The Model Manager API supports the same version control functionality for items that is available using the Model Manager tools in the COMSOL Desktop. By combining options on parameter objects, it is even possible to perform advanced operations that are not easily done via the COMSOL Desktop — see Advanced Database Operations Using Parameter Objects. This includes, for example, importing files on the file system as new versions of existing items, importing item versions from another database, or updating an item from a version of another, possibly unrelated, item.
