HAPI (HL7 application programming interface) is an open-source, object-oriented HL7 2x parser for JAVA.
The Message Maker Project is a collaboration effort between the National Institute of Standards and Technology (NIST) and the Health Level 7 (HL7) Standards Consortium. NIST is directing their efforts towards the development of a conformance-testing tool that automatically generates test messages for HL7 message profile specifications. 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.
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.

V3 Modeling & Methodology Tools
The repository to use with RoseTree and the RMIM Designer.
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.
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 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.
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
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.
Provides a general project for developing and managing the software and related tools used to support the development and Publishing of V3 textual content.
Sample HMD files for javaSIG and caAdapter API's.
Documentation on Java SIG API.
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.
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.
The V3 Glossary is published as part of the Version 3 Ballot Web Site. The current V3 Ballot Web Site is always available at: http://www.hl7.org/v3ballot/html/welcome/introduction/index.htm. After clicking into the V3 Ballot Web Site content pages from the Introduction page, use the left-hand navigation tree to go to Background Documents/Glossary.
The V3 Guide was created for use by members of the HL7 Working Group as a companion to the Version 3 Standard.
The V3 Substantive Change document is published as part of the Version 3 Ballot Web Site. The current V3 Ballot Web Site is always available at: http://www.hl7.org/v3ballot/html/welcome/introduction/index.htm. After clicking into the V3 Ballot Web Site content pages from the Introduction page, use the left-hand navigation tree to go to Background Documents/Substantive Change.

Vocabulary Resources
Every copy of the HL7 Vocabulary database incorporated into or distributed in conjunction with another database or sofware program must is subject to the HL7 End User License Agreement (EULA). A copy of the EULA is available at the following location:
http://hl7projects.hl7.nscee.edu/tc_include/hl7_eula.html.
Provided by the HL7 Vocabulary Technical Committee, this document provides a brief set of guidelines for specifying vocabulary for a field within HL7 fields.
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.
This is a table of external coding systems used in HL7 messages.
Appendix A of HL7 Version 2.6 contains the V2.6 Data Definition Tables
HL7-defined vocabulary domain tables have been developed for coded class attributes and are stored in the HL7 repository. A number of views have been extracted from these to produce the HL7 Vocabulary Domain Listings for the HL7 Reference Information Model (RIM). The most current Access data base for both RIM and Vocabulary is always available as a Design Repository ("rimRepos" download) from the HL7 Project Gforge site under the Design Repository Project.
You can also view the Version 3 Vocabulary on the V3 Ballot Web Site using the following link:
