The objective of this project is to develop a data sharing middleware that is able to handle multiple distributed data sources and dynamically changing items, and to assist in real-time INFOrmation Dissemination (INFOD) across multiple agencies for homeland security purposes. The ultimate goal of the INFOD model is to support the timely delivery of valuable information. This page details on the INFOD development work done at the University of Tennessee, Knoxville and Oak Ridge National Laboratory.


INFOD is a product of the INFOD working group part of the Open Grid Forum(OGF), which involves a group of people from industry, research laboratories and academia. The group website can be found here[1].

For information on INFOD, the specification document can be found here [2].

The figure below details on the setup. The block to the right represents the INFOD registry service and the block to the left illustrates different levels of support for client side applications. Each of them is described in detail below.


For information on accessing a current version of the INFOD system, follow the link below.


INFOD Registry Setup

Installing Oracle Database 10g

  Download Oracle for Windows/Linux from here [3]
  For installation in Windows environment  
   * Install Microsoft Loopback Adaptor before installing the database.
   * Go offline and then install Oracle database.

OC4J - Oracle Application Server

 This is used for hosting the Registry web services.
 You can download OC4J from here [4]

Oracle JDeveloper

 This is a free IDE providing application development support.
 The current implementation uses it for deploying PL/SQL based web services to OC4J.
 JDeveloper can be download from here [5]

Registry Setup Steps

Client Utility tools

Instructions for installing infodweb, the web client for INFOD.

Install Apache tomcat [6] (tested on version 5.5.20)

Install PostgreSQL [7] (tested on version 8.3.3)

Start the database and initialize it (your paths may be different depending on where you installed PostgreSQL)

Start the database
(if it is already running as a daemon, skip this step)
/usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data >logfile 2>&1 &
Create a database instance
/usr/local/pgsql/bin/createdb infodweb

Initialize the database The setup file, db/setup.sql, is in the infodweb install directory

/usr/local/pgsql/bin/psql -f db/setup.sql infodweb

To deploy infodweb, you should have ant installed and a java sdk. You will most likely need to be root when deploying infodweb. To build infod, run

ant dist

or to deploy

ant deploy

Configuration options

The options marked + must be set for infodweb to work correctly

The options marked - may be changed if needed

The options marked * should be changed only if you know what you are doing

Options in build.xml

- The location of the tomcat installation directory
default: /usr/share/tomcat5
- The name of the tomcat webapp
default: INFOD

Options in java_source/gov/ornl/infodweb/Globals.java

+ Client address, the url of the tomcat installation
eg http://xxx.xxx.xxx.xxx:8080/infod/
* Client response url, the url that accepts incoming messages
eg client_address + Notify?userid=
+ Server address, the url of the INFOD server
eg http://xxx.xxx.xxx.xxx:8888/
+ Server url, the full path of the INFOD web service
eg server_address + RegistryWebService-INFODv1-context-root/WebServiceSoapHttpPort
* Type url, the namespace for the soap envelope
eg http://www.ggf.org/INFOD/
+ DB name, the name of the postgre database you want to use
eg infodweb
+ DB username, the username to use when connecting to the database
+ DB password, the password for your username

User Guide To login, go to login.html (relative to the url and webapp name from your configuration). This page will allow you to create a new user, or login as an existing user. After logging in, you will be directed to admin.html The admin page will allow you to interact with an INFOD registry via web forms. The page consists of a list of links, and record notification box. The notification box is updated with messages sent to INFOD entities created by the logged in user. To create an entity in the registry, click on the appropriately labelled item in the list on the admin page. The web form for each entity will include entry options for the values required by the INFOD specification. entity entry references are required for changing or dropping existing entity. For consumer, publisher, or subscriber entries, a file dialog allows uploading of code to be run to process messages received.

Code Format The infodweb interface is defined as a java interface with methods: The code must be a valid jar file. The class file that implements the infodweb interface must be called PublisherInterface.

install(Object x)
remove(Object x)
notifyMessage(Object msg)
run() (for publisher's only)

A First Responder Use Case Scenario

This example scenario is aimed at demonstrating the functioning of the INFOD model. The use case is a simple model illustrating an event and the communication between the first responders. The use case does not represent the real world and is solely aimed at illustrating the services provided with the help of the INFOD registry. A more realistic and real-world model is being developed in collaboration with first responders at ORNL and Univ. of Tennessee.

The use case is detailed here First Responder Use Case
