General
======

- Accept/review minutes of previous meeting
- Reschedule meeting to 13:30 UTC for northern winter [agreed]

Random Developer Updates:
- OpenJDK progress? tests do not run in the same order ..
- JDK 7 - TreeSet no longer accepts null and is more strict
- WMS 1.3.0? Jody is all done, works against GeoServer 2.2 and passes Cite
1.3.0 Client
- GeoServer GetCapabilities needs to include exception formats for
GetCapabilities
- Release Schedule? Andrea, Justin, Jody signed up - need more?


XML dependency removal
===================

- app-schema Xalan dependency has been removed on master
- still used for some tests and one community module
- Justin has a noxmldeps branch (Ben has submitted a pull request for this
branch)

Lets go! This sound great...

app-schema refactoring
===================

Niels had the idea to break out common app-schema functionality (complex
feature construction)
Other interested parties: Adam Brown

Interested? Gabriel wfs client? Jody wants it for wps processes

Goal: Same level of "out of box" hand holding for
FeatureCollection<Feature> as we provided for those working with
SimpleFeature setup

Where: gt-data?

Reference point: Andrea had to make layers of builders in order to use this
kind of setup for CSW (ebRIM record, CSW record). Used Adam's Builder, and
then builders on top of that domains specific.

Notes:
- app schema resolver is indpendent of appschema

Ideas?
- AA: in memory schema = FeatureType of nested Attributes / FeatureType
etc...
- Nested
- Cycles (refer to types that have not been defined yet..)

Oppertunity:
- fast / easy / complex? go for xml blobs (sigh)
- database in normalized form, crawls foreign keys


featurecollection cleanup
===================

GeoTools:
- http://docs.codehaus.org/display/GEOTOOLS/FeatureCollection+cleanup
- https://jira.codehaus.org/browse/GEOT-4181
- https://github.com/geotools/geotools/pull/44


GeoServer:
- https://jira.codehaus.org/browse/GEOS-5398
- https://github.com/geoserver/geoserver/pull/61

uDig:
- https://github.com/uDig/udig-platform/pull/161

Everyone else:
- switch dependency to 9.0-M0 and follow upgrade.rst
- http://docs.geotools.org/latest/userguide/welcome/upgrade.html

When: after 9.0-M0 milestone
Serously: When we get time, weekend house party?

So Saturday 17th November (to avoid everyones workday)

Provenance review
==============

- http://geoserver.org/display/GEOS/GeoServer+Provenance+Review
Please each one grab a few modules

Procedure:
- find files without headers and fix
- find files with extraneous headers and mark it as so
- check where the test data is coming from? Or do we exclude it?
- create jira issues for problems found, and link them from the wiki page

Example, very detailed:
http://wiki.deegree.org/deegreeWiki/OSGeoIncubationCodeProvenanceReviewReport
Lax one:
http://wiki.osgeo.org/wiki/PostGIS_Provenance_Review /
http://trac.osgeo.org/postgis/wiki/DevWikiProvenanceReview


User list review
================
Eternal problems
- SLD
- problems with OpenLayers
Geoserver specific and common
- REST configuration
Geoserver specific, may point to some real problem
- non-ASCII characters in layer names
Own experience about the last one
-non-ASCII in KVP queries and in filters sent through http GET
 can be very tricky to escape correctly especially from Windows


XSLT output format
================

<Fun>
  <with>
       <Functional/> programming <using/> many angle brackets!
  </with>
</Fun>

Note: feature counting XSLT forces everything to memory

Backport GWC integration fix
============================

One API change, but very important to get a working integrated GWC

Freemarker REST stuff
==================

Backport to 2.2.x once 2.2.2 is released?

Closing
======

Next meeting: Monday 26 November, 13:30 UTC

*** Note new time ***
