When the
isAutoGen property of a JSON attribute is set to true
("isAutoGen" : true), the name of the attribute becomes the
name of an the automatically generated dimension. This rule applies only to
attributes with the parameter
"ecr:type" : "dimension".
Dimension values for flat dimensions,
however, are not named explicitly in the JSON documents that configure the
dimensions. Instead, the "sourcePropertyNames" attribute
parameter specifies the names of one or more source record properties, each of
whose values will be used as a dimension value in the flat dimension.
For example, the following JSON attribute specifies that the value of
every property in your source records named
video_capability will become a dimension value of a
flat dimension named
camera.video_capability:
"camera.video_capability" : {
"displayOrder" : 7,
"ecr:type" : "dimension",
"isAutogen" : true,
"sourcePropertyNames" : [ "video_capability" ]
},Thus, if three different source records each have a property named
video_capability, set to
Slow,
Regular, and
Fast respectively, the flat dimension named
camera.video_capability will contain dimension values
named
Slow,
Regular, and
Fast.
Also note that a source record can have different properties, each of
which matches the
sourcePropertyNames value in a different dimension.
Thus, a single Endeca record might be tagged to the dimension value
green in the dimension
Color, to
Camera in the dimension
category, and to $150 - $200 in the dimension
Prices.
Note
The JSON attributes do not define hierarchic relationships among
the dimension values. That is, these attribute definitions cannot specify which
dimension values are parents or children of other dimension values. You must
specify these relationships among dimensions values in
rs_baseline_dimvals.xml.

Configuring dimension values for hierarchical dimensions.
