BMS Metadata Tag Dictionary for Editable Automated Tagging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional building management systems (BMS) face challenges in efficiently managing metadata tagging, requiring manual and tedious processes for direct tagging and complex rule-based implied tagging, limiting user control and flexibility.
Innovation Solution
A system library with editable spreadsheet format is introduced, allowing users to define and add tags, with a computing system that imports controller applications, edits the library, and automatically adds tags to a tag dictionary, enabling user-controlled metadata management and conversion between tag syntax formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If direct tagging is used manually, then user control over metadata is achieved, but the process becomes tedious and time-consuming
Solution Approach 1:
The system pre-configures tag dictionaries and metadata schemas before the actual tagging process. Users can define tag structures, relationships, and validation rules in advance, so that when tagging occurs, the system already has the framework ready to automatically apply tags based on pre-established rules and patterns.
Solution Approach 2:
The system enables automatic tagging by allowing the BMS to self-assign metadata tags to entities based on pre-configured rules, device types, and patterns. The tagging process becomes self-service where the system automatically identifies entities and applies appropriate tags without requiring manual user intervention for each entity.
2Productivity
If implied tags are used automatically, then tagging efficiency is improved, but user control and flexibility are reduced
Solution Approach 1:
The tag dictionary is designed to be dynamic and configurable, allowing users to modify tagging rules, add custom tags, and adjust metadata schemas at any time. The system supports both automatic tagging based on current rules and manual overrides, enabling the tagging approach to adapt to changing user needs and requirements.
Solution Approach 2:
The system provides a universal tagging framework that can handle both automatic implied tagging and manual direct tagging through a single configurable interface. The tag dictionary serves multiple functions: it stores predefined tags, user-defined custom tags, validation rules, and relationships, making it a multi-functional tool that supports various tagging strategies.
3Extent of automation
If a sophisticated tag dictionary is constructed for implied tagging, then automatic tagging capability is achieved, but user flexibility to define unique metadata is limited
Solution Approach 1:
The tag dictionary is segmented into multiple independent sections: system-defined tags, user-defined tags, tag relationships, and validation rules. This segmentation allows users to access and modify specific portions of the tag dictionary without affecting the entire structure, enabling both automatic tagging functionality and user flexibility to coexist.
Solution Approach 2:
The system introduces an intermediary layer between the automatic tagging engine and the user-defined metadata. This intermediary tag dictionary acts as a mediator that translates user requirements into structured tags while maintaining the ability to support automated tagging processes. Users can define custom tags through this intermediary without breaking the automatic tagging framework.

AI summary
A building automation system (BAS) or building management system (BMS) can have metadata customization and/or metadata tagging management. The BAS comprises a system library and a computing system. The system library comprising a plurality of relationships between a plurality of tags and a plurality of entities. The computing system is communicatively coupled to the system library. The computing system is in communication with the system library. The computing system is configured to provide data from a system library file in a text format to a system library file in a spreadsheet format, edit the system library file in the spreadsheet format to include user defined tags, and add the user defined tags to a tag dictionary.
