[OGSA-D-WG] Teleconference Minutes, 8 June 2007

[Dave Berry]

OK, I've uploaded a new version.

- I've revised the section on cache services as I described yesterday.

- I set the language to US English and fixed some of the spelling
accordingly.

- I added most missing definitions to the Glossary.  These included the
ones we discussed online and in telcons.  I also attempted some new
definitions - feel free to review and criticise them.  I suggest we
don't really need definitions for "consumer" and "storage management"
(partly because I couldn't think of any definitions beyond the obvious).

Dave.

Dave,
      Take the token just now. I'm kind of swamped and have not had 
time to do anything so you might as well incorporate your changes. When
you are done let me know and I'll try to see if I have time. Hope you
are better ....

Mario
