  - getProjectAreaAssociations
```
protected abstract ProjectAreaAssociations getProjectAreaAssociations(URI resource)
```
    Returns the project area associations of the given resource's project
    
    Parameters:
    
    resource - the resource URI
    
    Returns:
    
    the project area associations of the given resource's project
  - getLinkIndexQueries
```
protected Collection<LinkIndexQuery> getLinkIndexQueries(ProjectAreaAssociations projectAreaAssociations,
                                                         URI resource,
                                                         URI resourceType,
                                                         URI gcURL)
```
    Returns the collection of link index queries to execute in order to discover all the incoming links on the given resource.
    
    Parameters:
    
    projectAreaAssociations - the project area associations for the given resource's project
    
    resource - the local resource to get incoming links for, i.e: the target resource of the returned link index queries
    
    resourceType - the given resource's type
    
    gcURL - the global configuration URL
    
    Returns:
    
    the collection of link index queries to execute in order to discover all the incoming links on the given resource
  - discoverIncomingLinks
```
protected ResourceResponse<Collection<DirectedLink>> discoverIncomingLinks(LinkIndexQuery linkIndexQuery)
                                                                    throws LinkingTypesStoreException
```
    Discovers the incoming links on the target resources of the given link index query.
    To discover the incoming links this method does the following:
    
    Execute the given link index query
    Reverse the resulting directed links, so we have the incoming links to display on local resources rather than the outgoing links owned by the remote application
    Parameters:
    
    linkIndexQuery - the link index query to execute
    
    Returns:
    
    the response containing the collection of discovered incoming links
    
    Throws:
    
    LinkingTypesStoreException - if an error prevents link types from being retrieved.
