What Are Tags?

Tags are labels used to classify and organize assets registered in the catalog, and are part of the metadata.
Tags have a hierarchical structure, consisting of the following three levels:

Tag Group » Parent Tag » Child Tag

What Is the Tag Glossary?

The tag glossary is a QDIC feature for managing tags. Tags are categorized in the following hierarchy. Viewers can only browse.

Tag Group

A tag group is a collection of parent tags and serves as a major category in the tag glossary. Tag groups are used to organize tags in the tag glossary.

• Tag group names are unique within the entire tag glossary and do not overlap with other tag groups, parent tags, or child tags.
• Tag group names are not assigned to (or displayed on) assets.
• Tag groups have assigned colors. The tag display color in the catalog uses the color set for the tag group.

Parent Tag

A parent tag is a collection of child tags and serves as a mid-level category in the tag glossary.

• When assigning tags to an asset, parent tags and child tags are always assigned together as a set.
• The tag group to which a parent tag belongs may be changed later.
• Parent tag names are unique within the entire tag glossary and do not overlap with other tag groups, parent tags, or child tags.
• The display color in the catalog is the color set for the tag group to which it belongs.

Child Tag

A child tag is a sub-category in the tag glossary.

• When assigning tags to an asset, parent tags and child tags are always assigned together as a set.
• The hierarchy (parent-child relationship) between parent tags and child tags is fixed.
• Child tag names are unique within their parent tag.
• The display color in the catalog is the color set for the tag group to which it belongs.

Case Study - Example of Tag Structure

The following diagram shows an example of a tag structure to be created in Tag Glossary.

The following diagram shows the tags created in the tag glossary and their assignment to assets in the catalog.

Types of Tags by Assignment Method

Tags are classified into the following types based on how they are assigned to assets. The classification of tags to be assigned is determined by the administrator or operator.

Manual Tags

Tags that are directly assigned to assets by administrators or operators through manual operation are called manual tags.

Rule Tags

Tags that are automatically assigned to assets according to rules based on the state or property values of assets when the catalog is updated are called rule tags.

In most cases, when the following events occur and match the rule conditions, rule tags are assigned to or removed from assets. Rule tags are removed from assets if they no longer meet the rule conditions.

Differences Between Tags and Custom Properties

Both tags and properties are metadata for assets, but their purposes are different. Tags are metadata for classifying assets. On the other hand, custom properties are metadata for defining the attributes of assets.

Purpose of Tags

• Classify assets
• Improve searchability of assets in the catalog
• Visually emphasize classification through tag names and colors

Purpose of Properties

• Define asset attributes
• Store structured information. Information about assets may be recorded in a standardized format.
• Provide detailed information. Detailed information that cannot be expressed in text may be set for assets.
