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 toolkit (GPL)
JUMP	api	JTS 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. (used by WFS1.1)

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

2.2	December
2.2	November	Release of M2!
	Feature Model Design	Discussion resulting in a propsal related Support of Complex Content but who knows? letter of support for the ComplexDataStore project
M3	Events for Styles	Event system for styles, for user interface development. Updated javadocs to SLD 1.0
M3	Random Data Access	allow random access to feature content (based on indexes)
2.2	January
M4	Multidimensional Georegistered Grid	API for selecting a 2D slice from nD data.
2.2	No schedule, on branches!
	Community Schema Support and Complex Types	Support for interoperable schemas, with complex properties
	ComplexDataStore project	Complex schemas - Business driver examples FeatureType survey ApplicationMetadataAndComplexTypes
	Rendering Optimization	more data rendered faster
	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
	Public Domain GeoTIFF plugin	A GridCoverageReader plugin for GeoTIFF files

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

Idea	CatalogAPI	Bring GetServer Data, GeoTools registry and UDIG Catalog into a shared codebase
Proposal	Community Discussion	Plans for coverage support, concocted by those who need it.
Proposal	J2SE IIOMetadata	A plan for isolating grid plugins from OGC/GeoAPI/Geotools instability
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
Idea	3D Geometry and Rendering ideas	Use the same 1D/2D/3D geometric objects as basis for both 2D and 3D rendering (Java2D/Java3D/other?)
Proposal	Topology Framework	A proposal for a topology framework which could bind FM and JTS in both uDIG and GeoServer environments

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

2.0	New geotools homepage	Done!
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
2.1	Grid Coverage Update	Move from OpenGIS to ISO 19111
2.1	Grid Coverage Exchange Design	GridCoverage interface based on OGC Grid Coverage Exchange spec, in conjunction with GeoAPI
2.2	HSQL DataStore	Done, Merged, released
2.2	FeatureVisitor	Used for aggregate functions, see next item for motivation
2.2	Color Brewer	Code produced by James and Corey (thanks Penn State)
