Open Source StrategyNexJ Systems Inc.


NexJ Open Source Business Objectives

Gain entry into the Healthcare vertical through developing relationships with healthcare providers and other software companies through the open source community.

Partner with other companies and projects to tackle some of the very complex tricky technology issues involved in creating and sharing health data and an electronic health record

Combining people centered model with NexJ Model Driven Engineering Technology with other open source projects and products

Establish NexJ as global leader in model driven engineering technology.

Market the NexJ Model Server platform as a platform for enterprise software development and deployment.

Promote adoption of the NexJ Model Server platform.

Sell value added commercial components, products and services around the open source offerings.


NexJ Open Source Strategy

Open Source NexJ Technology to run in an open source environment to enable:

Working with other open source projects such as Eclipse Modeling Framework (EMF), Model-Driven Health Tools (MDHT), NHIN Connect, etc.

Creating research, proof of concept and pilot implementations that support hundreds of concurrent users.

Create commercial scale product offerings based on the open source code base that enable:

Support for commercial databases, J2EE containers, and other commercial software products and platforms

Massive scalability to tens of thousands of concurrent users and beyond.

Enterprise class management and monitoring Advanced Studio features such enhanced editors, debuggers,

model visualization tools, etc.


NexJ Commercialization Strategy Create Commercial Product Offerings on

top of this open source base: NexJ Development Server

• Manages development process• Allows editing and publishing the model at runtime

NexJ Enterprise Model Server• Commercial HJ2EE Container Support: WebSphere, BEA

Weblogics• Clustering and Load Balancing Support• Enterprise Management and Monitoring Modules• Highly tuned commercial database adapters: Oracle

and SQL Server NexJ Studio

• Improved Editors • Interactive Debugger Support

Commercial Products and Models:• NexJ Universal Health Connector

– Enhancements to OpenHealthConnector running with NexJ Enterprise Extensions

• NexJ Health Portal• NexJ CRM for Finance• NexJ Finance Portal• NexJ Mobile Solution for BlackBerry

Open Source Timeline Update

Q1 2009: Not For Commercial Use NexJ Model server and Studio

Q2 2009: NexJ Integration and MySQL persistence adapters

Q4 2009 Committed enhancement to EMF project to enable support

for evaluation of constraints using OCL and NexJ Scheme Published NexJ Scheme Engine as an independent open

source project.

Next Steps Release OpenNexJ Model server code to the OHT Platform

Project in Mid Q1 2010. Release NexJ Studio Lite as a free download. Release Reference Implementations: Patient/Provider

Registry, Open Health Connector.


OHT Platform Boca Chart - 2Q2009

- Suitable architecture to use current components with path to open source

- IHE and HL7 compatibility- Healthcare document/message standards- Existing modeling projects

Dependencies

Packaging Editions

- Working with Mohawk on:

- improved HL7v3 support

- Registry services- Architecture for distributed

service orientated architectures- MySQL persistence adapter 1st

open source code contribution.- Need to get to the details of

defining how to consume Semantic and Clinical Models

Content- Need to describe path to open

source- Several services required to be

useful- Need reference

implementations- Pressure from current

implementations- Large number of changing

specs for modeling of various types.

- Semantic modeling

Pressures/Exposures- Project description and outline- NFCU version of posted with

Tutorial

- MySQL persistence component and integration adapters released

- NexJScheme and enhancements to EMF released
