Agenda History of the project Why did we become involved TIDEN Overview

History of the project 2002 Grant n Prepare infrastructure 2003 Grant n Build Node 2004 Grant n Add data flows

Why did we become involved Each Program area had different process Foundation for future electronic reporting Lessons learned

TIDEN Vitals TIDEN is a J 2 EE application

TIDEN Overview TIDEN Top 4 Features n n TIDEN as a Framework User Management Domains Status

TIDEN as a Framework

The Problem: Change Specs/Protocols will change Local Web Service Methods will get added Flows will include cross programs areas Flows have unique (mapping, process, schedule, etc) and common requirements Multiple flows will be developed/maintained concurrently Flows need to be relatively independent from one another The only constant is change

TIDEN Framework: Overview Example Query Web Method Query(<token>, <request>, <row. ID>, <max. Rows>, <parameters>) Query Operations: 1. Query(<token>, get. Fac. By. ID, <row. ID>, <max. Rows>, <parameters>) 2. Query(<token>, get. Fac. By. Name, <row. ID>, <max. Rows>, <parameters>)

TIDEN Framework: Operations TIDEN framework provides a common workflow for operations of a handler Each operation has hooks at certain points for operation specific implementation to be “plugged” in

Adding a TIDEN Operation

Lessons Learned Understand the specs/protocols Understand the relationship between Web Methods Initially focus on Web Methods and relationships you know you need

User Management

The Problem: Managing Users Diverse types of users (people and machines) Each flow has users and policies Some users cross flow boundaries Some users cross state boundaries User vs Administrator users NAAS required integration

NAAS Potential solution to user management issues Pros n n n Already developed and free! Supports comprehensive authentication Supports sharing users across partner Nodes Works well for exchanges among Node partners Easy to get up and running on Network Provides Web Services for management Cons n n Limited scope (spec/protocol Web Service Methods) authorization granularity management capabilities (e. g. - GUI) control All Nodes must support NAAS tokens!

NAAS Interface

User Management Use NAAS Web Services to: n n n Manage NAAS Users and Policies Provide GUI Management Extend NAAS

TIDEN Interface: Summary

TIDEN Interface: New User

Lessons Learned Understand NAAS Features/Limitations Determine User Management interactions early on Keep It Simple Stupid (KISS) n No synchronization with NAAS server More NAAS Web Services are needed

Domains

The Problem: Delegation Program Areas have the business knowledge Program Areas are the end users Flows will cross Program Areas Flows should reuse existing logic when possible Solution should allow for flow independence

Domains Node Domain Air Domain Central Registry Domain Node Domain • Node Domain: Authenticate, Node. Ping, Get. Status, Get. Services • Other Domains: Submit, Query, Solicit, Notify, Download • Each Domain is assigned a Domain Admin • Domain Admins manage users and policies for their domain Not all Web Methods are shown in the diagram.

Lessons Learned Domains should be logical Need special “Node” Domain Admins can modify any TX Node User

What’s your Status?

The Problem: Status Node. Ping and Get. Services provide basic information only Web Services require a client able to call them and process results How do you provide quick and easy access to your Node’s status?

Lessons Learned Use Get. Services or not? How much information?

Parting Thoughts Determine goals for flow and user management n Centralized vs distributed Determine types of flows you need to support in near future Understand NAAS functionality and limitations Design for extension, not modification Share what you learn! The success of the network depends on you!
