Updating a schema

When there are changes to your data source schema, you can update the schema in your template. With the updated schema, you can resolve any potential changes to the queries you included.

Before you begin

Important: Back up your template by saving a copy of it before you work with your schema.

Procedure

  1. In the Document Studio Outline view, right-click the schema that you exported and select Replace schema.
  2. Click Browse and select the .xsd file that you modified.
  3. Click OK. If all of the queries in the new data source schema resolve with the queries that were added to your template, then the schema is replaced and you are not required to make any further changes.

    If all of the queries in the new data source schema cannot be resolved, continue to the next step.

  4. If all of the queries in the new data source schema cannot be resolved with the queries that were added to your template, then you must select one of the following options:
    • Remove data references: Allow Rational® Publishing Engine to remove the queries from your template that cannot be resolved with the data source schema.
    • Specify valid replacement: Replace each unresolved query with a query that exists in the new data source schema.
  5. If you selected Specify valid replacement, in the Specify Valid Replacement window, specify replacement queries. Select the cell in the Replacement Name column to choose a query from a dropdown list.
