Subject [DISCUSS] CouchDB incubator project
Date Thu, 31 Jan 2008 15:40:17 GMT
The original source for this proposal can be found at

and a current snapshot is attached below.  Once we have established that 
there is interest, my plan is to move this content over to as a [PROPOSAL].

I've been watching CouchDB since September, and believe that it would 
fit well in the ASF.  My preference is that it exits as a top level 
project, mainly due to my experience with umbrella PMCs, but I would 
otherwise not be adverse to it joining the DB project.  We certainly do 
not need to decide this now.

Project Name: CouchDB

The goal is to create either an Apache top level project, or a db 
subproject, around the existing CouchDB open source project.

Key Features:
* a REST API using JSON for data transport,
* a JavaScript view engine based on Mozilla Spidermonkey,
* a GNU Autotools build system supporting most POSIX systems
* a built-in administration interface
* experimental fulltext search with Lucene

The goals of the project are aligned with the goals of the ASF, namely 
there is interest in (continuing to) foster a collaborative, consensus 
based development process, using an open and pragmatic software license, 
and a desire to create high quality software that leads the way in its 

===Initial goals===
* Features for next release
**  Incremental reduce support, for full map/reduce support.
** Document validation model (validate live and replicated changes)
** Documentation, Documentation, Documentation
** Fulltext Search
* Priority feature work
** Live compaction
** Extensible security model
** LDAP authentication
** More query capabilities exposed to HTTP, e.g. multi-key view lookups
* Future feature work
** Server storage partioning
** Server failover clustering
* Requested Features
** hierarchical structure in documents

==Current Status==

The project has recently transformed from being primarily a single 
person led (and funded) project to one with a number of diverse 
participants.  Development has been coordinated primarily through a 
mailing list, with some IRC.

The community consists of a set of independent developers, one of which 
recently joined IBM

===Initial Developers===
* William Beh
* Damien Katz
* Jan Lehnardt
* Christopher Lenz
* Dirk Schalge
* Noah Slater

A database server with a strong focus on HTTP and REST principles.

===Known Risks===
* Dependency on Erlang
** Including some modifications to the HTTP server stack.  The plan is 
to convert over to [ MochiWeb] (MIT 
* Dependency on Mozilla SpiderMonkey
** Including small modifications, to be sent back to Mozilla

===Orphaned Products===
* This is a new effort, and is far from being orphaned.

===Inexperience with Open Source===
All participants are active users and contributors to open source. One 
of them (Christopher Lenz) has experience as committer on other Apache 

===Homogenous Developers===
The exiting committers are spread over a number of countries and employers.

===Reliance on Salaried Developers===
Only one developer is being paid to work on CouchDB.  Read 
[ his views] on the 
relationship he has with his employer.

===Relationships with Other Apache Products===
Experimental usage of Lucene

===An excessive fascination with the Apache brand===
This product started out independent of Apache and under a GPL license. 
  After discussions with a number of people within IBM, Damien Katz 
agreed to pursue both incubation at the ASF, and employment at IBM


===Initial Source===
Resides on [ Google Code].  The code 
has been recently relicensed from GPL to the Apache License, Version 
2.0, in anticipation of this submission.

===Source and Intellectual Property Submission Plan===
The bulk of the core code was written by Damien Katz.  Major 
contributions include: a GNU Autotools build system supporting most 
POSIX systems contributed by Noah Slater,  a built-in administration 
interface provided by Christopher Lenz, and experimental fulltext search 
with Lucene by Jan Lehnardt.  ICLAs either have been, or are in the 
process of being, submitted for all code involved in this submission.

ICLA's are already on file for:
* Jan Lehnardt
* Christopher Lenz
ICLA's in progress:
* William Beh
* Damien Katz
* Dirk Schalge
* Noah Slater

There are a few (as in single digit) number of files that we are 
continuing to sort through the licenses.  These include Public Domain, X 
Consortium, and MITish licenses.

===External Dependencies===
* [ ICU] (MIT)
* [ Erlang] (Erlang Public License)
* [ SpiderMonkey] (Mozilla Public 

Not applicable

===Required Resources===
* Mailing lists:
** couchdb-pmc for private PMC discussions (with moderated subscriptions)
** couchdb-dev
** couchdb-commits
** couchdb-user
* Subversion Directory:
* Issue Tracking:
** JIRA couchdb

===Initial Committers===
* William Beh
* Damien Katz
* Jan Lehnardt
* Christopher Lenz
