Link
Links define the type of relation/connection that can exist between different Units
Persistence
When you create a Relation link their information are stored inside our Database, according to the defined project, inside
the arke_link table.
We have the type column that stores the link_id, the parent_id/child_id that stores the unit that we want to link to
and metadata that define additional link information.

RESTful Endpoints
When you create a Link a set of default API are generated to manage it, the API could be authenticated and could have restricted permissions, additional params are ready-to-use like sorting, filtering and more. Discover them in the dedicated RESTful API section.
