Hello, I am currently work on implementing the reference model in java. I have noticed an issue that I would like to get resolution on. While looking over the RM.DATA_TYPES.BASIC package in RM.DATA_TYPES(Revision 1.8) and comparing it to the HTML Model Tree, generated by Eiffel, I noticed something. In the model tree there is a data type called CANONICAL_FRAGMENT which is not in the 1.8 Revision. The CANONICAL_FRAGMENT has a description of "Abstract parent type of all concrete data value types". What is the pupose of the CANONICAL_FRAGMENT and what is the class desctiption? Also, what is the projected timeframe on updating the documentation to reflect this and any other changes?
Thank you for you time. Mike Engel engelme at vvm dot com P.S. I am very impressed and thankful for all of the work that OpenEHR Foundation and Community is giving to the international community. - If you have any questions about using this list, please send a message to d.lloyd at openehr.org
