Governance in Zwiron has three components:
  • Glossary — a canonical dictionary of business terms and definitions
  • Classifications and Tags — a structured labeling system for sensitive or domain-specific data
  • Policies — documented rules for data access, masking, and retention
Go to Governance in the sidebar. The page has three tabs: Glossary, Classifications, and Policies.

Glossary

A shared glossary ensures that terms like MRR, active user, or LTV have a single, agreed-upon definition visible to everyone in the organization.

Term fields

Term statuses

Creating a term

  1. Click the Glossary tab
  2. Click New Term
  3. Enter the name, definition, and any synonyms
  4. Set the status (defaults to draft)
  5. Click Create

Editing a term

Click the pencil icon on any term to update its fields or change its status.

Deleting a term

Click the trash icon on any term. Deletion is permanent.

Searching

Use the search bar to filter terms by name or definition text.

Classifications and Tags

Classifications and tags provide a structured way to label data assets in the catalog.
  • A Classification is a category (e.g. Sensitivity, Data Domain, PII Type)
  • A Tag is a label within that category (e.g. Confidential, Finance, Email)
This two-level structure keeps labeling consistent. Instead of freeform strings like "sensitive" or "pii-email", your team picks from defined tags within defined categories.

Example taxonomy

Creating a classification

  1. Click the Classifications tab
  2. Click + New Classification
  3. Enter a name and optional description
  4. Click Create

Adding tags to a classification

  1. Click + Tag next to a classification
  2. Enter the tag name and optional description
  3. Click Create Tag
Tags appear nested under their parent classification.

Applying tags to catalog assets

Tags are applied in the Data Catalog, not here. Open any table in Catalog → click Tags in the overview panel → select from your defined tags.
The Governance page is where you define your classification taxonomy. The Catalog is where you apply tags to individual tables and columns.

Deleting a classification or tag

Click the trash icon next to any classification or tag. Applying tags that have been deleted will be removed from all catalog assets.

Policies

Policies are structured documentation records for data governance rules. They are not technical enforcement mechanisms — they define what the rules are so the whole organization has a shared reference.

Policy kinds

Creating a policy

  1. Click the Policies tab
  2. Click + New Policy
  3. Enter a name (e.g. Customer PII Access Policy)
  4. Select a kindaccess, masking, or retention
  5. Select the tags the policy applies to (from your taxonomy)
  6. Fill kind-specific fields (roles, masking method, retention days)
  7. Click Create

Seeing where a policy applies

On the Policies table, click the assets in scope action on a row. Zwiron lists catalog tables, views, and columns that carry any of the policy’s tags.

Seeing policies on a catalog asset

Open a table in Catalog (peek panel or full detail → Profile). The Applicable Policies section lists policies whose tags overlap the asset’s tags.

Column-level tags

Tags can be applied to individual columns, not only tables. On the asset detail Columns tab, click a column to open the tag editor. Prefer tagging email as Email rather than labeling the whole table when only one column is sensitive.

Permissions


What policies do not do

Policies are documentation only. They do not:
  • Block queries or exports
  • Mask column values in Catalog or downstream tools
  • Auto-delete data when retention expires
Treat them as the org’s written rules of record, linked to data through shared tag names. Runtime enforcement (warehouse masks, IdP controls, etc.) is outside Zwiron today.
  • Data Catalog — where classification tags are applied to assets
  • Data Quality — automated tests on catalog tables
  • Audit Logs — track who changed what in your organization
