Results of research into spatial issues ...

Critical Errors in OGC's GML 3.1.0	Notes on XML Schema and why GML 3.1.0 is unimplementable
Review of FeatureType Models	Comparison of FeatureType models (from standards and open source)

Standards and other gis toolkits to mine for ideas ....

OGC		Open Geospatial Consortium, industry standards body
GeoAPI	api	OGC & ISO derrived Interfaces (that we use as often as possible)
Deegree	api	Another open-source toolkit (GPL)
JUMP	api	JTS based desktop app with its own feature model
GML2	xsd	Geographic Markup Language 2.1.2 (used by WFS 1.0)
GML3	xsd	Geographic Markup Language 3.1 (used by WFS1.1)

These ideas are being actively worked on ... these usually have a svn branch and target version!

2.2	Grid Coverage Data Access	exciting development happening in conjunction with GeoAPI
2.2	Public Domain GeoTIFF plugin	A GridCoverageReader plugin for GeoTIFF files
2.2	Grid Coverage Update	Move from OpenGIS to ISO 19111
2.2	Community Schema Support and Complex Types Project page Complex schemas - Business driver examples FeatureType survey	Support for interoperable schemas, with complex properties
2.2	FeatureVisitor	Use of visitor rather then for loop allows for magic
2.2	Rendering Optimization	more data rendered faster
XXX	Map, Layer, Data and Rendering Architecture	Build a unified map, map layer, data access and (general) rendering concept based on existing concepts in GeoTools, GeoAPI and uDig. Work has started on the geowidgets project

Developer scratch pad for new and wonderful ideas ... no branch, or target version!

Proposal	Coverage Support Plans	Plans for coverage support, concocted by those who need it.
Proposal	Multidimensional Georegistered Grid	API for selecting a 2D slice from nD data.
Proposal	J2SE ImageIO in 2D	A plan for isolating grid plugins from OGC/GeoAPI/Geotools instability
Proposal	Random Data Access	allow random access to feature content (based on indexes)
Idea	GUI Architecture
Idea	Dynamic Styling
idea	Operations API	JAI for Features
ideas	Repository	Support for cross datastore opperations
Idea	Meta Information Infrastructure
Idea	World Dataset Projection	Correctly project and draw world datasets

We do occasinally finish development ... these branches have been merged onto trunk

2.0	Module Merge
2.0	New geotools homepage
2.1	WFS GML DataStore - Web Feature Server data access
2.1	Bring Back FeatureCollection - it is done!
2.1	Shapefile Index Support - look into use of index files for shapefile, first step towards Random Data Access
2.1	FeatureTypes for GML - Expanding our Feature model to deal with the full complexity of GML
