Facts and Figures METAFOR

Common Metadata for Climate Modelling Digital Repositories EU FP7 e-infrastructures project 11 partners Total budget of 2.2M€ Starting in March 2008, duration 3 years The principle aim of METAFOR is to develop a Common Information Model (CIM) to describe the numerical models that produce this data.

Vision of

CIM Common Information Model based on current, emerging and new metadata standards Tools that populate, create, manipulate, convert and climate models and climate model data to be inter comparable and sharable. (CIM - Common or Climate Information Model ?)

is not just about the metadata but also about

-

being able to gather or create the metadata

-

building diverse repositories

-

enabling and designing tools to exploit the metadata Common Metadata for Climate Modelling Digital Repositories

Common Metadata for Climate Modelling Digital Repositories

The information modelling of the climate modelling process requires GO-ESSP Seattle 2008 • a degree of commonality • with community agreement to achieve this • governance mechanisms to develop and maintain this • extensions for local use or translations to other systems common community The ‘fried egg’ implementation of the information model

Activity Software Data

With a clear understanding of package descriptions

An Activity is an abstract package of project, ensemble, campaign, investigation.

Data in all its guises and usage within the climate modelling process.

Software which includes all parts of the activity that takes place on a computer.

Grid ie gridspec Quality measures that could be applied to activities, software or data.

Re-usable entities for example responsible person, defined within ISO.

UML class diagram + dictionary Re-usable entities and the aim to achieve

• a separation of concerns • encouragement of interested parties to participate in discussion • ensuring a degree of governance • a mechanism for separate development

Why is separate development necessary?

for AR5 • CIM based data portals design and implementation • CIM to encompass AR5 metadata requirements  Access to CIM tools and services • CIM verification  part of AR5 quality control • CIM tools for ingestion  tools made available to modellers • CIM exploitation tools

Issues for discussion meta for

timelines are tight, it is a 3 year project that wants to provide a community CIM and tools that survive and evolve beyond this project governance is slow and difficult there is the challenge of achieving generic community acceptance
