Philips Research, March 11, 2010 3 MIF: What Is It? (1) MIF = Model Interchange Format Can be viewed in different ways: As a set of XML formats used to support the storage and exchange of HL7 version 3 artefacts as part of the HL7 Development Framework. As a (meta)metamodel, i.e. as a metalanguage that is used to define the HL7 version 3 standard and its constituent artefacts. The definition of the MIF is a task of the HL7 Tooling Working Group. MIF 2 definition is not stable yet; latest version can be downloaded from http://gforge.hl7.org/gf/project/mif-schemas/frs/. http://gforge.hl7.org/gf/project/mif-schemas/frs/

(2) HL7 Version 3 artefacts that are defined in MIF: Analysis related artefacts such as –domain analysis model, story board, glossary Static model related artefacts, such as –static model, derived static model, serialized static model Dynamic model related artefacts, such as –interaction, trigger event, application role Vocabulary related artefacts, such as –vocabulary model, code system, code system supplement Data type related artefacts, such as –data type model library Conformance related artefacts, such as –conformance profile, interaction profile Publication related artefacts, such as –publication, structured document, freehand document

Application programmers use these tools and the code generated from these meta-objects to build applications. So, it’s only a special breed of programmers that should ever see MIF … "No human should ever see MIF, except for programmers, and those aren't human anyway." Grahame Grieve (adapted from Tim Berners Lee).

What you need: 1.A way to read MIF files. –Use existing tooling (Eclipse) or generate it from the MIF schemas 2.A proper understanding of the MIF constructs. –Unfortunately there is not much documentation … It helps to read and process MIF instances in terms of strongly-typed classes generated from the MIF schemas. Tools such as xsd.exe (for.NET) generate such classes.
Philips Research, March 11, 2010 9 MIF: How We Used It (1) MOM object model of MIF was generated from the MIF schemas, including read and write methods. MIF files are read as instances of the MIF model and mapped to object models. Applications are built using C# classes generated from the object models.
