The openEHR Specifications Editorial Committee (SEC) has published RM Release 1.1.0 today.

Change-log | Issues fixed

This release brings a number of important improvements to the reference model including:

• the new DV_SCALE data type, supporting scales/scores containing decimal numbers;
• addition of a preferred_term field to the coded text data type;
• addition of archetypeable meta-data to Folder objects;
• addition of unlimited Folder hierarchies to an EHR;
• addition of free meta-data field to Feeder system audit, to aid integration;
• added null_reason field to ELEMENTobjects (i.e. any archetype leaf node);
• support any units system and units display text in Quantities.

We hope this proves useful for the community, and would like to thank all the implementers for the feedback that led to this release, as well as the SEC members and others who helped create it.
