> Project: OASIS Energy Interoperation TC
> Issue Type: Improvement
> Components: schema
> Affects Versions: wd33
> Environment: Ed Cazalet

> Fix For: wd33

>
> In theory the potential multiplicity in Transactions is unlimited:
> One can contemplate
> 1 Party to 1 Party Transactions,
> n Party to 1 Party Transactions, and
> n Party to m Party Transactions.
> Additionally, any transaction can be for 1 interval or multiple intervals, and any Transaction can be for 1 EMIX product or many.
> Tenders have the multiplicity of Transactions plus additional potential multiplicity such as:
> For an n Party to m Party Tender are one or more Transactions for a subset of the Party and CounterParties allowed or must all n to m Tenders accepted as a single Transaction?
> And is the EMIX quantity for each Tender Integral Only or not ( all of the tendered quantity must be transacted or none)?
> In practice most tenders and transactions are bilateral (1 Party to 1 Party) for a single product. This is because of complex negotiation and default issues in complex transactions. And where complex m to n party transactions are desired, an exchange or clearing house is often the counter party to all of the Parties.
> Market matching methods are out of scope for EI. It would seem we have two choices for Transaction and Tender multiplicity in EI.
> 1. Allow unlimited multiplicity and expect implementers to restrict the multiplicity. Either restriction is by conformance rules or by using as yet undeveloped restrictions on multiplicity communicated in the Market Context.
> 2. Allow only 1 party to 1 party transactions and tenders for 1 EMIX Product on sequences of one or more intervals wherein the quantity in each interval is variable or integral only.
