Unless otherwise noted, all entries at the top level are constructed and provided by the server and can not be modified by clients.

• base (URL): Base URL for any relative HREF values in the data. When items are returned in a list, base will typically not be included with each entry.
• id (Lightroom-style UUID): Unique Lightroom identifier of this asset. It is usually generated by client on creation but may be generated by the server in some circumstances.
• created (ISO 8601 date): Date when asset was first uploaded to the server.
• updated (ISO 8601 date): Date when asset was most recently revised on the server.
• type (string): Always the same value for a type.
• subtype (string): A different set of legal values is defined for each type. Provided by the client on creation. A subtype is always required for types that support it.
• payload (optional, table): Metadata about the object provided by the client.
  • Values supported within the payload generally differ for each document type.
  • If the payload is completely empty, which is allowed for some types, then it will be omitted.
  • userCreated (ISO 8601 date): Date and time when the user created this document on the client side.
  • userUpdated (ISO 8601 date): Date and time when the user last updated this document's payload (or other user modifiable data). This should be set at initial creation and updated by a client each time a user makes a change to data within the payload hash. The userUpdated time should not be updated by automated processes (e.g. reverse geocode, etc.).
• links (table): Links to related data.
  • Each entry is a table containing an href entry with the actual link.
  • All types include the self link.
  • Each type may have other links supported.
