Date Properties and Versions

There are three data properties available on objects which may have versions:

  • Created Date - The date when an object of authored model was created, including custom model objects (e.g. glossary terms). Note that this attribute does not apply to imported objects (e.g, tables, columns) except the repository model object itself.
  • Updated Date - The date when an object of authored model was last updated, including custom model objects (e.g. glossary terms). For imported objects, it is the date when the object was last updated in the repository (and not in the source system), or when it was created in the repository.
Information note

When re-harvesting an existing imported model so, all objects in the model have an updated date determined by the date of the import operation.

  • Viewed Date - The last time the current user visited the detail page of the object.

For objects authored in the repository, like glossary terms, the created date and updated date are maintained automatically.

However, for imported objects the created date is only available for the imported model, not any of the contained models or other objects. Thus, for these internal imported objects, only updated date is available.

Making any change to an attribute (if editable), custom attribute, etc., on the object will set the updated date.

Date Properties

/ type of objects

Imported Object

(e.g. Schema, Table, Column)

Custom Object

(e.g. Term)

Created Date

When the object was created on the imported tool such as when the database DDL’s CREATE TABLE statement was executed, note that:

  • Created Date is not available on all imported tool technologies, and therefore may not be set.
  • All columns have the same Created Date, as the Table they belong to, as all databases do not track column level changes.

When the object was created in Talend Data Catalog .

Modified Date

When the object was last modified on the imported tool such as when the last database DDL’s ALTER TABLE statement was executed. Note that:

  • Modified Date is not available on all imported tool technologies, and therefore may not be set.
  • If a table has not been modified, the Modified date is the same as the Created Date (to avoid double query).
  • All columns of a given table have the same Modified Date as the Table they belong to, as all databases do not track column level changes.
  • Modified Date are populated from properties that might have slightly different names in the imported tool such as Snowflake table last altered time.

Not Available

Imported Date

The last time the object was imported (possibly after incremental harvesting), which might be newer than the Created or Modified Date. This date is critical to assess the freshness / accuracy of the Created and Modified Dates, when the import is manual, or on a slow pace weekly / monthly schedule.

Not Available

Not Available

The same time as the Modified Date, or newer when the last data documentation happened in in Talend Data Catalog , such as setting or changing the Business Name, Description, or any custom attribute

When the object was updated in Talend Data Catalog .
