A semantic layer is a configurable set of display names for columns in a data set. You can use this to create user-friendly labels for your data. For example, instead of pft_mgn_dol as a column header name, you could use a semantic layer to change it to Profit Margin Dollars, allowing anyone using the data to understand what that attribute represents. A semantic layer does not replace the original naming.
Using a semantic layer combined with Create a Data Dictionary can be very useful in clarifying the content of your data.
Creating a Semantic Layer
When importing the data set into Summit, a Field Name will be created in the metadata for each attribute (column) in the data set. This field name cannot be edited or changed because it is a copy of the column name from the data source. Once the data set is in Summit, however, you can create a semantic layer by updating or changing the name of the field. Use the following steps:
- Select the large title and delete the existing text.
- Enter your desired name for that attribute.
