Creating a JSON Validation Scenario

Validation scenarios can be used to associate one or more JSON Schemas with a JSON document. Oxygen XML Editor Eclipse plugin also includes a built-in JSON Schematron Validator engine that can be specified in the validation scenario to validate JSON documents against a specified Schematron schema.

Creating a JSON Validation Scenario

To create a validation scenario, follow these steps:
  1. Select the Configure Validation Scenario(s) action in one of the following ways:
    • From the toolbar.
    • From the JSON menu.
    • From the Validate submenu, when invoking the contextual menu on a file in the Project Explorer view.

    Step Result: The Configure Validation Scenario(s) dialog box is displayed.

  2. Click the New button.

    Step Result: A validation scenario configuration dialog box is displayed.

    Figure 1. Validation Scenario Configuration Dialog Box
    This scenario configuration dialog box allows you to configure the following information and options:
    Name
    The name of the validation scenario.
    URL of the file to validate
    The URL of the main module that includes the current module. It is also the entry module of the validation process when the current one is validated. To edit the URL, click its cell and specify the URL of the main module by doing one of the following:
    • Enter the URL in the text field or select it from the drop-down list.
    • Use the Browse drop-down button to browse for a local, remote, or archived file.

    • Use the Insert Editor Variable button to insert an editor variable or a custom editor variable.

    File type
    The type of the document that is validated in the current validation unit. Oxygen XML Editor Eclipse plugin automatically selects the file type depending on the value of the URL of the file to validate field.
    Validation engine
    You can choose between the following types of validation engines for validating JSON documents:
    • Default engine - The built-in JSON Validator will be used. For JSON Schema documents, this type should not be chosen unless the document has a schema version specified.
    • JSON Schema Validator - This type is for JSON Schema documents only. It will use the version specified in the JSON Schema, or if a version is not specified, the JSON Schema draft-04 will be used.
    • JSON Schematron Validator - The built-in JSON Schematron Validator will be used to validation JSON documents against a specified Schematron schema.
      Note: For proper error localization, the root element of the Schematron schema should include the @queryBinding attribute with the value of xslt2 after the Schematron namespace declaration:
      <sch:schema xmlns:sch="http://purl.oclc.org/dsdl/schematron" queryBinding="xslt2">
    Automatic validation
    If this option is selected, the validation operation defined by this row is also applied by the automatic validation feature. If the Automatic validation feature is disabled in the Document Checking preferences page, then this option is ignored, as the preference setting has a higher priority.
    Schema
    Displays the specified schema.
    Specify Schema
    Opens the Specify Schema dialog box that allows you to set a schema to be used for validating JSON documents.
    Move Up
    Moves the selected scenario up one spot in the list.
    Move Down
    Moves the selected scenario down one spot in the list.
    Add
    Adds a new validation unit to the list.
    Remove
    Removes an existing validation unit from the list.
  3. Configure any of the existing validation units according to the information above. You can use the buttons at the bottom of the table to add, remove, or move validation units.
  4. Click OK.

Result: The newly created validation scenario will now be included in the list of scenarios in the Configure Validation Scenario(s) dialog box. You can select the scenario in this dialog box to associate it with the current document and click the Apply associated button to run the validation scenario.
