Link scheme values and overrides

About link scheme values

The link scheme value instructs the WorldCat knowledge base how to create articles links for a particular record or set of records. The link scheme value is represented at the collection level and corresponds to the oclc_linkscheme column in the KBART file. Libraries can override the link scheme value on a per title basis.

The link scheme field is optional for many collections. OCLC recommends that libraries only attempt to add metadata to the field when it is truly necessary.

Collection-level link schemes

Custom collections of electronic serials use link schemes. Custom collections are those that are not in the global WorldCat knowledge base that you create via the "Create a Collection" button in the Collection Manager interface. Link schemes are needed to resolve to full text for articles. Without a link scheme, link resolution is to the journal home page. After you create a custom collection of electronic serials and add it to your knowledge base, OCLC will create a link scheme for your titles. You do not need to try to configure your own link schemes.

Print serials do not use link schemes and many eBook collections do not use link schemes. Test your eBook collection; if you are successfully accessing full text, you do not need a link scheme.

To find the Link Scheme field at the collection-level:

  1. Navigate to the collection. 
  2. Expand Linking and find the Link Scheme field.

How to request link schemes for knowledge base collections you create

Send the following information to OCLC Support:

  1. The Provider Name and the Collection Name.
  2. The Collection ID (in the Properties accordion of the collection).
  3. sample search from your current provider that resolves to full text.
  4. user name and password that will allow OCLC to proxy through to the full text.

 Note: It could take OCLC approximately two months to create your link schemes.

Find instructions to override proxy and provider ID settings

See Use Proxy and Override to override your institution’s proxy information or provider specific IDs per collection.

Title-level link schemes

For libraries that wish to create one collection with content from multiple, different platforms, or if a library has an individual title that requires special handling, the link scheme value can be overridden on a per title basis. The title-level link scheme value will be used when creating article links for the title instead of the collection-level link scheme value.

Contact OCLC Support for assistance in choosing the correct value.

How to override title-level link schemes

To attempt to override the setting yourself:

  1. See the Link scheme values spreadsheet to see the link scheme values that are supported by the WorldCat knowledge base.
  2. Navigate to the title-level settings by searching for the collection and clicking on it to open the collection.
  3. In the collection, expand the Titles accordion.
  4. Click on a title to open the title metadata.
  5. In the Linking Overrides section, edit the Override Link Scheme field so that the title link scheme will override the collection-level link scheme.
