Collections (legacy)

A collection resource allows you to group a set of Thngs under some common grouping criteria. For example, a collection can be used to represent a production batch of some product, where the Thngs in the collection are the individual manufactured items from that batch. This can make it easier for Application Users to manage all the Thngs they created while using an application. This works by assigning a reference to the collection to each Thng, and listing the Thngs that reside in each collection. Collections can be added as children to other collections (such as a pallet within a container), and so on.

Collections have a similar data model to other resources in the Platform (a name and description, tags, and customFields etc.) and are created in a similar manner. Once a collection has been created, users can add or remove Thngs to or from that collection. See below for examples.

In addition to specifying a collection in an action, it is also possible to create an action through the collection itself using aliased actions.
