Groups

Introduction

The Group API is a method of getting access to descriptions of sets of people and/or subgroups, such as families, organizations, companies, departments or any other identifiable set of actors. The Group model is of average complexity with many familiar properties and patterns, plus a few more specific fields. This results in an average complexity API, which is very similar to the Person API, that can result in reasonably long JSON responses if all of the fields have values.

For more information about the usage of Group data, please see the Group model description.

Property Definitions

Dereferencing an entity via the Group endpoint would result in a JSON-LD document containing a single JSON object with the following properties.
