Increasingly, the biological modelling community is looking for ways of handling complex and possibly dynamic structures in their models. On the one hand, the pathway-modelling groups (SBML and CellML) seek to move up levels of organisation, while on the other hand the "Virtual X" communities (where X is some organism or organ) need to represent the organisational structure within their object of study. To date, various approaches have been proposed, such as the SBML Level 3 'comp', 'spatial', 'array' and 'dyn' extension packages, and domain-specific elements in languages such as NeuroML, but there is no generic approach intended to be adopted by the various... |
