So I've been playing around trying to model the architecture and I'm trying
to understand how to model trust. Specifically I'm working with a simple
model
* EntityMetadata
- carries the actual metadata
* Location
- a place where metadata resides
* Authentication
- a reason to trust metadata
Right now my feeling is that EntityMetadata is associated with 1 or more
Location (an EntityDescriptor can come from several places) and that a
Location is associated with 0 or more Authentication instances, i.e trust
in metadata is dependent on both what is used to establish technical
trust (eg a signature) aswell as the location from which the metadata
was obtained.
Does that sound reasonable?
Cheers Leif
