Good answer. It is really open enough for practical purposes.
I have developed my own C++ shapefile library and integrate it in my projects
from Nov 2000.

Neil,
While Shape is not "open" in the sense of having been specified by a
neutral standards process or community consensus, for practical purposes
of writing software it has proven to be "open enough". One of the
reasons for its current ubiquity is that it has proved easy enough for
other vendors and developers to integrate into their software.
In answer to your open source question:
- As a developer, you could use shapelib http://shapelib.maptools.org/
for your C programs, or geotools http://www.geotools.org for your Java
programs.
- As a user, you could use ogr http://ogr.maptools.org/ for format
conversion to and from shape. Or you could use tools provided by your
software supplier. For example, PostGIS ships with shp2pgsql for data
loading. Oracle Spatial ships with shp2sdo, same idea. The flip side of
the format ubiquity in public data is its ubiquity in software support.
Yours,
Paul
