Here I present technical details on the software package PMR2, which is the software running the CellML and Physiome Project model repositories. In particular, the use of mercurial repositories to define workspaces for collaborative model development, creating modular hierarchies of embedded workspaces, and defining exposures as a means to provide permanent links to specific revisions of model workspaces. I also briefly mention the use of OpenCMISS to link CellML models into large scale, spatially distributed field modeling and simulation. |
