Mapping Metadata

The WorldCat Digital Collection Gateway enables you to map how your collection metadata appears in a WorldCat.org preview. You can adjust how records display in the WorldCat item detail and search results views. You can also view and map records in a MARC record preview. As you adjust how records appear in the different views, you are creating a map that affects how the entire collection is processed by the Gateway. In other words, changes to the map in one record affect all records in the collection. Likewise, changes to the map in one view affect all the views (WorldCat item detail, WorldCat search results, and MARC). The Metadata Map is saved as part of the Profile for each collection.

When you choose to edit the metadata map, the Digital Collection Gateway harvests metadata from the CONTENTdm Server and maps it. The records are then displayed for review. As you review and edit the map, the changes are checked to ensure valid MARC records. (Records are never loaded to WorldCat until you approve the map you have created.)

Note: We recommend you use the Qualified Dublin Core template in your collections to facilitate metadata mapping with WorldCat.

After your metadata map is adjusted to your satisfaction, you approve it and your first synchronization with WorldCat begins. An initial synchronization schedule for your collection is set at once per quarter, but you can adjust this using the Sync Schedule. For more information, see Scheduling Uploads.

Accessing the Metadata Map

The Digital Collection Gateway enables you to edit the metadata map through record previews.

Note: You can also log in to the Digital Collection Gateway directly by going to: http://worldcat.org/digitalcollectiongateway/Login.

To access the metadata map

  1. Open CONTENTdm Administration.

  2. Click the Server tab.

  3. Click Harvesting. The Server Harvesting page displays. If the server had been registered with the Digital Collection Gateway, a Login link displays in the WorldCat Sync section of the page.

  4. Click Login. The Digital Collection Gateway Login page displays.

  5. Enter your user name and password and then click Sign In. The WorldCat Digital Collection Gateway Home page displays.

  6. Click the Metadata Map Edit link for the collection. A progress screen may display as the map is loaded. The WorldCat Item View displays by default.

Selecting a Metadata Map Template

The first time you edit the metadata map for a collection, you can select a Metadata Map template. When you click the Metadata Map Edit link, the Select Metadata Map dialog box displays the template options of the System Default Template or the metadata map for another previously edited collection. Any changes you make to the Metadata Map affect only the current collection. In other words, changes you make to the Metadata Map for this collection do not propagate to other Metadata Maps.

Note: You can also choose a new metadata map template later by selecting Reset Metadata Map while on the Metadata Map Edit page.

Mapping Metadata

The Digital Collection Gateway provides several ways to edit the metadata map. Map changes are validated as you make them.

For each displayed field, you can perform the following mapping changes by clicking on the yellow box surrounding the field and selecting from the drop-down list. Each change you make to the map affects how all records in the collection are mapped.

  • No mapping — If you click No Mapping from the drop-down list, the current field is removed from the map. The metadata is not deleted from your CONTENTdm Server. The metadata is ignored as it is synchronized with WorldCat.

  • Replace — If you select another source metadata field from the drop-down list and click Replace, the currently displayed metadata field is replaced with the newly selected metadata field.

  • Add — If you select another source metadata field from the drop-down list and click Add, you will add the newly selected metadata field to the current position in the display. (Some elements of the WorldCat Item View, WorldCat Search View, and MARC View do not allow multiple fields to be displayed at once so your change may not be visible in the current view.)

To see more mappable fields in any display, click the More drop-down list at the top of the page, then select Show Unmapped Fields.

A template record with additional mappable fields will be on your source metadata. Each of the template record fields show up as metadata surrounded by a blue box. Click on the blue boxes to edit the mappings, the same way you would for other fields. To hide the template, click the More drop-down list at the top of the page, then select Hide Unmapped Fields.

You can edit the metadata map using any of the different views of the data and your collection: WorldCat Item View, WorldCat Search View and MARC view. You also can use the Collection-Wide Metadata Viewer, which provides a way to evaluate how frequently fields are used in this collection on your CONTENTdm server.

Each change you make to the map is immediately saved to the map. To undo all changes made to a map within a session, click Cancel. Or, save changes to work with later by clicking Finish Later.

You can restore the default map and remove any mappings you have made in the past by clicking the Restore Default Map link. In this dialog, you can select a metadata map template from a drop-down list.

To save changes, approve and sync, click Approve Map & Sync.

Navigating the Preview of Your Collection

While editing the Metadata Map, you can navigate through each record in your collection using either the grey arrows above the preview image, the navigation slider for relative movement in the preview of your collection, or by using the Go to Record option to navigate directly to a specific record.

Using the WorldCat Item View

The WorldCat Item View displays by default when you click the Metadata Map Edit link from the Digital Collection Gateway Home page. The item view is a preview of what the item's detailed display would look like in WorldCat, after a user discovers the item in search results and clicks to see more information.

The yellow, highlighted boxes show editable metadata mappings. Click to edit the mappings.

Use the Edit Mapping drop-down list to review and select mappings. The list displays the field name, as well as the contents of the field for the current record.

After you select a mapping, you can choose to add the selected field to the mapping, or replace the current mapping with the newly selected field. The WorldCat Item View updates to show the edited mapping, and the mapping change is applied to all records in the collection.

To unmap a field, click the yellow highlight box and select No Mapping from the Edit Mapping drop-down list. Click Replace. The mapping for this metadata field is removed across all records and all views.

You can also open a more accurate preview of the record without the highlight boxes by clicking the Open Preview in Separate Window link.

Material Type Mapping

You can use a wizard to assign the material type of each item in your collection to the material type icon and text in the Edition/Format field of the WorldCat Item View. To use the wizard, click the material type icon in the WorldCat Item View.

The Change Material Type Key window displays.

Following the steps in the wizard, you first select a Dublin Core Field from your collection's metadata that will be used to determine each item's material type. After you've selected a Dublin Core Field, the contents of this field for every item appear in the Field Contents column in Step 2. You can select a different material type for each value by double-clicking the associated value in the right column and selecting the new material type. Click OK to save changes and close the window.

Record Validation (Online)

Each record that is harvested for the preview is run through a MARC record validator. The validation status is displayed in the lower-right of the Viewer.

Use the arrows in the upper-right and upper-left to navigate items in the collection.

Using the WorldCat Search View

Access the WorldCat Search View by clicking the Metadata Map Edit link from the Digital Collection Gateway Home page, and then clicking the WorldCat Search View tab. The search view is what the user would see as a brief search result for the item, when metadata matches a WorldCat search query. (The thumbnail also would display in search results.)

Metadata mappings can be edited in the same way they are edited and previewed using the WorldCat Item View.

Using the MARC View

Access the MARC View by clicking the Metadata Map Edit link from the Digital Collection Gateway Home page, and then clicking the MARC View tab. The MARC View displays what happens in the background when the source metadata is translated to a MARC record.

Note: Fixed fields are not adjustable and display as an Internet Resource, Monograph in WorldCat.

Metadata mappings can be edited in the same way they are edited and previewed using the WorldCat Item View.

Analyzing the Source Metadata

The Gateway provides two tools that help you analyze the metadata for your collection: Dublin Core Summary and Frequency Analysis. To view the contents of each of the fields in your collection, click the More drop-down list at the top of the page, then select Open Dublin Core summary in new window. To view a Frequency Analysis of the metadata field names from your collection, click the More drop-down list at the top of the page, and select Open Frequency Analysis in new window.

Approving the Map

After you have edited the metadata map, you can approve the map and synchronize your collection with WorldCat from the Edit Metadata Map page.

To approve the metadata map

On the Edit Metadata Map page:

  1. Click Approve Map & Sync. A confirmation dialog displays. Click OK to save the approved map in the Profile for this collection and to start synchronizing the collection. A progress dialog displays.

  2. The Digital Collection Gateway Home page displays, with the collection’s Next Sync time updated, as the collection is harvested from the CONTENTdm Server and loaded into WorldCat.

Depending on the size of the collection, your changes will display in WorldCat as the synchronization completes.

After the synchronization completes, a WorldCat Sync Report is available in the Reports section of the Digital Collection Gateway (for more information, see Reviewing Reports). You can now synchronize the OCLC numbers from this synchronization into your CONTENTdm collection using CONTENTdm Administration. For more information, see Updating CONTENTdm Collections with OCLC Numbers.
