Two Models: Cathedral and Bazaar
Open Source Geospatial Foundation3Gary Lang - OSGeo Treasurer, MapGuide Project
Autodesk is a Cathedral?
Open Source Geospatial Foundation4Gary Lang - OSGeo Treasurer, MapGuide Project
“Cathedral”
Webster says:
“The principal church in a diocese, so called because in it the bishop has his official chair (Cathedra) or throne. “

Our Bishop?

Successful closed source – The Cathedral

Successful open source – The Bazaar

The Geospatial Bazaar

What causes migration of a Company & its Code base from Closed to Open Source?
Open Source Geospatial Foundation10Gary Lang - OSGeo Treasurer, MapGuide Project

Context
Open Source Geospatial Foundation11Gary Lang - OSGeo Treasurer, MapGuide Project
Standards Facilitate, drive migration
POSIX, Unix culture -> Linux
HTTP -> Apache
SQL, ODBC, OGIS -> PostGIS
GML, WMS, WFS -> MapServer

Then came Google Maps

AND Google Earth Brings “Mirror Worlds” to the Masses

Mirror Worlds
“Imagine looking at your computer screen and seeing reality – an image of your city, for instance, complete with moving traffic patterns, or a picture that sketches the state of an entire corporation at this second…. These will soon be available to anyone.

Open Source Geospatial Software and Standards
Standard APIs have facilitated growth.
Open web services including OGC WMS, WFS,
MapServer, Mapbender
OGC Simple feature spec for SQL (SFS) PostGIS/PostgreSQL MySQL/MySAM spatial

Geospatial Open Source Takes Off
Open Source Geospatial Foundation23Gary Lang - OSGeo Treasurer, MapGuide Project
Autodesk goes Open Source
Why we did it
Our users wanted it (we’re too slow)
It makes business sense for MapGuide
It makes business sense for Map
It makes business sense for Topobase.

Standard APIs created commodization opportunities for web mapping
Drives closed source genres into open source genres
Context (commoditization) is fertile ground for open source
Standard APIs are closely associated with context, and move software genres into context from core.
As standard geospatial APIs emerge (ISO, OGC, Google Maps 2.0,..) open source geospatial will become more ubiquitous.
