# MPE_DATACATALOG_LIBS
|
|
|
|
The `MPE_DATACATALOG_LIBS` table catalogs library attributes such as engine, paths, permissions, owners & schemas.
|
|
|
|
More frequently changing attributes (such as size and number of tables) are stored in [MPE_DATASTATUS_LIBS](/mpe_datastatus_libs).
|
|
|
|
To ignore additional librefs, or to trigger a scan, see the Refresh Data Catalog [instructions](https://docs.datacontroller.io/admin-services/#refresh-data-catalog).
