Specification Project

Overview

The specifications project in openEHR performs the requirements, analysis and design work necessary to product the openEHR technical specifications, i.e. the Reference Model, Archetype Model, Service Model and languages, such as ADL (Archetype Definition Language) and AQL (Archetype Query language). The structure of the specifications is described in the Architecture Overview.

How To...

Have a local up-to-date copy of the documents on your own machine

Just follow these steps using your subversion client:

• create a directory where the documents will be saved, e.g. somewhere/openEHR/specifications
• using TortoiseSVN or any other Subversion client, checkout http://www.openehr.org/svn/specification/TRUNK/publishing/ into the new local directory. (See Subversion pages if you don't understand this).
• the file index.html is top of the document tree, and will allow you to access all documents offline
• updating to the latest is as easy as telling the subversion client to update that directory (this can be automated with a simple script)
