Using predefined expressions to validate stand-alone metadata

You can use the Metadata check to validate metadata element values contained in stand-alone documents (stored in .xml format) using a series of predefined expressions. A single Metadata check can be configured to validate multiple file-based metadata resources, and for each resource multiple metadata element values can be validated to ensure that element values are correct and adhere to your organization's metadata requirements.

Once you have defined the criteria for the check, you can configure the notes and a severity rating. The notes allow you to provide a more specific description for the feature that has been written to the Reviewer table and are copied to the Notes field in the Reviewer table. The severity rating allows you to indicate how important the results from a check are in terms of your quality assurance/quality control processes. The lower the number, the greater the priority the check's results have.

步骤:

1. Start ArcMap.
   提示:

   If the ArcMap - Getting Started dialog box appears, you can open a new or existing map document. You can also check the Do not show this dialog box in the future check box and click Open.

2. On the main menu, click Customize > Toolbars > Data Reviewer.
3. Create a batch job and add the Metadata Check from the Advanced Checks group.

   The Metadata Check Properties dialog box appears.

   
4. If necessary, type a unique name for the check in the Check Title text box.
   注意:

   The check title can be used to describe the type, metadata standard, and conditions you are evaluating with the check. This is useful when you have a combination of mandatory and optional metadata elements and resources to be evaluated.

5. In the Metadata Location Type area, choose the Folder (for standalone XML files) option.
6. Click Browse to choose the folder that contains the stand-alone metadata resources you want to validate.
   注意:

   Only one folder resource (excluding child folders) can be evaluated per check. If you need to evaluate multiple folder workspaces, you need to configure a Metadata check for each folder.

   
7. In the Metadata Sources tree view, check the check box next to each stand-alone metadata document you want to validate.
   提示:

   Alternatively, you can click Select All or Clear All buttons to select or unselect all workspace items at once.

8. Click the Metadata Standard drop-down arrow and choose the metadata standard you want to use when identifying the metadata element.

   The standard you choose should match the metadata standard on which the stand-alone metadata resources are based.

   注意:

   The standard selected in this step determines the element identifier results that are captured in the Reviewer table's IDENTIFIER field during execution of the check.

   提示:

   You can also choose a custom metadata schema by choosing the Select Custom Schema item from the Metadata Standard drop-down list.

   The Browse to schema root dialog box appears.

9. Navigate to the root schema .xsd document you want to validate your stand-alone metadata items against.
   注意:

   Correctly identifying the root schema document is important to obtaining an accurate and complete validation of your metadata schema. Consult the author of your custom metadata schema if there is any doubt.

10. In the Check Options area, check the Validate Metadata Content check box, then click Configure to configure metadata element expression.

    The Metadata Content Validation dialog box appears.

11. In the Element Expressions area, click the Pre-Defined Expression drop-down arrow and choose the predefined expression you want to use when evaluating metadata element content.
    
12. In the Element Expressions area, expand the Metadata Element tree view and check the check box next to the metadata element that you want to evaluate with the predefined expression.
    注意:

    The Metadata Element drop-down list remains disabled until you choose a predefined expression.

    

    提示:

    To expedite check configuration, you can choose multiple metadata elements for evaluation against the currently selected predefined expression.

13. In the Element Expressions area, click Add Expression to add the metadata element or expression pair to the list in the Configured Expressions area.
    注意:

    Each metadata element configured for content evaluation is represented as a single row in the Configured Expressions list.

14. If necessary, configured element/expression pairs can be removed individually or in groups from the check by doing the following:
    1. individually selecting or selecting groups of checks with the shift or Ctrl keys in the Configured Expressions list.
    2. Right-click a selected row and choose Remove Selected to remove the selected expressions.
       
15. Click OK to close the Metadata Content Validation dialog box.
16. If necessary, type descriptive text for the check results in the Notes text box in the Reviewer Remarks area.
17. If necessary, click the Severity drop-down arrow and choose a value that indicates the priority of the check's results in the Reviewer Remarks area.
18. Click OK.
19. Save the batch job.
20. Click OK.
