This document describes how to create and use business glossary content in Dataplex.

Business glossary provides a single place to maintain and manage business-related terminology and definitions across the organization. It lets you attach terms to the columns of cataloged data entries.

You can use Dataplex business glossary to do the following:

• Create and maintain business glossaries, categories and terms.
• Use categories to represent hierarchical structures of categories and terms.
• Establish relationships between terms as synonyms or related terms.
• Attach terms to data entry columns.
• Browse and filter terms within business glossary.
• Display related terms and data entries for a given term.
• Search for data entries tagged by a particular term.
• Display related terms for a given data entry.

Terminology

This section describes the terminology used in this document.

Business glossary

Business glossary is a repository that provides appropriate vocabularies, and governs the business terms of an enterprise, along with the associated term definitions and relationships between the terms. It provides a single place to maintain and manage business terms and their definitions. A business glossary has the following property displayed in the console:

• Overview: a free-form rich-text description of business glossary purpose and content.

Category

A category is defined within a business glossary. It lets you organize and structure various categories and terms. You can nest categories up to three levels. The following are the properties of a category:

• Category: a relationship used to establish the container of the current category, if any.
• Description: a free-form rich text business definition of the category.
• Data Steward: specifies the person responsible for maintaining the category. This is a descriptive property and it doesn't affect the permissions on the category.

Term

A term is defined within a business glossary either in the glossary directly or within any category found in the glossary. It describes a concept used in a particular branch of business within an enterprise. A term has the following properties displayed in the console:

• Category: a relationship used to establish the container of the current term, if any.
• Description: a free-form rich text business definition of the term.
• Data Steward: specifies the person responsible for maintaining the term. This is a descriptive property and it doesn't affect the permissions on the term.

You can attach terms to the columns of a data entry to indicate that the columns are described by those terms.

Synonym

A synonym is a relationship used to indicate semantic similarity or equivalence between two different terms. It is used when two similar terms are defined by different teams in different glossaries. For example, earnings and income.

Related term

A related term is a relationship used to indicate that two terms are semantically related, yet different. For example, profit and income.

Before you begin

Limitations

• The bulk import of terms into a business glossary isn't supported.
• The business glossary feature is only supported in the Google Cloud console.
• When you search for data entries on the Dataplex Search page, the search result includes data entries where one of their attached terms matches the term used for search. However, reference to the matched term isn't displayed in the search result.
• BigQuery Omni regions aren't supported. You can't create business glossary content or attach terms to data entries in these regions.

Required roles and permissions

To get the permissions that you need to create and manage glossaries, ask your administrator to grant you the following IAM roles on the project:

• Full access to glossaries, categories, and terms: DataCatalog Glossary Owner (roles/datacatalog.glossaryOwner)
• Read glossaries, categories, and terms, create attachments between terms, and create attachments between terms and data entries: DataCatalog Glossary User (roles/datacatalog.glossaryUser)
• Read-only access to glossaries, categories, and terms: DataCatalog Entry Viewer (roles/datacatalog.entryViewer)

For more information about granting roles, see Manage access to projects, folders, and organizations.

These predefined roles contain the permissions required to create and manage glossaries. To see the exact permissions that are required, expand the Required permissions section:

Locate glossaries and terms

To navigate across your business glossary content, use the glossary and terms tree on the Dataplex Glossaries page.

You can use the filter bar on the Dataplex Glossaries page to locate categories by display name or terms based on a criteria. The filter returns items with any attributes matching the filter query. You can also use the following qualifiers:

• parent:VALUE: highlights the terms whose parent glossary name or description matches VALUE. For example, parent:Finance highlights the terms connected with the parent glossary name or description containing the phrase Finance.

• contact:VALUE: highlights the terms where the data steward is VALUE. For example, contact:[e-mail] highlights the entries connected to terms with data steward matching [e-mail].

• synonym:VALUE: highlights the terms that have at least one synonym with name or description matching VALUE. For example, synonym:interest highlights the terms that have related terms with name or description containing the phrase interest.

• related_to:VALUE: highlights the terms that have at least one related term with name or description matching VALUE. For example, related_to:discounting highlights the terms that have related terms with name or description containing the phrase discounting.

Search for data entries using terms

You can use the Dataplex business glossary content when searching for entries on the Dataplex Search page.

Note: In this section, the phrase "entries connected to a term" refers to the entries with at least one column containing an attached term.

The following search scenarios are supported:

• Simple search: The search query is specified as free-form text that captures term name or description. Search results include entries connected to a term with name or description matching the search query. These results are displayed alongside the results fetched from the other ways of matching that are unrelated to business glossary content.

  Note: The search result returns the entries connected to terms matching the search query. However, the source of the match isn't displayed in the search result.

• Search using qualifiers: The search query is specified as term:VALUE. The search result includes entries connected to a term where a substring of name, description, or data steward matches VALUE.
