External Tools

ART-DECOR

DECOR (Data Elements, Codes, OIDs and Rules) is a methodology to record the information model used by health professionals. DECOR uses this model to generate various artifacts: documentation, XML- and test-tooling, etc. With DECOR it is possible to improve the recorded information model by generating and resolving issues per item. DECOR registers (amongst others) datasets, datatypes, valuesets, codes, identifications, and business rules. The underlying data-format is XML. Generation of HTML-documentation and XML-materials is possible through transformations with stylesheets.

The messages can be used to test systems for conformance. A prototype of Message Maker is available at this site. All NIST produced source code, documents, and associated products are in the public domain. Message Maker is a work-in-progress, as such, not all planned functionality is implemented; feedback on its design, feature set, and usefulness is welcomed.

OID Registry

An OID is a globally unique string representing an identifier in a form that consists only of numbers and dots (e.g., "2.16.840.1.113883.3.1"). According to ISO, OIDs are paths in a tree structure, with the left-most number representing the root and the right-most number representing a leaf. OIDs are the preferred scheme for unique identifiers in HL7. The tool allows you to review, search and report on OIDs as well as request or obtain an OID.

UML Profile for MIF Static Models

The solution selected for the FIRST HL7 TOOLING CHALLENGE: Produce a UML Profile for MIF Static Models - This is a task so that other modeling tools have a chance to be configured to understand MIF

  • Document a UML Profile for the semantics in the MIF representation of the RIM and other derived models - identifying those concepts that cannot be expressed in UML Profile language to provide to OMG for possible extension of UML
  • Using the resulting UML Profile, adapt Enterprise Architect to express the proper HL7 stereotypes as a proof of concept.

UML Tooling

This project contains UML modeling tools that support development of HL7 standards. It includes a UML profile for HDF (additional HL7 metadata added to UML models), importing MIF to UML, and Eclipse UI extensions for HL7 modeling.

V2 & V3 Mapping Tools

Eclipse-based tools for semantic mapping and data transformation, with extensions for HL7 V2 and V3. They can map, translate and test HL7 V2 to other data formats, or V3 to other data formats, or V2 - V3 in either direction.

V3 Modeling & Methodology Tools

Design Repository

The repository to use with RoseTree and the RMIM Designer.

PubDb

The Version 3 Publishing Database is maintained by the V3 Publishing and Tooling Work Groups. It is periodically updated to support publishing changes and to incorporate feature changes and updates. Please note, however, that V3 Editors and Publishing Facilitators wishing to work on established V3 content should download the appropriate domain pub db from the V3 'Source of Truth' ballot archive. The 'Source of Truth' files for past V3 ballots are located here: http://www.hl7.org/v3ballot/html/. Those wishing to download the latest version of an empty V3 pub db can do so from the HL7 G-Forge site at: http://hl7projects.hl7.nscee.edu/frs/?group_id=34.

RMIM Designer Current

The HL7 RMIM Designer is a graphic designer that supports the design of HL7 static information models. The Current variant of this tool is built upon customized "templates" in Microsoft Visio; a suite of Visual Basic software that runs in the Visio application space; and modules (DLL's) from the RoseTree program. The tool provides an interactive design capability for HL7 RMIMs, and is programmed to use data from the RIM, Vocabulary, and Data Types specifications to enforce the model design rules expressed in the HL7 V3 Methodology.

RoseTree

RoseTree is a donated Visual Basic (VB) application that functions as an interface to the HL7 repository for several other applications, including the current RMIM Designer, the PubDb and the V3 Generator (for which RoseTree creates source files). In addition, it provides a browser for the HL7 RIM and Vocabulary; builds RMIMs and HMDs from Visio designs; and manages the repository storage of these.

V3 Generator

The V3 Generator accepts the XML expressions of an HMD and, through a series of transforms, generates HL7 artifacts including: Static schemas, Interaction schemas, HTML table views, CSV files for Excel views and MIF files for static models, data types, and vocabulary.

V3 Utilities

HL7 Development Framework (HDF)

The HDF project is intended to define and maintain the methodology applied by all the committees for project initiation, requirements analysis, standard design, implementation, standard approval process, etc.

HL7 V3 Publishing Tools

Provides a general project for developing and managing the software and related tools used to support the development and Publishing of V3 textual content.

PubDb Manager

The PubDb Manager is a widget created to facilitate the alignment of artifact status across PubDbs and Design Repositories, and the merger of PubDbs, both across domains and within a domain.

Reference Information Model (RIM)

The Reference Information Model (RIM) is the cornerstone of the HL7 Version 3 development process. An object model created as part of the Version 3 methodology, the RIM is a large, pictorial representation of the HL7 clinical data (domains) and identifies the life cycle that a message or groups of related messages will carry. It is a shared model between all domains and, as such, is the model from which all domains create their messages. The RIM is an ANSI approved standard.

Mayo Lexical Grid

The Lexical Grid Vision - a distributed network of terminological resources. Currently, there are many terminologies and ontologies in existence. But just about every terminology has its own format, its own set of tools, and its own update mechanisms. The only thing that most of these pieces have in common with each other is their incompatibility. This makes it very hard to use these resources to their full potential. We have designed the Lexical Grid as a way to bridge terminologies and ontologies with a common set of tools, formats and update mechanisms.
