OASIS Energy Interoperation TC

My comments on the large changes in WD27 did not seem to come through – only my header notes. Here is the complete submitter notes:

Most comments from public review have been dealt with, over-arching comments on page 1 will be reviewed after specific comments throughout document finalized.

Most of the UML has been updated with minor changes, chiefly from careful alignment of different sections, such as the new preeminence of the TenderBase, creating commonality between Tenders, Quotes, Transactions, etc. We welcome comments on all UML before Section 13.

The most changes and largely completed new work is in sections 9-12, Negotiations, Subscriptions, and the subscription-based Tickers and information on specific Instruments from the Market. The Editor recommends review of these sections.

The biggest changes of WD27 is the move from Venue Type to Market Mechanism Typology (MMT). MMT is based primarily on based primarily on the Federation of European Securities Exchanges (FESE) taxonomy created to permit comparison and analysis of transactions across multiple exchanges and venues. MMT enables a Market Segment to self-describe so that an automated participant can adopt automatically to more than simple order-book markets, but to load-curve discovery and negotiation useful to industrial concerns, to transitional semi-regulated day-ahead pricing markets, and to real-time pricing markets. Look to the new Appendix B (still in flight) for a discussion of trading in divers markets.

Section 13 describes how a Segment describes itself to a potential participant. It is very much in flight, with duplicate and not fully normalized message payloads. For full understanding, I recommend considering it alongside the non-normative appendix B. We are not asking for a review of 13 at this time, but include it so you see our intent. Please let the TC know if you see something you want included.
