Re: DB structure: Dialog of Texts (DoT)

Any object that is potentially changeble should have an ACL entry.
Someone
may want to edit a text.. Adding, deleting texts with DoT may be
assumed as
'edit' permission on DoT.
My first answer is "No". I mean, changes to DoT must be matter of policy
as ones to courses and other UMOs. Our most general approach is that
"Authorship" is the most untouchable, protected, sacred, etc. thing.
Thus, one can use, even edit a UMO for ones own purpose, BUT must always
attribute it to the original author. Consequentially, nobody can edit MY
UMO without my permission! This is a privilege of assigned co-authors
(the later can also be general public, if the author so desires).
Cross-reference would be added. I just need to understand, is it like
'Also
take a look at the following texts: {list of texts here}' ..
Not quite. DoT is purposely assembled collection to provoke thinking.
This is its main if not the only idea. DoT will probably be used in many
other ways when UU goes life, but its fundamental idea is the one:
provoke thinking.

What I mean is that single text within DoT may not actually be
separable.
I.E. one cannot reference separate text, and thus there is no need to
have
separate ACL. Access to whole dialog object applies to separate pieces
of it as well.
Also, important part of DoT functionality is cross-referencing between
texts.
How is this reflected in our database schema? (Take a look at
Model-layer
to see sketch of what is intended).
