In industrial projects, a tag is a unique identifier assigned to a physical item — a pump, valve, instrument, or piece of equipment — that links it to all relevant documentation, data, and records throughout the asset lifecycle.
Tag management is the discipline of creating, governing, and maintaining these identifiers to ensure consistency across engineering, procurement, construction, commissioning, and operations systems.
A single asset facility may contain tens of thousands of tagged items. Without a governed approach to tag creation and maintenance, inconsistencies accumulate rapidly: the same physical item may be referenced by different identifiers in the engineering system, the CMMS, and the supplier documentation — making it impossible to build a reliable picture of the asset.
Inconsistent tags are one of the primary causes of failed or incomplete document handover packages, and a major driver of data quality problems after commissioning. They also undermine data interoperability between connected enterprise systems.
Tags do not exist in isolation — they sit within an asset hierarchy that defines the parent-child relationships between systems, subsystems, and individual equipment items. Consistent tagging is what makes this hierarchy navigable and reliable across the full lifecycle.
In projects governed by CFIHOS or ISO 15926, tag numbering and attribute structures are defined against the standard's reference data — ensuring that tags carry consistent meaning across all systems involved in the project.
Sharecat's Central Tag Register gives owner/operators and EPCs a single, governed source of truth for all tag data. Tags are created within defined structures, linked to the asset hierarchy, and connected to all associated documentation — ensuring that tag data remains consistent from engineering through to operations and supporting reliable asset information management across the full lifecycle.
