          <section name="Purpose">
              <p>
                  This document describes the list of tasks on
                  the plates of the Lucene development team. Tasks are assigned into two
                  categories: core or non-core.
              </p>
          </section>
          <section name="About Core vs. Non-Core Development">
              <p>
                  Currently the Lucene development team is working on
                  categorizing change requests into <b>core</b> and <b>non-core</b>
                  changes.
              </p>
              <p>
                  Core changes would entail a change to the search engine
                  core itself. From Doug Cutting:
                  <blockquote><i>
                          "Examples include: file locking to make things
                          multi-process safe; adding an API for boosting individual documents
and fields
                          values; making the scoring API extensible and public; etc."
                      </i></blockquote>
              </p>
              <p>
                  Non-core changes would not affect the search engine
                  itself, but would consist instead of projects or components that would
                  make useful
                  additions to the core framework. Again, from Doug
                  Cutting:
                  <blockquote><i>
                          "[Examples] include: support for more languages; query
                          parsers; database storage; crawlers, etc.  Whether these belong
in the
                          base distribution is a matter of debate (sometimes hot).  My rule
of
                          thumb for including them is their generality: if they are likely
to be
                          useful to a large proportion of Lucene users then they should probably
go
                          in the base distribution.  Language support in particular is tricky.
                          Perhaps we should migrate to a model where the base distribution
                          includes no analyzers, and supply separate language packages."
                      </i></blockquote>
              </p>
              <p>
                  Change requests will be categorically defined by the
                  development team (committers) as core or non-core, and a committer will
                  be assigned responsibility for
                  coordinating development of the change request. All
                  change requests should be submitted to one of the Lucene mailing lists,
or
                  through
                  the <a href="http://issues.apache.org/bugzilla/">Apache
                      Bugzilla</a> database.
