About the Enterprise Vault index properties
When an item matches a Veritas Information Classifier policy that you have defined, Enterprise Vault records the fact in the metadata properties of the item. The chosen property and the tag that Enterprise Vault assigns to it determine what Enterprise Vault does with the item. You can search for the assigned tags in applications such as Enterprise Vault Search, Compliance Accelerator, and Discovery Accelerator.
As Table: Enterprise Vault index properties for classification explains, Enterprise Vault can process the tags that are stored in four predefined properties only.
Table: Enterprise Vault index properties for classification
This property assigns one or more category values to an item when the item is added to Enterprise Vault. For example, you may want to assign the category value "US-PII" to items that contain U.S.-centric personally identifiable information, such as a North American telephone number or postal address.
In environments where you use Enterprise Vault 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, you may want to use this property to exclude auto-generated news feeds, charity solicitations, and other unimportant items from Compliance Accelerator review sets.
In environments where you use Enterprise Vault 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, you may want to use this property to include company-confidential items and items that contain financial or legal data in Compliance Accelerator review sets.
By assigning the name of a retention category to this property of an item, you can mark the item for deletion.
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 assigns to the item the retention category that you have chosen in the Veritas Information Classifier. 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 Veritas Information Classifier policy marks an item for deletion then it is deleted, even if a second policy 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.
You can assign several tags to each of the four properties. For example, an email that the built-in Veritas Information Classifier policies have processed could have two values assigned to its evtag.category property, "Intellectual-Property" and "Corporate-Ethics", to indicate that it may contain both intellectual property source code and terms that deviate from your corporate code of conduct. The evaction.discard property differs slightly because, although you can assign several tags to it, Enterprise Vault uses the first assigned tag only.
