15-day Public Review for OASIS Energy Market Information Exchange (EMIX) v1.0

The OASIS Energy Market Information Exchange (eMIX) TC members have produced an updated Committee Specification Draft (CSD) and submitted this specification for 15-day public review:

Energy Market Information Exchange (EMIX) Version 1.0
Committee Specification Draft 02 / Public Review Draft 02
28 April 2011

Specification Overview:

This specification is one of three related OASIS technical works in progress:

(a) Web Services Calendar (WS-Calendar Technical Committee page is is the common XML vocabulary for expressing schedules. EMIX uses this vocabulary to express energy schedules and prices; implementers and other standards are also using WS-Calendar. WS-Calendar has just completed its second Public Review.

(b) Energy Market Information Exchange (EMIX Technical Committee page is is the TC that has approved this public review. EMIX is the common XML vocabulary for expressing market information including tenders, market transactions, prices and product definitions for implementers and other standards. EMIX uses the WS-Calendar vocabulary to express schedule information, and the EMIX vocabulary is used by Energy Interoperation and other standards and implementations.

(c) Energy Interoperation (Energy Interoperation Technical Committee page is is the common XML vocabulary for expressing curtailment events, price communication, as well as Web services definitions for interactions using the information payloads. The Energy Interoperation TC is planning its second Public Review in May 2011.

For a graphical view of the relationships, see on the NIST Smart Grid collaborative site.

This second review of the specification contains substantial editorial changes correcting and clarifying issues raised during its first review period. No changes to the functionality described in the specification have been made as part of these changes.

Please refer to line numbers in the PDF rendition of the specification when providing comments.

The OASIS Energy Market Information Exchange (eMIX) TC [1] was chartered to define standards for exchanging energy characteristics, availability, and schedules to support the free and effective exchange of information. Better communication of actionable energy prices will help enable and expand efficient markets that satisfy the growing demand for lower-carbon, lower-energy buildings, net zero-energy systems, and supply-demand integration that take advantage of dynamic pricing.

Public Review Period:

The public review starts 12 May 2011 and ends 27 May 2011. The specification was previously submitted for a 30-day public review on 17 November 2010 [2]. This 15-day review is limited in scope to changes made from the previous review of 17 November 2010.

Changes are highlighted in the diff-marked PDF and editable source files [3].

This is an open invitation to comment. OASIS solicits feedback from potential users, developers and others, whether OASIS members or not, for the sake of improving the interoperability and quality of its technical work.
