  1. Functional specification:data exchange standards Pre-sessional consultations on registries 2 June 2003 Bonn, Germany Andrew Howard UNFCCC secretariat www.unfccc.int ahoward@unfccc.int

  2. Scope • Development stages • Introduce the functional specification • Map the specification against COP decisions • Implications for registry developers • Indicate necessary refinements in the specification

  3. Registry systems and data exchange National registry (of an Annex I Party) CDM registry (for Non-Annex I Parties) Sender/receiver Sender/receiver Communication via the data exchange standards Sender/receiver Communications hub Autochecks Transaction log

  4. The data exchange standards Transactions are enacted through data exchange Standards ensure sufficient harmonization • Data formats for data exchange • Sender/receiver units of registries and the transaction log • Behind-the-scenes to ensure accuracy and auditability

  5. Development mandated in decision 19.CP.7 Data exchange standardin decision 24/CP.8 COP 7 Functional specifications General design requirements COP 8 Technical specifications Requirements on what the standards are to mandate Current Detail on how they are to be implemented Dec 2003 Data exchange standards development stages

  6. Purpose of the functional specification To translate COP decisions into technical terms To guide the later technical specification of the standards This is done through identifying Key requirements that the standards are to mandate Mandatory constraints on how the requirements are fulfilled Acceptance criteria for non-mandatory aspects Written in technical terms for a technical audience Read in conjunction with the glossary!

  7. Structure of the document Introduction Outline of the purpose, scope and derivation documents Assumptions What is to hold true for the functional specification to be valid Data transfer format Functional and non-functional requirements Functional specification Registries Functional and non-functional requirements Transaction log Functional and non-functional requirements General constraints General boundaries that the standards must stay within Interfaces Defines the interfaces that must be supported by the standards

  8. Registries(functional requirements)

  9. Registries(non-functional requirements)
