About this task

After exploring the semantic categories of data as outlined in Exploring semantic categories of data columns, the wizard opens on a chart which represents the results of matching column metadata and new semantic concepts with concepts from the ontology repository.

A new Semantics line is added to the table. This line corresponds to the attributes found in the ontology repository as a result of the match operation.

The most relevant concepts are selected by default and all columns associated with the concept are highlighted in the table.


  1. If required, select another concept in the chart
    The generated analysis will be based on this selection.
  2. Click Next to open a new page in the wizard where you can configure what to enrich the ontology repository with.
