ART-DECOR 1.0 is released!!!
ART-DECOR is the open-source cooperation environment supporting one or multiple governance groups each governing their own projects supports setting up datasets with vocabulary bindings, value sets, scenarios, and message/document definitions (templates). It fully implements the HL7 Template ITS read/write/prototyping of templates and the building block repository (BBR) feature for re-usable artefacts such as value sets and templates. See Releases for details.

Welcome to

DECOR (Data Elements, Codes, OIDs and Rules) is a methodology to capture the data needs of caregivers in terms of datasets and scenarios and use it to generate various artefacts: documentation, value sets, XML instance validation, generation and processing support, and test tools etc.

DECOR allows to iteratively improve recorded data and link together input from various experts with different background knowledge: caregivers, terminologist, modelers, analysts and interface/communication specialists.

Ds.pngSc.png For caregivers DECOR mainly registers datasets with concepts, data types, allowable value ranges, identifications, codes, examples and business rules etc.

Cd.pngId.png From that base, terminologist can add the appropriate codes, associate caregiver concepts with coded concepts and create and maintain the value sets to be used. Typically also namespaces, identifiers, URIs and OIDs are assigned.

Tm.png Modelers, analysts and interface/communication specialists add the technical representations as e.g. HL7 CDA templates, HL7 v2 or v3 message definitions or HL7 FHIR or IHE profiles. During that design phase and also in the following implementation and production phases the tool allows comprehensive validation and testing.

The underlying DECOR data format is XML. The generation of HTML-, PDF- and Wiki-based documentation and XML-materials like validation and test environments is possible through a release and archive management function and transformations with stylesheets. The technical artefacts like templates and value sets can be used as input for test suites like IHE Gazelle ObjetcsChecker. Easy consistency checks across all artefacts can be achieved, CDA-based template definition can be verified to be standard conformant with the underlying CDA standard.


ART (Advanced Requirement Tooling) is the DECOR user interface to create and adapt DECOR files, and to generate artefacts from DECOR files. ART is based on the eXist-db XML database, XQuery and Orbeon XForms.
