Adaptive Personalization Manual / Version 2110
Table Of ContentsCustomer segments represent groups of website visitors. Users belong to a segment if they satisfy the conditions associated with the respective segment, for example if a user is a premium user and at most 35 years old.
Segment conditions are stored in a property of a content type that represents segments in your application. In
CoreMedia Blueprint, this content type is called CMSegment
. These conditions
are used by the SegmentSource
to determine membership in a segment.
CoreMedia Adaptive Personalization offers a
CoreMedia Studio field editor for segment conditions called
ConditionsField
.
Configuring the SegmentSource
SegmentSource
is a ContextSource
implementation that evaluates segment conditions to
determine the current user's membership in a segment. The source evaluates the conditions in its
preHandle
method for each request. The conditions are applied to the contents of the
ContextCollection
at the time of invocation of preHandle
, thus the
SegmentSource
must be placed behind all other sources that provide context information used in the
segment conditions.
Membership in a segment is indicated by a property of the segment's simplified content id (content:<id>) of the document representing the segment. So a segment represented by content 42 will be mapped to the property 'content:42'. This property is set to the Boolean value 'true' if the user is a member of the segment; segments a user does not belong to are either not represented in the context or are assigned a value of 'false'.
The SegmentSource
requires a reference to the Cache
used for storing preprocessed
segment conditions and to the ContentRepository
to retrieve segment documents. Further, as with all
sources, you've got to provide the name of the context to be used to store the segment properties.
Optionally, you may configure in which folder of the repository the source looks for segment documents, the content type used to represent segments, and the name of the property of the content type that contains the segment conditions.
Property Name | Required | Default | Description |
---|---|---|---|
cache | Yes | Reference to the CoreMedia Cache to be used to store preprocessed segment conditions. | |
contentRepository | Yes | Reference to the content repository containing the segment documents. | |
contextName | Yes | Name to be used for the context containing the segment properties. | |
pathToSegments | No | /System/personalization/segments | Repository folder in which to look for segment documents. |
segmentDocType | No | CMSegment | Name of the content type used to represent customer segments. |
conditionPropertyName | No | condition | Property of the segment content type that contains the segment conditions. |

Configuring the property editor used for segment conditions
ConditionsField
is a property editor for conditions. This editor is configured similar to the
SelectionRuleField
by supplying the list of supported condition types and their mapping to user
profile properties.
Configuring the SelectionRulesField to offer conditions on customer segments
To enable conditions on customer segments in the SelectionRulesField
property editor, configure the
SegmentCondition
component. Make sure its propertyPrefix
attribute matches the name of
the context object used for storing segments in the CAE.
