Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Lucy Wiki" for chan=
ge notification.

The "LucyIncubatorProposal" page has been changed by MarvinHumphrey.
The comment on this change is: Add Proposal, tweak Abstract, add obligatory=
 "loose C" reference..

ev2=3D25

--------------------------------------------------

  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 p=
roject by assimilating the KinoSearch code base, and enter the Incubator on=
 a top-level-project track.
  =

  =3D=3D Abstract =3D=3D
- Lucy will be a loose port of the Lucene search engine library, written in=
 C and targeted at dynamic languages.
+ Lucy will be a high-performance search engine library written in C and ta=
rgeted at dynamic language users.
  =

  =3D=3D Proposal =3D=3D
- A lengthier description of the proposal. Should be reasonably declarative=
. More discursive material should be included in the rationale (or other la=
ter sections). Example (XAP): XAP is to provide an XML-based declarative fr=
amework for building, deploying and maintaining rich, interactive, Ajax-pow=
ered web applications. A basic principal of XAP is to leverage existing Aja=
x ...
+ 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 vi=
a dynamic language bindings.  To that end, it will present highly idiomatic=
, carefully tailored APIs for each of its "host" binding languages, includi=
ng full support for subclasses written entirely in the "host" language.

  =3D=3D Background =3D=3D
- Lucy began as an ambitious, from-scratch Lucene sub-project, with initial=
 committers David Balmain (author of Ferret, a Ruby/C port of Lucene), Doug=
 Cutting, and Marvin Humphrey (founder of KinoSearch, a Perl/C port).  Duri=
ng an initial burst of activity, the overall architecture for Lucy was sket=
ched out by Dave and Marvin.  Unfortunately, Dave became unavailable soon a=
fter, and without a working code base to release or any users, it proved di=
fficult to replace him.  Still, Marvin carried on their work throughout a p=
eriod of seeming dormancy.

  In the last year, the work has come to fruition: major technical mileston=
es have been achieved and Lucy's underpinnings have been completed.  Additi=
onally, other developers from the KinoSearch community have taken an intere=
st in Lucy and have begun to ramp up their contributions.  The next steps f=
or Lucy were articulated by the Lucene PMC in a recent review: make release=
s, acquire users, grow community.
