Re: [Bodington-developers] hibernate ~ spring ~ common core

hi Alistair

yeah LDAP is just an example in terms of 'common' vocab for things we 
could share across integrated apps

I think the first point I'm trying to raise is perhaps OSS communities 
in e-learning might agree one common layer to bind
applications together.

Our business case is for quickly resuable tools within a service 
application, such as a PLE, VLE or other learner centric ecclectic service.

Meaning you can quickly integrate our tools into your application and 
vice versa.

So while I'm not 100% sure what OID's are...
wrt to unique ID's we use GUIDS to pair between non related apps and 
distinct insitutions so we store collections of instituion ID plus 
applications user unique ID pairs against a interoperability GUID....

the idea is to to integrate more tools within another application here 
though and less identities across services...
so yes with this model, our collective 'future tetra based tools' share 
a common person id method,
or as 'de niro' put it so aptly in meet the fockers our tools are in 
[the circle of trust] :)
