This page is devoted to describing the SimDB data model (SimDB/DM from now on). It is meant to reflect the proposal and incorporate conclusions from the discussions page.

Current model

As described here all development can be followed on Volute. Particularly relevant for the discussion on this page is the data model in uml/SimDB_DM.xml. The previous versions as well as later working versions can be found in the history of this file, as well as its direct predecessor version r902.

I propose that for the rest of the discussion we limit ourselves to the model in the specification subdirectory.

In this page we gather material to support the model.

Protocols

For discussion purposes it will be good to have a list of real protocols, i.e. simulation and post-processing codes and algorithms.

Examples of protocols:

Simulators:

• Gadget (http://www.mpa-garching.mpg.de/gadget/)
• Enzo ...
• Flash ...
• Nemo ...
• Ramses ...
• L-Galaxies (MPA semi-analytical (SAM) galaxy formation code)
• GalForm (Durham SAM code)
• GalICS (Horizon SAM)
• ...

Pure post-processors: cluster finders

• FOF cluster finders (various implementations)
• SUBFIND cluster finder (Springel etal 2001,
