all dependencies to Hibernate
have been removed from the source.

=== An Excessive Fascination with the Apache Brand ===
The Apache Foundation is the home of vendor neutral and industry standard software. By joining
the Foundation we will apply Apache's Release and Licensing Standards to our product. Doing
that we will improve our release processes, quality standards and it should give a planning
reliability to our end users. But our main motivation is that our project is about collaboration,
communication and enabling people to easily interact with each other. We think that the "Apache
Way" of community driven software development with flat hierarchy and transparency in decision
and design will reflect best those core activities of our software.

Well, or course we want our project to be alive, and useful. Several contributors have former
experience with Apache Harmony project (which previously has been known as SourceForge ORP
project). Apache brand is really helpful compared to SourceForge brand for community building
and getting support from commercial companies. From the other side org.apache.harmony story
shows that the brand cannot help when there no community remain. Hence we try to keep people
interested, and the product developed at the first place, thus supporting Apache brand fame
with good facts.

== Initial Source ==

=== External Dependencies ===
Adobe Flash (by means of !OpenLaszlo) and open source projects compliant with current Apache
policy. The UI code is compiled by using !OpenLaszlo, not by using Adobe products. !OpenLaszlo
is licenced under the CPL. !OpenLaszlo's concept is that you write the code in a XML based
approach, it is possible to compile the output to Flash or DHTML/HTML5. So on the long run
it might be possible to replace the Flash UI with a DHTML one. But as there is little multimedia
support in HTML5 especially for Webcam and Microphone access it is not possible yet to prevent
using Flash in general. The needed Real-Time Communication could be done using Ajax and HTTP-Push
mechanisms like Comet instead of AMF which is currently used.

For Flash Streaming Red5 is used ( ). Red5 is currently a LGPL
licensed Software based on Apache Tomcat / Apache MINA and Spring. Red5 will change to APL
very soon, they already internally discussed that some time ago and voted on it:!searchin/red5developers/apache/red5developers/QkwBygXUGM0/KK4uICz0wEsJ

Dependcies to Red5 API as graphs: Java Web-Start application (Screen-Sharing and Recording) Java Web-Application
( ).

=== Cryptography ===
OpenMeetings can be deployed using HTTPS and RTMPS (Flash Streaming and Remoting over SSL):

Continuous integration and Nightly Builds may eventually require hardware

We are currently hosted on googlecode. There was an option in googlecode available to transfer
a googlecode project to Apache. We would like to ask the hosting staff at Googlecode if they
could maybe give us advice how we can easily get a copy of our project to import it into the
new project space at Apache.
