RE: Serialisation of openEHR Models

Last week I attended to an Ed Hammond's talk in Argentina, and in his presentation he mention a new concept to reach true interoperability: the data element.

Please see page 13-14: http://www.hospitalitaliano.org.ar/archivos/noticias_archivos/11/Jornadas2011/11_11.01-03-Hammond-Interoperability-BuenosAires.pdf

I asked him why this sounds so much like openEHR archetypes and why don't reuse this concept instead of creating a new one (or at least renaming it). He told me "everyone want his own standard", that was very sad.

Besides that, what I see (and many people on that room that know what is an archetype) is a validation of an important figure on HL7 that archetypes work, do the job, and are necessary for interoperability. So, I think HL7 is very interested on archetypes right now.

I hope that soon Mr. Hammond could do a presentation on standarization that show the best of the breed instead of reinventing/renaming the wheel.
