TAL — Tag Attribute List

A structured list defining the attributes, metadata and data fields associated with Tags and tagged engineering objects.

Definition

A Tag Attribute List (TAL) is a controlled engineering document that defines the attributes, data fields, formats and validation requirements associated with Tags and the engineering objects they identify. It establishes the information requirements necessary to support engineering, operations, maintenance and lifecycle information management.

Why It Matters

Tag Attribute Lists define the engineering information associated with Tags and the assets, systems and engineering objects they identify.

In Practice

Tag Attribute Lists commonly define mandatory attributes, naming conventions, data types, validation rules and relationships used to ensure consistent engineering information across multiple systems.

Common Misuse

A Tag Attribute List defines the information required for each Tag, whereas a Tagging Specification defines the overall rules governing Tag identification and assignment.
