ANNC: java kernel implementation

[Thomas Beale <thomas@deepthought.com.au>]

Dear all,

the initial release of a java reference kernel for openEHR is available. 
The project page is at 
http://www.openehr.org/repositories/kernel_java-dev/latest/project_page.htm. 
This work has been carried out by the Swedish company a-code, led by 
Rong Chen and Göran Pestana. See 
http://www.openehr.org/projects/t_projects.htm for further information & 
links on a-code. We are indebted to the team for donating their work as 
open source to the openEHR Foundation, which really means of course, to 
the openEHR community.

The idea of a "kernel" in openEHR is a small but sophisticated component 
which implements the reference model (RM) and archetype model (AM) in 
order to actually use archetypes at runtime to build and validate data. 
It is the key component in many openEHR services, and central to the 
archetype method.

We are aiming for this implementation to become the openEHR reference 
implementation of the kernel for the Java language. The work is 
continuing jointly between a-code and the CHIME team at UCL, including 
Nathan Lea, Yin Su Lim, with some project management provided by me. 
Other developers are invited to express interest.

The project is run according to the openEHR Technical CM Plan 
(http://www.openehr.org/repositories/spec-dev/latest/publishing/CM/CM_plan.pdf). 
Community feedback can be in the form of discussion or Problem Reports, 
to report bugs or suggested enhancements 
(http://coruscant.chime.ucl.ac.uk:8200/openEHR_Collector/projects/reference_implementations/javakernel/PR/folder_contents). 
The development team itself uses Change Requests 
(http://coruscant.chime.ucl.ac.uk:8200/openEHR_Collector/projects/reference_implementations/javakernel/CR/folder_contents) 
to document the changes it makes on the software base; these can be 
viewed by anyone in the community. We are working on various PR and CR 
reports.

We believe this forms an important initial step toward the reliable 
health computing platform of the future, and we encourage Java 
developers to work with the software and provide feedback.

Technical note: developers should consider using BitKeeper to access and 
synchronise the code. See the openEHR BitKeeper pages 
(http://www.openehr.org/developer/t_bk_um_top.htm). BK is free for open 
source use.

For discussion of this software, PLEASE use the 
openehr-implementers@openehr.org list.
