There is an open source ADL to XML conversion library for .NET written in c# located at http://www.openehr.org/svn/knowledge_tools_dotnet/RELEASES/BlueChina/XMLPars er. This is used by the Archetype Editor to generate a pure XML representation of the ADL file via the ADL_Parser so that it can create a canonical xml representation of the archetype model for hashing purposes. The XML displayed and files generated directly from the Archetype Editor uses a different (legacy) mechanism and is not as reliable as that produced by the conversion library, the result is slightly different XML output. We just have not had enough volunteer time to replace this legacy approach within the Archetype Editor.
If anyone need assistance in using this conversion library I can provide an NUnit test library that shows how it can be used, or you can sift through the Archetype Editor code if you prefer VB. We actually have a publishing tool using this library that can run a batch process against an entire Archetype file repository that can be run within an auto-build process and committed back into svn. This is how the XML archetypes on openEHR used to get generated prior to CKM. I am not sure if CKM supports XML output of archetypes as yet but if it is felt that not having archetypes available in XML is holding back openEHR adoption then I am sure this can be put on the change request list for prioritisation.

Most modern UIs follow a Model-View-Controller <http://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller> approach. For PatientOS Archetypes provide the data elements. The relationships and constraints within the archetype data elements is implemented in our model. We have different views - fat client, web client which are implemented through controllers written in java or javascript. Atttempts to push everything into the archetype definition would create a complex beast which would defeat KISS principal. As a side note I also think the ADL files is hampering adoption - not for us as there is a Java parser. Since everything that is the ADL must be expressable in XML (otherwise interoperability of the definitions would be problematic) - why have both - XML is ubiquitous and I think the benefits of readibility of an ADL file is no longer needed since there are tools which replace it - how many people read an ADL file any more? -- Gregory Caulton Principal at PatientOS Inc. personal email: caultonpos at gmail.com http://www.patientos.com corporate: (888)-NBR-1EMR || fax 857.241.3022 -------------- next part -------------- An HTML attachment was scrubbed...
