I've also read and used the "Using the Open Systems Toolkit..." manual.
My opinion falls between David and Jim's.

The system as a whole is well though out, and makes developing new
types (relatively) straightforward.  I implemented a variant link
with multiple resolution texts (it tries each in turn until one 
successfully resolves, and returns the linked object).

However, the manual is very slow reading.  It's a good reference but
not easy to jump into.
