To narrow the search, you could use other arguments of the
findConcepts
method (search qualifiers, names, external identifiers, or external links).
The next step is to go through the concepts, find the WSDL documents they cor-
respond to, and display the organizations that use each document:
// Display information about the concepts found
Collection specConcepts = br.getCollection();
Iterator iter = specConcepts.iterator();
if (!iter.hasNext()) {
System.out.println("No WSDL specification concepts found");
} else {
while (iter.hasNext()) {
Concept concept = (Concept) iter.next();
String name = getName(concept);
Collection links = concept.getExternalLinks();
System.out.println("\nSpecification Concept:\n\tName: " +
name + "\n\tKey: " + concept.getKey().getId() +
"\n\tDescription: " + getDescription(concept));
