Dear All,

It is my pleasure to announce that the CRM-SIG has produced, with all 
your active contributions, help and support, the new official version of 
the CIDOC CRM base: CIDOC CRM 7.1, available at: 
http://www.cidoc-crm.org/Version/version-7.1 .

The last official version, 5.0.4, dating back to the year 2011, formed 
the basis for the update of ISO21127 to ISO21127:2014. Since then, we 
have worked diligently to improve the expressive power and quality of 
the CIDOC CRM as a base model and have widened the scope by encouraging 
and approving compatible extensions.

For CIDOC CRM 7.1, the entire introductory text has been revised and 
partially rewritten in order to serve as a precise definition of the 
intended function and theoretical foundations of the model and as a 
minimal didactic introduction. The model itself has been substantially 
enhanced in multiple directions.

First, it has been redesigned to provide a) an effective model for 
relating things and phenomena to space and time that supports 
interoperability with geo-referencing standards and GIS applications. In 
order to support this new functionality, a few more classes and nearly 
50 more properties have been added to the standard.

Second, major effort was put improving and stabilizing the logical 
consistency of the standard, introducing first order logic expressions 
to complement the formatted textual declarations.

Third, the model has been streamlined by deprecating a few constructs 
that can be replaced easily by other parts of the model or which offered 
little practical value. These efforts were carried out in order to 
simplify implementation and improve model comprehensibility. While this 
creates some minor backwards incompatibility, the SIG preferred this 
over indefinitely carrying forward backlog of some initial decisions 
that were based on a different anticipation of the model’s future 
applications.

Finally, extensive and valuable editorial work by members of the SIG to 
apply consistent style rules and templates and to remove typos and 
difficult to understand phrases in the text. An emphasis in this work 
was to improve the quality of examples provided. Explanations and 
literature references were added to the real world examples for classes 
and properties so that readers can have full access to their context. 
Where examples had been missing, they have been added wherever possible. 
While over a year of effort has gone into this task, further corrections 
may arise as the document is examined by the community. The improvement 
of the document is an on-going process.

CIDOC CMR version 7.1 will be the basis for submission to ISO as a new 
community draft.

The semantic content of this version should, therefore, be regarded as 
stable, and as a basis for updating implementation and translations to 
other languages. As feedback comes in, minor editorial corrections may 
still occur which should not affect implementations and translations. 
The version will be presented in more detail in the next virtual SIG 
Meeting March 8, 2021, which I hope, many of you will attend.

Best wishes,

Martin
