📖Data Glossary

The Data Glossary lets you define and manage business terminology and definitions for your organization. Terms are organized by domains, so you can scope definitions to different parts of your data model (e.g., Sales, Finance, Marketing).
What Is the Data Glossary?
A glossary term is a named business concept with:
Name — The canonical term (e.g., "Customer", "ARR", "Churn")
Description — What it means in your organization
Domain — Which domain it belongs to (terms are scoped to domains)
Owner — Who is responsible for the definition
Synonyms — Alternative names (e.g., "Client" for "Customer")
Tags — Labels for filtering and grouping
Glossary terms appear as resources in the data graph and can be used by the AI assistant and EQL to understand your organization's vocabulary.
Creating a Term
Go to Data Glossary in the navigation.
Click Add term.
Fill in:
Name — Required, unique within the domain
Domain — Select the domain (create domains in Account Settings → Domains first)
Description — Required
Owner — Defaults to you if left empty
Synonyms — Optional list of alternative names
Tags — Optional labels
Click Create.
You must have at least one domain before creating terms. Create domains in Account Settings → Domains.
AI-Assisted Suggestions
When editing a glossary term, Euno can help suggest glossary content from related data assets.
Suggest description — Uses the term's selected related resources or defining EQLs to draft a description. The draft is added to the description field when the AI run finishes, so review it before saving.
Suggest related resources — Uses the term name, description, domain, synonyms, and tags to find likely related data assets.
Stop — Appears while an AI suggestion is running. Use it to cancel the current AI run before it applies a result.
If a suggestion button is disabled, the AI suggestions box explains what is missing. For example, you may need to select a domain, add related resources, add a defining EQL, or save the term before running the suggestion.
Editing and Deleting Terms
Edit — Click the menu (⋮) on a term and choose Edit. Update any field and save.
Delete — Click the menu and choose Delete. Confirm to remove the term.
When editing, you can move a term to a different domain. The name and synonyms must remain unique within the new domain.
Integration-managed terms
Some source integrations can create linked glossary terms. These terms show a Managed by source badge. The source integration owns the description and refreshes it during crawls, so the description cannot be edited in Euno. The name, owner, domain, synonyms, tags, external links, and related resources remain editable.
Integration-provided related resources are maintained separately from your manual selections or defining EQL, so source refreshes do not overwrite those edits.
For Omni, an administrator can enable Ingest topic ai_context as glossary terms in the source's Advanced Settings. Each topic with non-empty ai_context becomes a linked term, initially in the Universal domain. Euno removes it after a later crawl if the AI context is removed or the setting is disabled.
Searching and Filtering
Search — Type in the search box to match term names or synonyms (case-insensitive).
Domain filter — Filter by one or more domains.
Owner filter — Filter by owner.
Tags filter — Filter by tags (AND logic: term must have all selected tags).
Export
Click Export to download the glossary as a ZIP file containing YAML files, one per domain. Use this for backup, version control, or sharing definitions across environments.
Related Concepts
Domains — Logical groupings of resources. Glossary terms belong to domains. See Domains.
Context Issues — Capture missing institutional knowledge. Glossary terms help encode that knowledge. See Context Issues.
