Giovanni,

Yes you have, in areas to consider terms, you have covered things well.

I think now we should start to drill down towards potential properties and
some examples thereof.

Your emphasis of the possible technical facets of access & use, raises a
question that I believe will occur several times as we move forward.

When is a descriptive need a consequence of an item being part of an
archival collection, and when is just part of that item whatever the
context?  If the item is an 8 inch floppy disc, the need for a certain
types of drive and software should be descriptive requirements anyway.  In
an archives context however a relationship to such resources, in the
current or other archives, should be describable.

Enjoy your vacation!

~Richard.
