Subject [PROPOSAL] Apache Steams Project
Date Tue, 06 Nov 2012 17:06:46 GMT
I would like to propose a new Activity Streams server project to the
Incubator.  The proposal is on the wiki at the following location:

Streams is a collaborative effort from multiple organizations and
individuals working with and around the Activity Streams specification

We are looking forward to your feedback and suggestions.

-Matt Franklin


Apache Streams Proposal
== Abstract ==

Apache Streams will be a lightweight server for ActivityStreams. The role
of Apache Streams is to provide a central point of aggregation, filtering
and querying for Activities that have been submitted by disparate systems.
 Apache Streams also intends to include a mechanism for intelligent
filtering and recommendation to reduce the noise to end users.

== Proposal ==

Apache Streams will bring together individuals who are or are looking to
increase and centralize the production, consumption and federation of
ActivityStreams throughout enterprise organizations and the Internet as a
whole.  The target features include:

 * Publication of Activities from multiple systems via HTTP
 * Aggregation and syndication of streams
 * Support for security trimming of streams by social graph
 * Noise reduction and intelligent filtering
 * Federation of streams across disparate systems
 * Provide libraries for easy integration in source systems

== Background ==

The ActivityStreams specification standardizes a generic format for
describing event-based data.  Many social web companies have adopted the
format and it has been included in the OpenSocial specification as the
preferred method for delivery of activity data.  During discussions of
ActivityStreams at OpenSocial events earlier in the year, it became clear
that multiple organizations are facing similar issues as to the
publication and filtering of their activities and would benefit from a
commonly-developed, open-source ActivityStreams server.

== Rationale ==

In deployment, activities are generated from multiple sources.  This is
particularly true within the enterprise where disparate systems create and
manage activities in stove pipes.  What is needed is a central point for
consumption, aggregation and exposure of activities generated within these

== Initial Goals ==

The initial goal of the project is to survey donated code and develop a
common, high-level architecture for an initial release.  The project will
then work toward that release in a new code base, pulling in pieces of
donated code as necessary.

== Current Status ==

The MITRE Corporation will donate its prototype code to the project.
Aside from this, the project is new and will need bootstrap time to
develop an initial architecture and roadmap.

==== Meritocracy ====

As a new project with many team members who are seasoned Apache veterans,
Apache Streams is prepared to build the project under the Apache Way.
==== Community ====

The Apache Streams community combines multiple individuals from different
organizations, many of which have collaborated before in an open
environment.  Apache Streams is committed to expanding this community and
adhering to Apache principles of openness and collaboration.

== Known Risks ==

An exercise in self-knowledge. Risks don't mean that a project is
unacceptable. If they are recognized and noted then they can be addressed
during incubation.

==== Inexperience with Open Source ====

Most of the initial committers have worked in open source and many are
familiar with the ASF and the Apache Way; but, not all.  Additionally,
many of the committers have not worked on a software project together and
will need time to familiarize themselves with each other.

==== Speed of Development ====

This project is dependent upon contributions made on company time. For
this approach to succeed, the project must deliver a workable system in a
timeframe acceptable to those companies. The initial parties have the
intention of releasing a first version within 6 months after starting the
Incubator. Failure to do so could prevent the project reaching critical
mass, and could prevent the project from being in a position to attract
new developers.

==== Reliance on Salaried Developers ====

At present, the vast majority of contributors will be doing so as a part
of their day jobs. Therefore, as already alluded to, there is a risk that
the project won't gain enough traction to be of use to their employers.
However, given the centrality of these codebases to the participating
companies, it is clearly in their best interests to transition to an
openly developed alternative.

==== Relationships with Other Apache Products ====

Many of the initial committers will be integrating this software with
Apache Rave & Apache Shindig.  A possibility exists that code is developed
by either or both of the projects to support integration with Apache

==== An Excessive Fascination with the Apache Brand ====

The rationale for the community to propose the project to Apache is that
Apache offers a meritocratic governance style that is free from direct
influence by any single company.  This allows all of the participants in
this proposal to collaborate regardless of which organization pays them.

== Initial Source and Submission Plan ==

The MITRE Corporation has developed a prototype using Apache Shindig,
Apache Rave and the PubSubHubbub Enterprise Engine (PuSH-EE) [1].  The
source for this will be donated to the ASF upon successful execution of
MITREĀ¹s open source technology transfer process.


== Cryptography ==

The only cryptography included by the project will be via library
inclusion.  As it is currently under discussion at legal-discuss as to
whether or not this qualifies for BIS registration, we propose that any
actions to arise regarding cryptographic libraries be deferred until
suitable resolution to the discussion is achieved.
