HTTP Handler for adding SPARQL Graph Store HTTP Protocol for RDF Graph Management endpoints to ASP.Net applications
Inheritance
System.Object
BaseSparqlHttpProtocolHandler
ProtocolHandler
Inherited Members
Namespace: VDS.RDF.Web
Assembly: dotNetRDF.Web.dll
Syntax
public class ProtocolHandler : BaseSparqlHttpProtocolHandler
Remarks

Used to create a Protocol endpoint at a specific fixed URL, if you want to allow URIs relative to this URI to be used to refer to Graphs then use the WildcardProtocolHandler instead

This Handler is configured using the new Configuration API introduced in the 0.3.0 release. This requires just one setting to be defined in the <appSettings> section of your Web.config file which points to a Configuration Graph like so: 

<add key="dotNetRDFConfig" value="~/App_Data/config.ttl" />
The Configuration Graph must then contain Triples like the following to specify a Protocol Endpoint: 
<dotnetrdf:/folder/protocol> a dnr:HttpHandler ;
                                   dnr:type "VDS.RDF.Web.ProtocolHandler" ;
                                   dnr:protocolProcessor _:proc .

_:proc a dnr:SparqlHttpProtocolProcessor ;
       dnr:type "VDS.RDF.Update.Protocol.LeviathanProtocolProcessor" ;
       dnr:usingStore _:store .

_:store a dnr:TripleStore ;
        dnr:type "VDS.RDF.TripleStore" .
