Dear Sirs ,

The following links may be useful to software developers :

http://www.freedesktop.org/wiki/Specifications

The above link may be considered http version of
ftp-like page of :
http://standards.freedesktop.org/

The site
http://www.freedesktop.org/

link is directing to

http://www.freedesktop.org/wiki

but there is no explicit links to sub-pages . It is necessary to search page links on that page recursively one-by-one which some of them does not give a useful sub-link .

The following links may be useful about compatibility :

http://www.linuxfoundation.org/
http://www.linuxfoundation.org/en/Developers

http://www.linuxfoundation.org/en/LSB

for Linux Standard Base (LSB) : I think the ideas in these pages are very important
for Upward Compatibility , especially .

http://www.linuxfoundation.org/en/Application_Compatibility

Thank you very much ,

Mehmet Erol Sanliturk
