Gets the link groups of a UNX universe published to a CMS repository.
In a relational universe, a link group is a set of business objects sharing a dependency link that is expressed in the universe data source model (data foundation) or the universe semantic layer model (business layer). A link group can be one of the following:
It is based on the data foundation and it expresses relationships between objects, such as a dimension and another dimension, or a dimension and a measure. A data link group can only contain dimensions and measures. A data link group can be seen as a measure group if it contains at least one measure.
It is based on the business layer and it expresses relationships between objects, such as a dimension and an attribute. A semantic link group must contain one dimension and its associated attributes if any.
A link group cannot be included into another link group. Link groups can have common dimensions or measures.
A universe contains at least one link group, otherwise it is empty.
