About the Enterprise Vault classification properties

When an item matches a classification rule that you have defined, Enterprise Vault records the fact in the metadata properties of the item. The chosen property and the value that Enterprise Vault assigns to it determine what Enterprise Vault does with the item. As Table: Enterprise Vault classification properties explains, Enterprise Vault can process the classification values that are stored in four such properties.

Table: Enterprise Vault classification properties

Property

Description

evtag.category

This property assigns one or more category values to an item when the item is added to Enterprise Vault. For example, some of the example classification rules check the contents of items for credit card numbers and assign the category value "PII" (for "personally identifiable information") to those that do.

You can search for the assigned property values in applications such as Enterprise Vault Search, Compliance Accelerator, and Discovery Accelerator.

evtag.exclusion

In environments where you use Compliance Accelerator, this property instructs the random sampling feature of that application to ignore any item that Enterprise Vault has classified with the property. (Where appropriate, however, Compliance Accelerator users can still add these items to their review sets by conducting searches for them.)

For example, the example classification rules use this property to exclude auto-generated news feeds, charity solicitations, and other unimportant items from Compliance Accelerator review sets.

You can search for the assigned property values in applications such as Enterprise Vault Search, Compliance Accelerator, and Discovery Accelerator.

evtag.inclusion

In environments where you use Compliance Accelerator, this property instructs the random sampling feature of that application to capture any item that Enterprise Vault has classified with the property. For the best results, use this property selectively to prevent Compliance Accelerator from randomly sampling an excessive number of items.

For example, the example classification rules use this property to include Company Confidential items and items that contain financial or legal data in Compliance Accelerator review sets.

You can search for the assigned property values in applications such as Enterprise Vault Search, Compliance Accelerator, and Discovery Accelerator.

evaction.discard

By assigning the name of a retention category to this property of an item, you can mark the item for deletion. For example, one of the example classification rules uses this property to delete automated out-of-office messages.

The way in which Enterprise Vault handles such items depends on the point at which it classifies them.

  • During indexing. If an item is classified when Enterprise Vault indexes it, Enterprise Vault sets the retention category of the item to the evaction.discard property value. You can no longer search for the item, but, for a limited number of days, you may be able to recover it. This is the case even if, in the archive settings for your Enterprise Vault site, you have chosen to disable the recovery of user-deleted items.

  • During automatic expiry. If an item is classified because its retention period has expired, Enterprise Vault immediately deletes the item.

  • During user deletion. If an item is classified because a user has tried to delete it then, depending on how you have configured the archive settings for your Enterprise Vault site, the item is either immediately deleted or temporarily recoverable.

This property overrides the other classification properties, such as evtag.inclusion. So, if one classification rule marks an item for deletion then it is deleted, even if a second rule tags the item for inclusion in a Compliance Accelerator review set.

Some items may not be eligible for deletion because, for example, they are on legal hold. Where this is the case, the classification feature updates the item's retention category but does not delete the item.

All four properties are of type Multiple Choice List: you can assign several values to them. For example, an email that the example classification rules have processed could have two values assigned to its evtag.category property, "Many attachments" and "Personal", to indicate that it has ten or more attachments and that its author has assigned a sensitivity level of Personal to it. The evaction.discard property differs slightly because although it too is a Multiple Choice List property, Enterprise Vault uses the first assigned value only.
