These implementation profiles are created by a consensus process among professionals; the profiles are based on existing messaging standards such as HL7 and DICOM. Conformance to IHE profiles is tested by means of testing tools and a live system-to-system testing event called the Connectathon. A European connectathon took place in 2007 in Berlin, Germany.... http://www.ringholm.de/docs/00830_en.htm http://www.ringholm.de/docs/00830_en.htm Sun, 02 May 2010 07:00:00 GMT rene.spronk@ringholm.com (René Spronk) Traditionally information architects model information using a closed world assumption (when one models using relational or OO principles). Increasingly www-inspired description languages (e.g. OWL) are used, which are based on open world assumptions. These two worlds will have to be bridged to take full advantage of the new possibilities.... http://www.ringholm.de/column/HL7_OWL_adding_openness_to_a_closed_world.htm http://www.ringholm.de/column/HL7_OWL_adding_openness_to_a_closed_world.htm Tue, 09 Feb 2010 07:00:00 GMT rene.spronk@ringholm.com (Rene Spronk) The Model Interchange Format (MIF) is a set of XML formats used to support the storage and exchange of HL7 version 3 artefacts as part of the HL7 Development Framework.
