Dear All,

The CIDOC CRM was originally formulated in the knowledge representation 
language TELOS. In 1996, there was no standard available, and several 
later attempts to define a standard knowledge representation language 
have failed for many years.
At FORTH, we have chosen TELOS because it has a simplicity very useful 
for didactic purposes, and we had a scalable platform, the SIS system, 
to demonstrate applications with millions of facts (like "triples"), a 
novelty at that time.

SIS is still used to check the consistency of new CRM versions wrt IsA 
and instantiation semantics.

Because TELOS is hardly known anymore, and in order to be independent 
from any encoding, we have chosen to reformulate the logical foundation 
of the CRM in first order logic. But features of the logical form of the 
CRM still carry a part of TELOS in it.

I have the pleasure to announce that the creators of TELOS and 
applications of it have published a retrospective paper about TELOS, you 
can share with this link leading to the Springer publication:


Kind regards
