1. E-Tariff Technical Volunteers Status Update
July 27, 2007 1

2. June 4th Action Item
Call to Action: for volunteers to create a “Strawman” XML Schema based on the metadata elements identified under Option A by FERC
Purpose: To establish a starting point from which technical design discussions could begin
Expected Deliverable: An XML Schema document to serve as a strawman “starting point” for technical discussions
No long term solution is expected from this action item – only a strawman starting point! 2

3. Progress Report
Group currently has representatives from Gas Pipelines, Electric Utilities, ISO/RTO’s and Software Vendors. Representation from the Oil Industry is desirable; Will solicit participation from AOPL.
Two XML schema proposals have been submitted for consideration as the e-tariff strawman XML schema:
Pipeline Segment Proposal
FERC Proposal
The two proposals are very similar but different enough to warrant a technical discussion
Kick-off conference call was held on July 19
Review of 6/4 Action Item and establish common understanding of deliverable/scope
Recommendation to create a formal NAESB WGQ / WEQ eTariff Technical Subcommittee to complete development of the corresponding eTariff technical specifications to be included in the overall eTariff package
Discussed next steps 3

4. Next Steps
Tech Team to hold a face to face meeting in Washington 3rd week of August (FERC hosting)

Presentation of each strawman proposal by submitter
