Collaborative Authoring with Granular Content Locks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional collaborative editing methods often result in delays and conflicts due to serial access and merging of documents, making it difficult to manage who is editing which portions and resolving version control issues.
Innovation Solution
A collaborative authoring environment where multiple users can edit a document concurrently by generating content locks on data units, synchronizing metadata automatically, and synchronizing content updates only upon request, preventing editing conflicts and managing document changes efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users take turns accessing and editing a document serially with locking, then editing conflicts are avoided, but collaboration efficiency and productivity deteriorate due to waiting delays
Solution Approach 1:
The patent divides the document into multiple data units (sections, paragraphs, or individual elements) that can be independently locked and edited. This segmentation allows different users to work on different portions of the document simultaneously, eliminating the need for serial access while preventing conflicts through granular locking of specific data units.
2Productivity
If multiple users edit different copies of a document and merge them, then concurrent editing is enabled, but merge conflicts and management complexity increase
Solution Approach 1:
The patent introduces a server as an intermediary that maintains a master copy of the document and coordinates all editing operations. Users edit local copies that reference the master copy, and the server automatically synchronizes changes, resolves conflicts, and manages version control. This eliminates the need for manual merging while enabling concurrent editing.
3Reliability
If a user places a lock on the entire document, then editing conflicts are prevented, but other users cannot edit any portions of the document even if they want to work on different sections
Solution Approach 1:
The patent segments the document into multiple data units that can be independently locked. When a user locks a specific data unit, only that portion is protected from simultaneous editing, while other data units remain accessible to other users. This provides both conflict prevention and collaboration flexibility.
4Loss of information
If users manually track document versions and editing status, then version control is maintained, but time and effort are wasted on manual tracking
Solution Approach 1:
The patent implements automatic feedback mechanisms where the server continuously tracks document versions, locking status, and editing progress. Users receive real-time notifications about document state changes, and the system automatically updates version information. This eliminates manual tracking while maintaining accurate version control.
Data Source
AI summary
A collaborative authoring application provides an authoring environment in which two or more users can edit a document concurrently. Each user edits a copy of the document, sends updates to a master copy of the document, and receives updates from the master copy of the document. The authoring environment generally inhibits the users from providing conflicting editing instructions to the master copy of the document. For example, each user can generate a content lock about one or more data units within the document. The authoring environment may synchronize content locks automatically and content only at the request of the user.
