Object management system.

Description

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).

Architecture

Structure

• Metamodel module - loads object definitions, reflects metadata definitions on data schema.
• CRUD module - persistence api for actual object data.
• Security module - restricts data access based on role model.
• Client web interface with REST api - user interface.
