Overview of externally-created dimensions

An externally-created dimension describes a logical hierarchy of a data set; however, the dimension hierarchy is transformed from its source format to Endeca compatible XML outside of Developer Studio.

The logical hierarchy of an externally-created dimension must conform to Endeca’s external interface for describing a data hierarchy (found in external_dimensions.dtd) before you import the dimension into your project. Once you import an externally-created dimension, its ownership is wholly transferred to Developer Studio, so that afterwards you can modify the dimension with Developer Studio.
