1. Going from Node to Flow Presented by Guy Outred

2. Introducing… Sponsored by Mentoring States and ECOS Based on input from States of varying geography, technology and Network maturity

3. Introducing… The intended audience for this document includes:  Partners who are yet to implement a Node  Partners who have implemented a Node, but are interested in alternative approaches  Partners looking to advance their Node implementation

4. Got Node? Need Exchanges?

5. Definition ‘Exchange’: the sharing of a specific type of data between two or more Partners; for example, sharing of water quality data. This is often also referred to as a ‘flow’.

34. Trading Partner Agreement Unilateral Between partners Use example if available Use TPA Guidelines

35. Exchange Reuse? Exchange = –Data transformation + –XML formulation + –Data services Some commonality across Partners Some recycling is occurring
