Published versus embedded data sources

You can create data sources in Tableau when you connect to data. After you set up the data sources in Tableau, you can publish data sources as standalone resources, or you can publish workbooks with the data sources embedded in.

Unless you take actions to publish the data source separately, the data source is published as embedded in a workbook by default. For more information, see the Tableau documentation on Publishing data separately or embedded in workbooks.

Collibra Data Lineage ingests metadata of data sources as assets of the Tableau Data Model asset type, regardless of the way the data sources are published.

eTDM and pTDM

When you ingest a Tableau data source in Collibra, each asset is identified as eTDM or pTDM with [eTDM] or [pTDM] added to the asset name.

eTDM stands for embedded Tableau Data Model, which indicates that the asset represents the data source that is embedded in a workbook in Tableau. pTDM stands for published Tableau Data Model, which indicates that the asset represents the data source that is published separately in Tableau.

For a data source that is both published separately and embedded in a workbook, Collibra Data Lineage ingests the metadata in one of the following ways:

• If the metadata of the embedded data source matches that of the published data source, Collibra Data Lineage ingests the metadata only from the published data source to avoid duplication.
• If the metadata of the embedded data source contains more fields than that of the published data source, Collibra Data Lineage ingests metadata from both the published and embedded data sources.

As a result, a Tableau workbook can have one of the following relations:

• To the published and embedded data source.

• To the published data source only.
