METAFOR Objectives
Create a standard metadata Common Information Model (CIM) to describe climate data and the models and experiments that produced those data
• Allows essential data, model and experiment distinctions to be understood
• Builds on existing metadata standards used internationally in climate (CF, CDML, CSML, Curator, NMM, FLUME, ISO etc.)
• Uses existing format and framework (XML, RDF, etc.)

METAFOR Objectives
Develop, deploy, and evaluate a prototype infrastructure that will allow key data and models to be discovered and compared between distributed digital repositories
• single sign-on services to populate and manipulate, the CIM metadata
• services exploit NDG CSML to provide a common Geographic Markup Language interface to climate data
• centralized CIM content harvested from individual repositories using OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting).

METAFOR standards definition
International Emerging Community
Climate Modellinggridspec - model discretisationSensor ML - observationsNMM - model descriptionCERA2 - data management
DataCF for netcdf
Metafor will coordinate - filling of metadata gaps- mapping to different standards- aggregating the metadata- creating new standards (if necessary)

Identified Metadata Gaps
Existing metadata models in Earth system modeling provide description of model output. This description is complete with respect to browse, search, identify and use Earth system model results.
Identified gaps in existing metadata models for Earth system modelling are: Provennance information and Structured, searchable description of numerical models

Method of CV Developement in METAFOR
Application use case: CMIP5 / IPCC AR5 climate projections from Earth system
models Methods of CV development for the CIM software classes
Prototyping with selected Earth system model developing scientists (interviews)
Structuring with METAFOR procject Presentation and discussion within wider Earth system
modelling community Revised version is taken for the application use case Experience from application use will improve the CIM CV
implementation (next iteration loop) Requirement: community agreement is needed for acceptance Missing: formalised process to expand CIM CV lists is yet not in
place.
