Managed Attributes

Managed attributes are those attributes that, unlike standard attributes, carry additional information in them, such as hierarchy, a set of predefined values, and a set of synonyms or ranks. This section describes how to build the necessary parts of the records schema (PDRs and DDRs) that define managed attributes themselves.

About managed attributes and their values
Managed attribute values represent specific value assignments on managed attributes in your data domain. Through managed attribute values, you can express hierarchical relationships and other useful information (such as synonyms and ranking), on record refinements in your data domain.
Summary of operations
You can add and list managed attribute values. You can optionally assign their names, synonyms, or ranks at creation time. You can also update the display name and the rank of the managed attribute values without stopping the data domain. You can delete managed attribute values by deleting the PDR that defines an associated managed attribute.
About ranks and synonyms
When you add managed attribute values, you can specify their synonyms and ranks.
Adding managed attribute values
Typically, you add more than one managed attribute value. To add a set of them, you first define a managed attribute with which the values will be associated. Next, you add the managed attribute values, associating them with the managed attribute.
Listing managed attribute values
You can list either all managed attribute values, or list only values added for a specific managed attribute with listManagedAttributeValues operation in the Configuration Web Service.
Deleting managed attribute values
You can only delete all managed attribute values for a specific managed attribute, by deleting its PDR (this deletes the associated DDR and all assignments on it). You cannot delete a single managed attribute value. Since managed attribute values are represented in the index as records, to delete them, you use the Data Ingest Web Service operations for deleting records.
About static ranking
When you add managed attribute values with PutManagedAttributeValues, you can add (and later update), the static ranking of the particular value, within this managed attribute. Static ranking affects how Endeca Server displays the values when returning refinements to the end users.
