• When collaborating, it is important to manage changes in the models. For example:– To create or edit a submodel

• E.g. Habitat suitability is replaced with another method of computing habitat values.

– To submit a “rough copy” of a model to the repository for review by collaborators at another institution.

– To keep track of data needed from other submodels.• Can submit a “data request” to all model developers

– To keep track of influences/data-flow between submodels.– To revise documentation.– To track revisions by author, time, date, revision number.– Possibly the best feature: Nothing is ever “gone

forever” , since you can always recover the last version.
