The system operates with definable objects. Every object consists of attributes set and statuses. Objects can be linked together. Status can apply restrictions on attributes. There is a security mechanism of roles, that restrict object, attribute manipulations and status changes.

The system operates with two schemas: metadata schema (contains object definitions and restrictions) and data schema (contains actual object data).
