by e-mail (e.g., zip files) with little regard for formal versioning, relying instead on active communication and straightforward date-based or as-needed code versioning. Project management included defining and testing program components built at Vanderbilt and at the two partner institutions. Extracting the codebase for installation at partner institutions required programming effort at Vanderbilt but did not require extensive documentation given the frequency of communication among developers and a similar technical infrastructure in each destination environment. Local context access control was abstracted and enabled using lightweight directory access protocol (LDAP) system methods.
