Of course it's for passing around, Copyright does not prohibit this! It
protects the content so that you don't copy and paste it in your
document and call it your own...

The geodatabase XML schema is also published, in order to facilitate

The initial message of this thread asked if shapefile is a de facto
standard. The answer is clearly yes, in that "everybody supports it". NO
implication that it is perfect, stable, open/closed...
Finally, I do not understand your final question? Open sources
solutions (captured into..)? pretty much all open source solutions
reading vector GIS data read shapefiles. check out www.freegis.org and
also http://www.gvsig.gva.es/espa/descargasw/indice.htm (select Ingles
if you want the English version)
