1 HL7 V2 Authoring and Management Tool --Presentation to IHE-PCD John Garguilo, NIST National Institute of Standards and Technology Contact: WebEx (Recorded) 30 October 2013

2 IGAMT Overview (Disclaimer) The following slides and recorded presentation (via WebEx) is for informational purposes only The IGAMT is a concept exploring NIST s prototype development effort and is not a tool/application/software available or ready for general use (at this point in time) All feedback is welcome; all software produced by NIST is freely and publically available NIST acknowledges the terrific work by Peter Rontey and hopes that such development builds upon the Messaging Workbench (MWB) and keeps Pete s spirit of collaboration and contribution, continues the pursuit of better conformance criteria and profile definition, and most importantly keeps his wish alive 2

3 IGAMT Overview (start/intro of presentation) One of the primary goals is to get documentation into specifications that leads to or enables formal implementable and testable assertions This work is part of NIST s overall HITTI architecture and we believe is a key component to help users get at more consistent and accurate implementation guides. and provide in a more automated fashion information which can be directly consumed by the test system(s) and at the core provide context information MWB For those of you familiar w/ MWB, this pilot can be thought of as building on Peter Rontey s work by providing a web-based interface and more componentized functionality; Sara Stewart (NIST Contractor) will provide further details on this point For this demonstration/session the goal is to communicate our thinking and ask for (Industry) feedback ( , otherwise) Rob and Sara have demonstrated this work at the recent HL7 WG mtgs (including a session for the Healthcare Devices Group This work is lead by Rob Snelick and many thanks to Sara for her contributions timelines for the completion or availability of this pilot is not yet established but will be dependent on the next iteration of IHE tool support (e.g., post cycle 8 for PCD) and the next Winter/Spring 2014 MU set of requirements (Jan/Feb 2014) 3

10 Messaging Workbench IGAMT Create Message profiles including XML Create Value Sets Create Data types Create Segment Libraries Create profile components x Validate attributes against standard Compare profiles Generate human readable forms of profiles and IG Provides template for IG x Condition predicate wizard x Conformance statement wizard x Modular reusable components x Deployable as web application x Download local copy of tool 10

11 Benefits of IGAMT Authors Implementers Testers Automatic validation Standardized implementation guides Machine processable profiles Templated format Standardized conformance statements Easily compare profiles, segments and data type libraries (i.e. any object). Single source publication- Automatic update of documents as changes are being made Easily view different components and sections of document as ballot discussion is happening Ballot tracking and comments (future) Standardized conformance statements Ability to create guide from profile and the profile components they choose. (Individual views of specification) Ability to automatically create own implementation profiles off of IG profiles. Ability to customize base IG to state or local requirements. Machine processable conformance statements Ability to start test tool development as the guide is being created 11

13 DEMO Wrapup 13

14 Current functionality Creation and editing of data type libraries, segment libraries and message profiles including setting of all attributes and comments These libraries integrate so that they can build upon one another, but remain separate so that pieces may be shared. Creation conformance statements and condition predicates through wizard Allows standardization of these statements towards machine processability. Creation of value sets from HL7 code tables including defining code usage. Validation of component attributes against the standard or another profile Comparison of profiles Creation of implementation guide using provided, editable template which integrates created message profile automatically Creation of printable versions of implementation guide, message profile tables (Abstract syntax and segments) and data type libraries 14

15 Future functionality Ability to import external value sets into tool Integration of value sets within Creation and integration of profile components Creation of use case and sequence diagrams and integration of those into Ballot and disposition tracking 15
