What is OpenEAI?

The OpenEAI Project endeavors to discover and document the controlling dynamics, principles, and practices of enterprise application integration and service oriented architectures and to present, implement, and promote those findings. The OpenEAI Project presents findings in the form of the OpenEAI methodology and OpenEAI software for implementing integrations.


What we will cover

• Demonstrate the OpenEAI sample enterprise with example integrations and services representative of sites using OpenEAI

• What is OpenEAI?

• Impetus for OpenEAI

• How the OpenEAI project was initiated

• Some benefits of using OpenEAI today

• Some long-term and potential benefits of using OpenEAI and participating in the project

• Commercial implementations of OpenEAI integrations and services

What is OpenEAI?

• A methodology for analyzing and defining integrations and enterprise services

• A integration message protocol using XML format that provides the specification for enterprise messages as well as the expected, general behavior for applications that process these messages.

• A suite of standards-based foundational APIs that provide the building blocks for integrations, service implementations and general application development

• An open source project with six departments that focus on documenting OpenEAI technology and concept as well as providing example implementations and production-quality reference implementations


What OpenEAI is NOT• A set of standard message or service definitions

(standards bodies like PESC, IMS, SIF, and others do that work, OpenEAI uses and interfaces with these standards and provides a strategy for implementing any integration where standards do not exist)

• Packaged integrations and services

(the project produces foundation components and reference implementations, and there are many open source, free, proprietary and commercial integration and service implementations using OpenEAI)


OpenEAI Departments

1. Methodology

2. Message Object API

3. Application Foundation APIs

4. Message Definitions

5. Reference Implementations

6. Deployment and Administration


How OpenEAI came to be1. Organizational nature of the University of Illinois

• Large, decentralized organization with three campuses; 66,000 students; 20,000 employees; 964 departments; annual operating budget of $3.5 billion

• Four different departments dedicated solely to IT at the campus and University administration levels and hundreds of active IT groups in the University departments

• Many heterogeneous platforms• Many disparate systems: approximately 130 enterprise-

wide systems; hundreds of campus-specific academic and administrative systems; thousands of academic and administrative systems in University departments

• Business process improvement and cost/risk avoidance• ERP implementation provided an opportunity to rebuild

technology and integration infrastructure• Emphasized dramatic nature of shift from proprietary point-

to-point interfaces to standards-based messaging


2. Why did we build our own?

• Cost savings vs. proprietary approach• Proprietary everything! Terminology, tools

languages…• Much of the same work had to be done even with a

proprietary solution. • UI is a large organization and we couldn’t ask all our

departments to purchase a very expensive license and maintain a very complex integration broker themselves

• Intellectual savings. By developing software and methodologies based on standards, we’re allowing our staff to concentrate on a set of core concepts supported by more than just one company.

How OpenEAI came to be


3. Why and how did it turn into an Open Source initiative?

• After discussing what we had done with our business partners and other interested parties, they expressed interest in using it. An Open Source initiative was the logical way to make this happen

• By making it available to the world, we’re able to leverage input from people way smarter than we are and continuously make OpenEAI better than it is today

• Negotiated an agreement with University of Illinois that led to the intellectual property being gifted to the OpenEAI Software Foundation. This provides the structure to maintain and support the body of work and makes it possible to grow these concepts and technologies even more as time goes by and more people use them

How OpenEAI came to be

Benefits of OpenEAI1. Methodology

• Provides an analysis template and analysis process for analyzing and documenting the requirements of integrations, defining enterprise data objects, and specifying enterprise messages without requiring or referencing specific products

• The analysis process ties directly into the implementation process; in other words, the XML and other artifacts produced by following the methodology are actually used to generate and write code that implements integrations and documents their finished state.

NOTE: See the OpenEAI Methodology Document


2. Protocol• Provides a detailed structure for messages in XML format• Defines the message actions that can be performed on

enterprise data objects through messaging• Prescribes general behavior that applications must adhere

to for each message action in order to build reliable integrations and maintain enterprise data integrity

• Provides the format for specifying and talking about enterprise data objects, which are contained within the messages

NOTE: See the OpenEAI Protocol Document

Benefits of OpenEAI


3. Foundational APIs• Provides the set of tools that can be used to implement

defined integrations consistently and reliably

• Not required, but makes much of what has to be implemented much easier

• Key foundation components:

- Gateway pattern- Application foundation- Message objects- JMS foundation objects

Benefits of OpenEAI

NOTE: See the API Introduction and Implementation Strategies documents
