Subject Re: [VOTE] Move Lucy to the Incubator
Date Sun, 18 Jul 2010 19:07:55 GMT

+1,  binding (as of this morning if i did my math correctly)


: I would like to call a vote for accepting "Apache Lucy" for incubation in the
: Apache Incubator. The full proposal is available below.  We ask the Incubator
: PMC to sponsor it, with myself (hossman) as Champion, and mattmann, upayavira,
: mikemccand, and hossman volunteering to be Mentors.
: 
: Please cast your vote:
: 
: [ ] +1, bring Lucy into Incubator
: [ ] +0, I don't care either way,
: [ ] -1, do not bring Lucy into Incubator, because...
: 
: This vote will be open for 72 hours and only votes from the Incubator PMC are
: binding.

: ------------------------------------
: PREFACE
:     Lucy is a sub-project which is being spun off from the Lucene TLP but is
:     not yet ready for graduation.  We propose to address certain needs of the
:     project by transitioning to an Incubator Podling, and assimilating the
:     KinoSearch codebase.
: 
: ABSTRACT
:     Lucy will be a loose port of the Lucene search engine library, written in
:     C and targeted at dynamic language users.
: 
: PROPOSAL
:     Lucy has two aims.  First, it will be a high-performance C search engine
:     library.  Second, it will maximize its usability and power when accessed
:     via dynamic language bindings.  To that end, it will present highly
:     idiomatic, carefully tailored APIs for each of its "host" binding
:     languages, including support for subclasses written entirely in the
:     "host" language.
: 
: BACKGROUND
:     Lucy, a "loose C" port of Java Lucene, began as an ambitious,
:     from-scratch Lucene sub-project, with David Balmain (author of Ferret, a
:     Ruby/C port of Lucene), Doug Cutting, and Marvin Humphrey (founder of
:     KinoSearch, a Perl/C port) as committers.  During an initial burst of
:     activity, the overall architecture for Lucy was sketched out by Dave and
:     Marvin.  Unfortunately, Dave became unavailable soon after, and without a
:     working codebase to release or any users, it proved difficult to replace
:     him.  Still, Marvin carried on their work throughout a period of
:     seemingly low activity.
: 
:     In the last year, that work has come to fruition: major technical
:     milestones have been achieved and Lucy's underpinnings have been
:     completed.  Additionally, other developers from the KinoSearch community
:     have taken an interest in Lucy and have begun to ramp up their
:     contributions.  The next steps for Lucy were articulated by the Lucene
:     PMC in a recent review: make releases, acquire users, grow community.
: 
:     To implement the Lucene PMC's recommendations and get to a release as
:     quickly as possible, the Lucy community proposes to assimilate the
:     KinoSearch codebase, which has been retrofitted to use Lucy's core.  Lucy
:     still lacks a number of important indexing and search classes; we wish to
:     flesh these out via IP clearance work rather than software development.
: 
:     Because Lucene is working to move away from being an "umbrella project",
:     a long term goal of the Lucy project is to graduate to an ASF TLP.  With
:     that in mind, it seems more appropriate for the KinoSearch software grant
:     to take place within the context of the Incubator, and that a Lucy
:     podling and PPMC be established which will ultimately take responsibility
:     for the codebase.
: 
: RATIONALE
:     There is great hunger for a search engine library in the mode of Lucene
:     which is accessible from various dynamic languages, and for one
:     accessible from pure C.  Individuals naturally wish to code in their
:     language of choice.  Organizations which do not have significant Java
:     expertise may not want to support Java strictly for the sake of running a
:     Lucene installation.  Developers may want to take advantage of C's
:     interoperability and fine-grained control.  Lucy will meet all these
:     demands.
: 
:     Apache is a natural home for our project given the way it has always
:     operated: user-driven innovation, security as a requirement, lively and
:     amiable mailing list discussions, strength through diversity, and so on.
:     We feel comfortable here, and we believe that we will become exemplary
:     Apache citizens.
: 
: INITIAL GOALS
:     * Make a 1.0 stable release as quickly as possible.
:     * Concentrate on community expansion.
:     * Expose a public C API.
: 
: CURRENT STATUS
:   Meritocracy
:     Our initial committer list includes two individuals (Peter Karman and
:     Nathan Kurz) who started off as KinoSearch users, demonstrated merit
:     through constructive forum participation, adept negotiation, consensus
:     building, and submission of high-quality contributions, and were invited
:     to become committers.  Peter now rolls most releases.
: 
:     We look forward to continuing to operate as a meritocracy under the
:     established traditions and rules of the ASF.
: 
:   Community
:     Lucy's most active participants of late have been drawn from the
:     KinoSearch and Lucene communities.  Having been focused on features and
:     technical goals for a long time, we are considerably overdue for a stable
:     release, and anticipate rapid growth in its wake.
: 
:   Core Developers
:     * Marvin Humphrey is the project founder of KinoSearch, and co-founded
:       the existing Lucy sub-project.  He is presently employed by Eventful,
:       Inc.
:     * Peter Karman has contributed to several open source projects since
:       2001, including being a committer at http://swish-e.org/ (a search
:       engine), http://code.google.com/p/rose/ (an ORM) and
:       http://catalyst.perl.org/ (web framework).  He is employed by American
:       Public Media.
:     * Nathan Kurz is excited by the intersection of search and
:       recommendations, and has been a KinoSearch committer since 2007.  As
:       the owner of Scream Sorbet (http://screamsorbet.com), he divides his
:       time between code and fruit.
: 
:   Alignment
:     One Apache value which is particularly cherished by the Lucy community is
:     codebase transparency.  We have developed institutions which enable us to
:     measure and maximize usability (see
:     http://wiki.apache.org/lucy/BrainLog), and we feel strongly that the
:     bindings for Lucy must present APIs and documentation which are idiomatic
:     to the host language culture so that end users can consume our work as
:     easily as possible.
: 
:     The controlled competition of meritocratic community development is also
:     very important to us.  There has been substantial cross-pollination of
:     ideas between Lucene and Lucy, yielding considerable benefits for both
:     projects.  The Lucy developers envision that our host-language
:     sub-communities will approach using and extending the library in distinct
:     ways; we hope to harness the creative tension between them to drive
:     innovation, building productive relationships akin to the one that Lucene
:     and Lucy have today.
: 
:     A third priority of ours is to be bound by existing Apache institutions,
:     for the protection of all our stakeholders.
: 
: KNOWN RISKS
:   Orphaned products
:     All core developers have been associated with the project for several
:     years across multiple jobs.  However, at this time, the project would
:     probably not survive the departure of Marvin Humphrey, so there is a risk
:     of being orphaned.  Marvin has no plans to leave, but we have been
:     actively working to disperse his knowledge of the code base and
:     administrative responsibilities in order to make him dispensable.  Having
:     staggered badly after Dave Balmain's departure, we are keenly aware of
:     this vulnerability and highly motivated to eliminate it.
: 
:   Inexperience with Open Source
:     The core developers all have significant experience with open source
:     development, and include one present Apache committer.  We recognize that
:     we lack PMC experience and seek to address that deficiency by using the
:     Incubator environment to educate ourselves and prepare for responsible
:     self-governance.
: 
:   Homogenous Developers
:     Our community is geographically dispersed, with members in San Diego,
:     Oakland, and Minneapolis.  We all work for different organizations.
: 
:   Reliance on Salaried Developers
:     Marvin Humphrey has a great job at Eventful working primarily on this
:     project and supporting applications that use it.  Nevertheless, he is
:     extremely dedicated to Lucy and is determined to see it through to the
:     point where it becomes self-sustaining, regardless of work circumstances.
: 
:   Relationships with Other Apache Products
:     Lucy's relationship with Lucene of cordial "coopetition" has produced
:     benefits for Lucene users in terms of indexing speed, near-real-time
:     search support, and more.  We expect this dynamic to continue delivering
:     improvements for all parties involved.
: 
:   An Excessive Fascination with the Apache Brand
:     Our desire to maintain Lucy's affiliation with Apache has less to do with
:     the brand and more to do with our conviction that developing the project
:     The Apache Way under Apache institutions is in Lucy's best interests.
:     However, we have to acknowledge that during its time as a Lucene
:     subproject, Lucy has not always fulfilled certain key requirements for an
:     Apache project.  In particular, it has failed to "release early, release
:     often", and it has made minimal progress in expanding its community.
: 
:     We attribute some of our difficulties to the what may have been excess
:     ambition in the original Lucy plan, given the scope of the project and
:     the size of the initial committer list:
: 
:         http://www.apache.org/foundation/how-it-works.html#incubator
: 
:         The basic requirements for incubation are:
: 
:           * a working codebase -- over the years and after several failures,
:             the foundation came to understand that without an initial working
:             codebase, it is generally hard to bootstrap a community.
: 
:     By rebooting the project with a working codebase, we expect to avoid the
:     trap that ensnared Lucy's first incarnation: we will release early,
:     release often, accumulate users, nurture contributors, and grow our
:     community.

: 
: INITIAL SOURCE
:     The initial source will be a snapshot from the KinoSearch subversion
:     repository.
: 
: SOURCE AND INTELLECTUAL PROPERTY SUBMISSION PLAN
:     KinoSearch is currently under a GPL/Artistic license.  There are five
:     individuals who have made multiple significant contributions to the
:     codebase and whose participation is either essential or would be very
:     helpful: Marvin Humphrey, Peter Karman, Nathan Kurz, Chris Nandor, and
:     Father Chrysostomos.  All have been contacted and are amenable to
:     re-licensing their work and contributing it to Apache.  We will contact
:     as many other contributors as possible; if there are any that we cannot
:     obtain permission from, we will refactor to expunge their work.
: 
: EXTERNAL DEPENDENCIES
:     The Perl bindings for KinoSearch currently depend on a few CPAN modules
:     which do not have Apache-compatible licenses.  It will be possible to
:     eliminate all such dependencies if necessary.
: 
: REQUIRED RESOURCES
:   Mailing lists
:     * lucy-dev
:     * lucy-private (with moderated subscriptions)
:     * lucy-commits
:     * lucy-users
: 
:     Lucy already has lucy-dev, lucy-users, and lucy-commits mailing lists
:     under lucene.apache.org.  Perhaps these could be deactivated and the
:     memberships migrated to the appropriate lists under incubator.apache.org,
:     leaving the lucene.apache.org archives as read-only.
: 
:   Subversion Directory
:     Lucy already has a Subversion directory at
:     http://svn.apache.org/repos/asf/lucene/lucy. In keeping with naming
:     conventions, it could be moved to
:     http://svn.apache.org/repos/asf/incubator/lucy.
: 
:   Issue Tracking
:     Lucy already has a JIRA tracker: Lucy (LUCY)
: 
:   Other Resources
:     Lucy already has a MoinMoin wiki at wiki.apache.org/lucy.  It would be
:     convenient to keep it, especially since its current location is also
:     where it would end up upon TLP graduation, but we will defer to the
:     wishes of the Incubator PMC if standard Incubator wiki placement is
:     recommended.

: 
:   Sponsoring Entity
:     Lucy is currently sponsored by Lucene as a sub-project. This proposal
:     advocates changing Lucy's relationship with Apache from developing all
:     new code as a Lucene sub-project, to instead assimilating existing code
:     (KinoSearch) under the sponsorship of the Incubator.
