Nexus Metadata

Nexus Delta entities fall in two categories:

• Global: Organizations, Realms, Permissions, ACLs
• Project scoped: Projects, Resources, Schemas, Resolvers, Views, Storages, Files

Upon creation of these entities, Nexus Delta will create metadata fields which are described below.

• _self: unique address of the entity across Nexus Delta
  • Nexus Delta follows the HATEOAS architecture, which is reflected in the _self address being discoverable in Nexus Delta’s different responses. Example: from a resources listing operation, the _self endpoints listed can be used to fetch the underlying resources

Auditing

The following metadata can help to audit an entity.

• _rev: the revision number of the entity
• _deprecated: boolean indicating whether or not the entity is deprecated
• _createdAt: datetime at which the entity was first created
• _createdBy: the user that first created the entity
• _updatedAt: datetime at which the entity was last updated
• _updatedBy: the user that last updated the entity
