Fine-Grained Version History for Collaborative Documents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Collaborative document platforms provide only coarse-grained version histories, failing to detail each edit made to electronic documents, leading to increased editing time, resource consumption, and memory inefficiency, especially with large documents.
Innovation Solution
Implement a system that tracks each edit by type, coordinates, timestamp, and user, storing these mappings in an edit data structure, allowing users to access fine-grained version histories through a GUI element that renders previous document states based on user selections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If coarse-grained version histories are provided, then memory consumption is reduced, but editing detail and precision are lost
Solution Approach 1:
The patent segments the document version history into fine-grained edit units, where each edit is tracked individually with its own metadata (timestamp, user, type, coordinates). This segmentation allows the system to store only the necessary details of each edit rather than entire document versions, reducing memory consumption while preserving edit information.
Solution Approach 2:
The patent adds a temporal dimension to the edit history by recording timestamps and creating a timeline-based navigation interface. Users can traverse through edits chronologically using GUI elements that represent different time points, allowing detailed review without storing all intermediate document states in memory.
2Measurement precision
If fine-grained edit tracking is implemented, then editing precision is improved, but system complexity increases
Solution Approach 1:
The patent creates a simplified copy or representation of the edit history in the GUI rather than displaying raw data. The edit history is presented as a navigable timeline with visual indicators, transforming complex metadata into an intuitive interface that users can interact with easily.
Solution Approach 2:
The patent introduces an intermediary layer between the complex edit tracking system and the user. The GUI elements act as mediators that translate fine-grained edit data into visual representations, allowing users to access detailed information without being overwhelmed by the underlying system complexity.
3Loss of information
If detailed edit histories are stored, then information completeness is improved, but resource consumption increases
Solution Approach 1:
The patent extracts only the essential metadata from each edit operation (timestamp, user identifier, edit type, coordinates) and stores this extracted information in a structured format. By taking out only the necessary information rather than storing complete document states, the system achieves information completeness for tracking purposes while minimizing resource consumption.
Solution Approach 2:
The patent changes the parameters of what is stored from entire document versions to specific edit parameters (timestamp, user, type, coordinates). This parameter transformation allows the system to maintain complete edit information while dramatically reducing the amount of data that needs to be stored and processed, thereby lowering resource consumption.
Data Source
AI summary
A first version of an electronic document is provided via a first region of a graphical user interface (GUI) for presentation to a first user of a collaborative document platform. A second region of the GUI includes an edit history GUI element that enables one or more users to access each edit made to the electronic document. A user selection of a portion of the edit history GUI element is detected. The user-selected portion of the edit history GUI element corresponds to edits made to the electronic document by a second user. A determination is made of a state of the electronic document following the edits made by the second user. The first region of the GUI is updated to include a rendering of a second version of the electronic document. The second version is rendered in view of the determined document state.
