A comparison of feature-level metadata and editor tracking (Aviation)

Both Esri Production Mapping and ArcGIS for Desktop provide ways for you to automatically populate the user name of the person who has created or modified a feature, as well as the date on which the feature has been created or modified. Both methods allow you to define the fields that are populated when a feature is created or modified and determine which action populates the field. However, there are some differences between the ArcGIS and 生产化制图 (Production Mapping) functionality, which are described in the table below.

When to use one method instead of the other

Editor tracking is recommended for the following situations:

Feature-level metadata is recommended for the following situations:

When both feature-level metadata and editor tracking are enabled on the database

Feature-level metadata is written as an extension to editing functionality, while editor tracking is built into the geodatabase. The fields selected as the Creator Field and Create Date Field for editor tracking are populated as soon as the feature is initially created. If one of these fields is also set as a feature-level metadata field that populates when a feature is created, the final value will be from the feature-level metadata because the extension is applied after the feature is created.

Fields selected as the Editor Field and Edit Date Field for editor tracking are handled differently than the create fields. These fields are designed to have their values set after a change occurs to a feature. If one of these fields is also set as a feature-level metadata field, the feature-level metadata value is applied, which triggers a change to the features. This means that the editor tracker will apply its value after the feature-level metadata and will be the final value.

Because the behavior is not consistent with the fields used for create and those used for updates, it is recommended that you choose one approach or the other.
