ART-DECOR in 4 bullets (2)
• ...supports comprehensive collaboration of team members within and between governance groups
• ...allows separation of concerns and different views on one single formalized documentation for different domain experts
• ...supports creation and maintenance of HL7 templates (STU), value sets, data sets and more
Heitmann, Ciangoli: Tools for the formal standards life-cycle – ART-DECOR® 5
• One of the main objectives• Separation of concerns towards a comprehensive
specification• Different views on one single documentation
• With changing focus on different artifacts• For different domain experts
ART-DECOR main objective
Heitmann, Ciangoli: Tools for the formal standards life-cycle – ART-DECOR® 6
• „Excel“-like views• Graphical

• Terminology• Link concepts to terminologies• Create value sets
ART-DECOR: tasks +definitions

Terminology
ART-DECOR: browsers + support when creatingValue Sets
Heitmann, Ciangoli: Tools for the formal standards life-cycle – ART-DECOR® 13
• Analyst, modeler, “templater”• definitions of items for messages/documents
based on data set / scenario• Links to
• The right value sets• The right message/document specification
(template)• Representing concepts with HL7 v3 templates
ART-DECOR: tasks + definitions
Heitmann, Ciangoli: Tools for the formal standards life-cycle – ART-DECOR® 15
• Re-usable blocks• Semantics clear• Use in many contexts (scenarios) with link to
concepts and terminologies• “Focus” more clear• Make specification and implementation of
messages / documents “much easier”
Advantages of “templates”

• Building Block Repositories with various “standard” templates and value sets, e.g. C-CDA R 1.1 and 2.1, CCD 1, epSOS, IHE
• ISO schematron generator• works with open and closed templates and multiple
languages
• RESTful services to get various artifacts, e.g.• Terminology services: Value Sets• Templates, derivatives
Most important Featuresof ART-DECOR
Heitmann, Ciangoli: Tools for the formal standards life-cycle – ART-DECOR® 24
ART-DECOR in Europe
• Shared repositories with collection of artifacts• Template Repository (building bocks for clinical
document definitions) and Value Sets (code lists)• Sharing artifacts between countries has already started
by Germany, Austria, Netherlands, Poland, Switzerland
• ART-DECOR specs à Input for Testing Tool
