Activity Stream Customization via Protocol Buffers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for delivering activity streams in social networking and messaging tools are limited by their reliance on predefined formats, making it difficult to customize the presentation of activity information and related actions, requiring manual changes to templates, data formats, and JavaScript classes.
Innovation Solution
A system and method for per-client, per-type customizations in activity streams, utilizing an extraction pipeline that converts activity information into type-specific protocol buffers based on client and activity types, allowing for dynamic processing and rendering of activity information on client devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a predefined and fixed format is used for sending and presenting activity information, then system simplicity is maintained, but customization capability is limited
Solution Approach 1:
The system segments activity information into structured protocol buffers with distinct fields for activity type, client type, and presentation parameters. This segmentation enables selective customization of specific activity aspects while maintaining a standardized overall structure, resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The system uses parameter-based customization where protocol buffers contain configurable fields that define presentation characteristics. By changing parameters within the standardized buffer structure, the system achieves diverse customization capabilities without fundamentally altering the core data format, thus maintaining system simplicity while enhancing adaptability.
2Adaptability or versatility
If manual changes are made to presentation templates, data formats, and JavaScript classes for customization, then flexibility is achieved, but development time and complexity increase
Solution Approach 1:
The system performs preliminary action by pre-defining protocol buffer structures and activity type classifications. This advance preparation enables rapid customization through configuration rather than manual coding, significantly reducing development time while maintaining presentation flexibility.
Solution Approach 2:
The system uses template-based presentation where standardized protocol buffer formats serve as reusable copies. Once a presentation template is established for a particular activity type, it can be replicated and adapted for similar activities without recreating the entire presentation logic, thereby reducing development effort.
3Ease of manufacture
If a single codebase supports multiple client types, then code reuse is improved, but handling client-specific customizations becomes more complex
Solution Approach 1:
The system applies local quality by incorporating client-specific parameters within the standardized protocol buffer structure. Each client type can have customized fields or parameters localized to its specific needs while the overall buffer format remains consistent, enabling code reuse through standardization while accommodating client-specific requirements through localized parameter variations.
Data Source
AI summary
A system and method for per-client, per-type customizations to posts in an activity stream comprises an extraction pipeline and a rendering pipeline. The extraction pipeline can include a library of embedded code, data type taxonomy and an embed converter. The data type taxonomy is coupled to an activity source to receive activity information, and to produce a first protocol buffer. The embed converter produces a type-specific protocol buffer from the first protocol buffer and embedded code based in part upon the type of activity and the type of client. The type-specific protocol buffer is provided to the client to process activity information or present activity information. The disclosure also includes a method for processing a post in an activity stream on a per-client, per-type basis.
