Subject:  [VOTE] Proposal: new xml-commons subproject for standards-based files
From:     Shane_Curcuru@lotus.com

I propose a new xml.apache.org/xml-commons subproject to fulfill the need
for a central repository for various XML standards-based files and common

COMMITTERS-PLEASE-VOTE! Although I'm not sure of the exact voting procedure
for creating whole new subprojects, I'm hoping to see a bunch of +1's to
start with; feel free to either reply-to or use the handy mini-xml ballot

NON-COMMITTERS-PLEASE-DISCUSS! While votes from non-committers are not
binding your discussion and insights are very valuable!

Proposal: form a new xml.apache.org subproject called xml-commons to
fulfill the below needs.

(0) Rationale:
Many xml.apache.org projects use and ship with sets of similar
externally-defined standards-based code; differences in versioning and
configuration of this code often make developing and using our projects
more difficult.  A common place for all xml.apache.org projects to get DOM,
SAX, JAXP, and other externally-defined code would be a fairly low-cost and
low-maintenance way to alleviate these difficulties.  Having a subproject
and a community focused on cross-xml-subproject issues will also help drive
better cross-project coordination and tooling.

(0.1) Programming Languages: While the coding details of Java/C/Perl/etc
are obviously different, the core concept is the same: a central repository
for all xml.apache.org projects to share common interfaces and utilities.
We should start with xml-commons/java, xml-commons/c, and xml-commons/perl
since these languages are in current use in various xml.apache.org
subprojects today.

(1) Scope of this subproject:

(1.1) Common externally-defined standards:
This includes the packages: org.w3c.dom.**, org.xml.sax.**, and javax.xml.
**  This is designed to essentially be an xml.apache.org-specific holding
place for commonly-used interfaces/headers that are created outside of
Apache.  This subproject should provide guidelines and build scripts to aid
xml.apache.org groups to easily use these common files in a common manner
across all subprojects.  This subproject should provide some basic
versioning abilities so that xml.apache.org projects temporarily using
new/beta/updated/proposed versions of these specs can continue to get their
code from this area.

(1.2) Common xml-oriented utilities:
We should also include additional utilities/common code in this subproject,
like current copies of bsf.jar, stylebook, servlet API classes, etc.  This
could also include code that did originate in an Apache project, that we
wanted to centralize the use of: SystemIDResolver, XML Serializers, etc.

(1.3) General project starting guidelines for future directions/scope:
While the details of guidelines for this work should be finalized by the
community that forms it (along with input from the other xml.apache.org
projects who will be using this code), there are some basics to start with:
- Communicate status regularly with general@xml.apache.org and with other
- Clearly document and checkin 'best practices' for usage of xml-commons
code in other subprojects
- Proactively work with other subprojects to implement and improve our
'best practices'
- Provide upgrade paths and help; deprecate (or equivalent) old API's
before removing, so other subprojects have ample time to upgrade.
- Test and document all non-standards-based code; provide tests/additional
documentation for standards-based code

(1.4) General guidelines for future directions/scope:
Note this is firstly a subproject to make life inside of xml.apache.org
easier, to enable us to more efficiently develop nifty XML projects.  As we
gain experience in developing this subproject, an obvious future direction
for this community will be to work on a potential AXDK (Apache XML
Development Kit) that would be a meta-packaging-project composed out of
several xml projects together.  The AXDK would be a way to make life for
end-users easier: a single package of various Apache XML tools that works
'out of the box'. (AXDK naming credit to kellyc I think?)

(1.5) Interaction with other subprojects
Additional guidelines can be drawn up on general@xml.apache.org for this
subproject, and then documented and checked in.  These should include both
how other xml subprojects should use these resources in their development
cycles, as well as how all xml subprojects should package these resources
when creating public, shipped distributions (to avoid version conflicts,
etc.)  This subproject's community, along with general@xml.apache.org, will
need to draw up guidelines for code within this subproject as well.

(2) Identify the initial source from which the subproject is to be
Standards-based sources would be obtained from the relevant owners/creators
and checked into the project repository. A basic build.xml file and apache
project usage guidelines would need to be created.  Possible legal review
would be needed for licensed files (one solution might be to waive the
Apache license on these files).  For common xml-oriented utilities, the
initial sources can be moved in from other xml.apache.org subprojects (cf.
potential org.apache.xml.utils.SystemIdResolver from xml-xalan).

(3) Identify the xml.apache.org resources to be created

(3.1) mailing list(s)
(ed note: added xml-commons-cvs as well -Shane)

(3.2) CVS repositories

(3.3) Bugzilla
program: Commons
components: External Standards, Common XML Utils

A sub-issue that I'd like people to vote on separately for whichever of the
below option(s) they like best.
(4) Identify the initial set of committers

(4.a) [vote-multiple] kellyc, curcuru, rubys
(4.b) [vote-multiple] one committer from each xml.apache.org subproject
that wants to volunteer, plus at least one PMC member (for projects that
don't get someone volunteered)
(4.c) [vote-multiple] all current xml.apache.org committers



(*) Important cross-reference:
Jakarta is currently working on a similar, yet different, tool/util/common
code area.  While we can steal a lot of their ideas, I think the needs of
xml.apache.org will be different than Jakarta, so we should make our own
community decision on how to do this.  Many thanks to the nice format for a
proposal that I plagarized.  8-)
