Hi Randy
I guess it does so far at least. I guess there will only be a few back end openEHR servers in the future, one or two of which are likely to be open source. The idea is that the query layer is further away from the implementation layer than is usual for a health care system. The way the openEHR data can be stored is still an experimental science. Ocean has an AQL parser which then queries the openEHR repository and is now optimised in a number of ways. Some of these are independent of the storage mechanism entirely.

Does this imply that each implementation of openEHR is sufficiently different from others as not to allow for easy sharing of such things as search or storage technologies?

It's probably right under my nose on your specification/release page. Also, do you have any references describing the AQL processor? Did you write that from scratch?? It would seem that the AQL processor would indeed function as a formidable DBMS in its own right, at least with regard to reads, capable of managing AND/OR logic trees and serving up flat "tables" of joined data structures like any RDBMS.
