All license fields and interpretation

• Id: 'lowercasealphanumeric': Unique identifier for the license
• Secret: 'lowercasealphanumeric': Secret key that permits remote license retrieval.
• Kind: [id | domain | subscription ]: id means the license is a placeholder for a remote domain.
• IsPublic: true: License fields (excluding Secret) are displayed on a public web-service endpoint
• Owner: Company or Name: Name of the licensee (required)
• Domain: lowercase.com: Used as the license identifier if the Id field is absent. One of the two is required.
• Domains: a.com b.com c.com and Domain: d.com: Serves to restrict usage of the license to requests with the given hostname(s).
• Features: FeatureA VersionXFeatureB: Space-delimited feature codes. If these serve to activate all features that are in use, then the license is considered valid.
• Valid: false: The license has been revoked
• NetworkGraceMinutes: integer: For a placeholder license that has never been fetched/cached to disk: how many minutes to delay enforcement while attempting to connect to the internet.
• Expires: iso8601 date: When the license becomes invalid
• ImageflowExpires: iso8601 date: When the license becomes invalid for Imageflow
• Issued: iso8601 date: When the license becomes valid
• SubscriptionExpirationDate: iso8601 date: Product builds after this date are not valid with this license
• `LicenseServers: https://s3-us-west-2.amazonaws.com/licenses.imazen.net/ https://licenses-redirect.imazen.net/ https://licenses.imazen.net/ https://licenses2.imazen.net/
• MustBeFetched: true: Don't validate the license unless it comes from a license server (or its cache).
