Namespace: VDS.RDF.Web
Assembly: dotNetRDF.Web.dll
Syntax
public class UpdateHandler : BaseSparqlUpdateHandler
Remarks

Used to create an Update endpoint at a specific fixed URL

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 Update Endpoint: 
<dotnetrdf:/folder/update> a dnr:HttpHandler ;
                                 dnr:type "VDS.RDF.Web.UpdateHandler" ;
                                 dnr:updateProcessor _:proc .

_:proc a dnr:SparqlUpdateProcessor ;
       dnr:type "VDS.RDF.Update.LeviathanUpdateProcessor" ;
       dnr:usingStore _:store .

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