10. PIMMS has separate interfaces for
Experiments and Requirements
So we can reuse requirements!
https://github.com/cedadev/pimms/ http://pimms.ceda.ac.uk

11. Experiments for the CASCADE
project
Cascade experiments were
mainly classified by
(1) location and (2) time period.
Using these distinctions, 4
experiments were devised for
Cascade; denoting the two
primary regions of study and
the two periods of study that
match well with observational
• Africa_July2006 data.
• Africa_Aug2006
• Indonesia_July2006
• Indonesia_Aug2006

16. PIMMS provides a structure and formalism
The information it collects is chosen by the users.
Users make the decisions about the level of detail they wish to capture.
PIMMS is an opportunity to achieve consistent documentation
research community, research groups and individual managing their own data.
PIMMS metadata is decoupled from data
This allows PIMMS to capture metadata at all stages in the workflow.
Information can persist even if data is discarded.

17. Where does PIMMS fit into
the workflow of running simulations?

18. Three Paradigms of
PIMMS Metadata Collection
Model Inter-comparison Projects
Where a standard set of questions is asked of all models
which perform a standard set of experiments
Disciplinary Metadata Collection
Where a standard set of questions is asked of all models
which perform experiments specified by users
Bespoke Metadata Creation
Where the users define questions about both models and
experiments
