A 'Derived' relationship can be applied from one package to another.

e.g. sussex-demography is derived from census-2001

'Derived' relationship is:

• directional
• many:many
• stateful

'derived' table columns:

• id (primary key)
• source_package (foreign key)
• result_package (foreign key)
• description (markdown text)

Further tickets:

• WUI - package view - shows 'derives from package x' and 'derived package y' with UML-like diagram of x -> this package -> y
• WUI - package edit form - new option to say it 'derives from' or 'has derivation' and you select the appropriate
• REST if - expose reading and writing this property

A 'dependency' relationship can be applied from one package to another. It implies that a package requires the download or existence of another package which it 'depends on'. (Analogous to software package dependencies.)

e.g. london-traffic-visualisation depends on road-map

'Dependency' relationship is:

• directional
• many:many
• stateful

'dependency' table columns:

• id (primary key)
• dependent (foreign key)
• dependency (foreign key)

Further tickets:

• WUI - package view - have list of dependencies (do not need to list packages which depend on this one)
• WUI - package edit form - new option to say 'depends on' (no need for 'has dependent package')
• REST api - expose reading and writing 'depends on' property.
