getProviderList

public GraphNode getProviderList(@Context
                        javax.ws.rs.core.UriInfo uriInfo)

Returns a GraphNode containing a list of ConceptProviders stored in the content graph to be managed. The order in the list represents the priority of the providers. This resource is accessible through a GET request on the URI sub-path "edit-concept-provider-list".

updateConceptProviders

public javax.ws.rs.core.Response updateConceptProviders(List<String> types,
                                               List<String> sparqlEndPoints,
                                               List<String> defaultGraphs,
                                               List<String> queryTemplates,
                                               List<String> conceptSchemes)

Allows the list of ConceptProviders stored in the content graph to be updated with the list POSTed via the URI sub-path "update-concept-provider-list". The order in the list represents the priority of the providers.

Parameters:

types - specify the type of each ConceptProvider: either a LocalConceptProvider or a RemoteConceptProvider.

sparqlEndPoints - the SPARQL EndPoint to connect to in case of a RemoteConceptProvider.

defaultGraphs - the Graph to be queried in case of a RemoteConceptProvider.

queryTemplates - the template for the query to be used in case of a RemoteConceptProvider.

conceptSchemes - the concept scheme within which concepts are to be searched, in case of a LocalConceptProvider.

Returns:

- a 200 (OK) response if everything is fine. - a 400 (BAD REQUEST) response if types parameter is undefined.

getConceptProviders

public List<ConceptProvider> getConceptProviders()

Description copied from interface: ConceptProviderManager

Returns a list of ConceptProviders. The list order determines the priority of a ConceptProvider. The meaning of the priority is left to the implementation and application.

Specified by:

getConceptProviders in interface ConceptProviderManager

Returns:

a list of managed ConceptProviders.

getMenuItems

public Set<GlobalMenuItem> getMenuItems()

Description copied from interface: GlobalMenuItemsProvider

Returns a Set of GlobalMenuItemS. If there is no GlobalMenuItem available (e.g. the current user has not the needed permissions) then the returned set is empty.

Specified by:
