Open Data catalog in your SourceMedium workspace to see your data the way a connected AI agent sees it. It is the same catalog the agent searches, so a name you find here is a name the agent can use. Every member of the workspace can open it. Admins and Editors can write notes.

​
Tables

Each row is a table an agent can describe: its name, what it holds, its dataset, how many columns it has and the date of its latest data. Search by a table name or a word from its description.
  • Reporting tables are SourceMedium’s models. Their numbers follow the definitions under Metrics.
  • Raw tables are the source tables you chose under Warehouse → Raw data, once delivered. They hold source rows as extracted, not reconciled to reporting.
  • Not readable by agents marks a table the catalog documents that is outside what your agents can query.
Open a table to see its columns, their types and descriptions, which columns are keys, and the note your team wrote about it.

​
Metrics

Each row is a metric definition: what it means, its category and the table it is computed from. Open How it is calculated to see the calculation and the metrics it depends on. When you ask an agent for one of these metrics by name, it applies this definition instead of writing its own.

​
Preferences

What your team tells agents about your data: analysis preferences for the whole workspace, explanations of individual tables, and the Google Sheets your warehouse reads from. Agents on current tools read these before they answer. Notes do not change your warehouse or its calculations.

​
If the catalog is unavailable

Tables and Metrics are read from your warehouse. If it cannot be read, the page says Catalog unavailable; reload to try again. Your saved notes do not depend on it and stay available under Preferences.
