Using Subversion and TortoiseSVN for Windows by Galen Wilkerson Gund Institute for Ecological Economics University of Vermont

Lesson Plan Go over installation of Subversion and Simile (windows/mac) On your own: Go through the Simile tutorials On your own: Go through our presentations on Subversion – TortoiseSVN (Windows) or svnX (Mac) – remainder of this presentation We will be available another time on Wimba and by /phone to answer questions about the tutorials

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.
