Protobuf Tree Diffing for Multi-Contributor Content Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Content management systems lack robust change management, leading to errors, inconsistencies, and difficulties in effectively tracking and managing changes made by multiple contributors.
Innovation Solution
A differential management system that leverages structured data in the form of protocol buffer (protobuf) objects, converting them into tree data structures and using tree diffing algorithms to identify and track changes (deltas) between different instances of content, allowing for accurate change management and error resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If content management systems allow multiple contributors to make changes, then productivity and collaboration are improved, but errors and inconsistencies increase
Solution Approach 1:
The system implements feedback mechanisms by continuously monitoring content changes and automatically detecting conflicts between concurrent edits. The conflict detection system provides real-time feedback to contributors about potential inconsistencies, allowing them to resolve issues before they propagate through the content management system.
Solution Approach 2:
The patent introduces an intermediary conflict detection and resolution system that mediates between multiple contributors. This intermediary layer analyzes content changes, identifies conflicts, and manages resolution processes, allowing multiple users to collaborate while maintaining content consistency through automated mediation.
2Reliability
If change tracking is implemented to improve reliability, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The content is segmented into discrete objects with unique identifiers, allowing the system to track changes at the object level rather than requiring complex full-content comparison. This segmentation enables precise change tracking while reducing system complexity by breaking down the monitoring task into manageable, independent units.
Solution Approach 2:
The system uses parameter-based tracking by monitoring specific attributes of content objects (such as object IDs, version numbers, and change timestamps) rather than analyzing entire content structures. This parameter-focused approach improves tracking accuracy while minimizing the computational complexity required for change detection.
3Loss of information
If detailed change tracking is implemented, then loss of information is reduced, but loss of time increases
Solution Approach 1:
The system extracts only the essential change information (object identifiers, change types, and version data) from content modifications, storing and tracking only these critical elements rather than complete content copies. This extraction approach maintains information completeness for conflict resolution while significantly reducing the time required to process and store change data.
Solution Approach 2:
The patent implements partial tracking by monitoring only the specific parameters necessary for conflict detection (such as object IDs and version numbers) rather than performing exhaustive analysis of all content attributes. This partial action approach provides sufficient information for reliable change tracking while minimizing processing time.
Data Source
AI summary
A method for differential management includes obtaining a first instance and a second instance of content of a content management system, the first instance including a first plurality of objects of the content, and the second instance including a second plurality of objects of the content. The method includes determining a first tree data structure representing the first plurality of objects at the first instance and a second tree data structure representing the second plurality of objects at the second instance. The method includes identifying, based on a comparison of the first tree data structure and the second tree data structure, a set of deltas. The method includes transmitting, to a client device, the set of deltas that, when received by the client device, cause the client device to display the set of deltas via a user-interface of the client device.
