Problem statement

The notion of a 'system' has not been clearly defined in openEHR to date, and has changed since the original specifications were published. 

We need:

• a definition, that takes account of cloud, multi-tenancy, openEHR solutions used as gateways or caches and so on
• definition of 'system_id' in the specs
• guidance on use of system id in version ids, REST APIs and other contexts

It is proposed to add content developed here to the Architecture Overview in BASE release 1.0.4
