The Common Metadata for Climate Modelling Digital Repositories, or METAFOR project, is creating a Common Information Model

 (CIM) for climate data and the models that produce it.

The CIM aims to describe climate data and the models that produce it in a standard way, and to address the fragmentation and gaps in availability of metadata (data describing data) as well as duplication of information collection and problems of identifying, accessing or using climate data that are currently found in existing repositories. A further aim of the METAFOR project is to ensure the wide adoption of the CIM.

METAFOR is optimizing the way climate data infrastructures are used to store knowledge, thereby adding value to primary research data and information, and providing an essential asset for the numerous stakeholders actively engaged in climate change issues (policy, research, impacts, mitigation, private sector).

METAFOR has created tools for practical use of the CIM, e.g., the CMIP5
Coupled model intercomparison project
In climatology, the Coupled Model Intercomparison Project is the analog of AMIP for global coupled ocean-atmosphere general circulation models. CMIP began in 1995 under the auspices of the Working Group on Coupled Modeling , which is in turn under auspices of CLIVAR and the Joint Scientific...

The CMIP5 questionnaire is an ambitious metadata collection tool and will help scientists to provide the most comprehensive metadata of any climate model inter-comparison project. It aims to collect enough detail to allow users to easily:
  • browse the archive & find desired datasets
  • easily differentiate between the “genealogy” (related models & experiments) of datasets


The questionnaire also allows users to enter descriptions of components which are not already specified by the questionnaire controlled vocabulary. It produces XML output complies with the Metafor Common Information Model (CIM), allowing tools and services developed using the CIM to be applied to the questionnaire outputs.
