The Entity Choreos allow you to access information on the people and organizations for which information is available through LittleSis.
To use the Choreos in this bundle, you'll need to sign up with LittleSis.org and obtain an API Key. More information on obtaining an API Key can be found here. Detailed information about the Entity methods available through LittleSis can be found here.
It may be useful to familiarize yourself with the data structure of the LittleSis API, which is described here. The main types of records are Entities, and Relationships, which track a known connection between two Entities. Other types of records are Lists (such as "Forbes 400" or "Federal Bailout Recipients") that are stored separately from Relationships.
Entities are each assigned an ID and an Entity record may contain a number of Aliases to track the fact that a single person or organization may go by many different names. There are several Types of Entities, which can be looked up with the EntityTypes Choreo. For each Type, the Entity record may contain additional fields, e.g. the "PublicCompany" type returns a "ticker" field.
