Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Most content management systems are optimized for specific usage models and are not flexible enough to accommodate changes in access permissions, especially in cloud-based environments where synchronization and collaboration are critical.
Innovation Solution
The implementation of a robust and flexible access control list mechanism that efficiently checks access at read time, allows for customizable access permissions, and maintains system-wide ordering of events to determine historical data states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a content management system is optimized for a particular usage model, then it achieves high performance for that specific usage, but it becomes poorly suited for other usage mechanisms and lacks flexibility
Solution Approach 1:
The patent implements a universal event-driven architecture that can handle multiple usage models through a single unified event stream processing mechanism. The system processes various types of events (object changes, access control changes, synchronization events) through a common data model and event handling framework, enabling the same system to efficiently serve different usage scenarios without requiring separate optimized instances.
Solution Approach 2:
The system employs dynamic event subscription and filtering mechanisms that allow the processing pipeline to adapt its behavior based on the specific usage model being accessed. Different clients can subscribe to different event types and receive customized event streams according to their needs, while the underlying system maintains a unified event source that efficiently handles all event types.
2Speed
If access control checks are performed at read time, then access management becomes efficient and quick, but the system must maintain system-wide ordering of events to determine historical data states
Solution Approach 1:
The system performs preliminary actions by maintaining a centralized event stream that records all changes to objects and access control lists in system-wide chronological order. This event stream serves as a pre-computed history that enables rapid access control checks at read time, as the system can simply query the event stream for relevant past events rather than performing complex real-time analysis.
Solution Approach 2:
The patent introduces an event stream as an intermediary data structure that mediates between write operations and read operations. The event stream captures all access control changes and object modifications in a standardized format, serving as an intermediate representation that simplifies both the complexity of maintaining system-wide state and the speed of performing access checks.
3Stability of the object's composition
If a content management system is deployed as a specific instance on enterprise level, then it achieves stability and control, but it is not suitable for modern cloud-based content management systems that require synchronization and collaboration
Solution Approach 1:
The patent segments the content management system into independent, loosely-coupled components: an event source that generates events, an event stream that transports events, and event processors that consume events. This segmentation allows the system to maintain stable core functionality while enabling flexible deployment scenarios including cloud-based multi-instance architectures where each instance can independently process events and synchronize state.
Solution Approach 2:
The event stream acts as a mediator that enables synchronization and collaboration between multiple cloud instances. By standardizing event formats and providing a universal event interface, the system allows different cloud instances to exchange state changes and coordinate their operations, maintaining stability through consistent event processing while adapting to distributed cloud environments.

AI summary
The disclosed technology addresses the need in the art for a content management system that can be highly flexible to the needs of its subjects. The present technology permits any object to be shared by providing a robust and flexible access control list mechanism. The present technology utilizes a data structure that is highly efficient that both minimizes the amount of information that needs to be written into any database, but also allows for fast reads and writes of information from authoritative tables that are a source of truth for the content management system, while allowing for maintenance of indexes containing more refined data that allow for efficient retrieval of certain information that would normally need to be calculated when it is needed.
