3. User Interface Allow user to select a scenario “I want to…” Allow user to select data (including browse?) from grid data sources up to a given maximum Allow user to send comments or request advice/support Provide status: successful completion/un-successful completion/completion pending Authenticate user (id/password) Provide access to web pages of scenario documentation Allow user to delete data and delete result products from workspace Generate metrics: number of scenarios executed, execution time (TBD) Command line functions (documented in operator’s guide) Stop execution of user scenarios Review logfiles Read comments received from users Open/close user accounts Manage user resource allocations (user workspace storage allocations, etc.) Add new scenarios, or delete/modify existing scenarios (and add/delete/modify associated workflow parser) Production Control Parses user scenario into Grid workflow Generates fault or completion notification Generates metrics: start/stop time of workflow processes (TBD)

4. Workspace/Product Distribution Stages products for ftp Notifies user when products are available by email url Notifies user when disk allocation is exceeded Generates metrics: user demand, time/date of archive and pickup/deletion, used/free storage (TBD) Metrics/Logfile Chronological logfile Logfile of errors/faults
