Use case details

Create a new data package from existing database

There are existing data that are to be converted to packages.

• ws new PACKAGE-NAME (create workspace for a new package)
• cp data-files PACKAGE-NAME/output (copy data into workspace)
• cd PACKAGE-NAME
• ws pack --to REPOSITORY (create package from workspace)

Derive a new data package from existing data packages by computation

• ws new PACKAGE-NAME (create workspace for a new package)
• cd PACKAGE-NAME
• ws mount PACKAGE1 NAME1 (make data from PACKAGE1 [version] available at input/NAME1)
• ...
• ws mount PACKAGEn NAMEn (make data from PACKAGEn [version] available at input/NAMEn)
• create some program under the current directory (e.g. python or STATA scripts) that uses data from input and produces some data under output
• run the program
• ws pack --to REPOSITORY (create package from workspace)

Update a data package for new input data (create a new version)

• ws develop PACKAGE (create workspace )
• ws mount NEW-INPUT-PACKAGE NEW-INPUT-NAME (make data from NEW-INPUT-PACKAGE available at input/NEW-INPUT-NAME)
• modify code
• run code
• ws pack
