WikiD Implementation Details

WikiD is a J2EE Servlet that contains an embedded OpenURL resolver (ORG.oclc.openurl.OpenURLResolver). Requests to the WikiD Servlet are transformed into OpenURL ContextObjects according to this plan:

In my OpenURL 1.0 implementataion, results are produced by running the ContextObject(s) through one or more AbstractService classes. The AbstractService classes invoked depend on the ServiceType entities identified in the ContextObject(s). In the case of WikiD, a single ContextObject with a single PrivateData ServiceType entity is the only possibility (see above).

In the OpenURL 1.0 protocol, PrivateData entities are interpreted relative to the Referrer. The WikiD.props file associates "Referrer: info:sid/oclc.org:referrer/WikiD" with the Java class ORG.oclc.openurl.app.entities.WikiReferrer. This is the class that interprets PrivateData entities in relation to the WikiD Referrer. In this case, we need a class capable of understanding a ServiceType PrivateData entity, which can be obtained via the method WikiReferrer.getPrivateDataService(). This method is hard-coded to return the AbstractService implementation ORG.oclc.openurl.app.services.WikiService, which is capable of processing ServiceType PrivateData requests in relation to the WikiD Referrer.

The constructor for WikiService looks at the value of the ServiceType PrivateData and constructs an AbstractAction class depending on the value of the "action" parameter. At this point, the WikiService class is ready to process the other entities in the ContextObject to produce the desired result.
