Subject [PROPOSAL] Solr
Date Tue, 03 Jan 2006 15:19:16 GMT
Hello Incubator PMC folks,

I would like to propose a new Apache project named Solr.
The project is being proposed as a sub-project of Lucene, and the
Lucene PMC has agreed to be the sponsor.


'''Proposal for new project Solr '''

Yonik Seeley -- yonik at apache dot org

'''(0) rationale'''

Solr is a search server based on Apache Lucene and focused on
full-text search, relevancy, and performance.

Some of the server features include:
   * Query and update interfaces over HTTP and XML.
   * Replication based on index snapshots and rsync.
   * A schema allowing declarative specification of fields and their
types, including specification of text analysis filter chains.
   * External configuration for Lucene parameters, stopword lists, and
synonym lists.
   * A web based admin interface with statistics and debugging.
   * An extensive caching framework for filters, queries, documents,
and user caches.
   * Plugins for customizing query handling, caching and many other
server aspects.

Solr is currently an internal CNET project, and is used to power
search and faceted browsing in a number of CNET sites.

'''(0.1) criteria'''

''Meritocracy: ''

Solr's developers are comfortable operating as a meritocracy.

''Community: ''

Establishing an active open source community will be the top priority.

''Core Developers:''

Solr starts with three committers.


Solr currently uses the following Apache projects: Ant, Lucene.

'''(0.2) warning signs'''

''Orphaned products: ''

Solr is not an orphan, use within CNET is growing rapidly.

''Inexperience with open source:''

Solr's committers are experienced with open source and have made
contributions to other open source projects.

''Homogenous developers:''

Solr's initial committers are all CNET employees since it's currently
an internal project.

''Reliance on salaried developers:''

Some committers are currently paid to make contributions to Solr.

''No ties to other Apache products:''

Solr has strong ties to Lucene.

''A fascination with the Apache brand:''

The committers respect the Apache brand and feel that Apache is the
right place to generate a strong open source community.

'''(1) scope of the subprojects'''

The scope of the project is to provide a stand-alone full-text search server.
The proposal is that this project become a sub-project of Apache Lucene.
