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
