[higgins-dev] RE: [ecf-dev] Agenda for next conference call

Hi Scott,

You sent this email on Sept 9 (that I can't find in the higgins-dev archives
for some reason, else I'd have linked to it)...


Hi Jim and other Higgins'ers

A thought/suggestion:

In IDigitalSubject you have a method:

String getUniqueID()

I would suggest that you consider generalizing this to allow multiple types
of ID (i.e. other than String), by having a new ID interface

ID getUniqueID()

In ECF we do this and ID is an interface that extends (and therefore has a String getName()) method, and
extends IAdaptable, so that adapters for IDs can exist.

In ECF, we use a plugin org.eclipse.ecf.identity that declares ID (see
identity package javadoc here:
ntity/package-frame.html).  The semantics of IDs are assumed to be simply a
unique ID (usable for uniquely identifying users, processes, roles,
services, digital subjects, etc., etc).  Obviously since it extends
Principal it also serves as a principal within JAAS.

We've found that having ID be defined as an interface and providing an
extension point to allow people to define custom types of ID (rather than
referring directly to a String) has been of use for ECF, and it could also
be of value for Higgins.  So it might be of use to think about having
Higgins IDs potentially have more general structure than String.

Just a thought of potential reuse across projects (some notion of an
abstract unique identifier...aka ID).



The Higgins team is still considering this proposal as a change to the IdAS
API. We've only given it a passing look so far, but we'll circle back to it.
So WRT to ECF the event that we do agree to use the ID
interface, it would be good to have it separated out from other ECF stuff.
