1. The user requests a CodedNodeSet using getCodingSchemeConcepts.

   LexEVS:RequestCodedNodeSet Snippet LexEVS:RequestCodedNodeSet Snippet

2. The server calls the Distributed LexBIG getCodingSchemeConcepts method, returning to the server an org.LexGrid.LexBIG.Impl.CodedNodeSetImpl (the implementation of org.LexGrid.LexBIG.LexBIGService.CodedNodeSet) object.
3. The server then creates an org.LexGrid.LexBIG.cagrid.LexBIGCaGridServices.CodedNodeSet.service.globus.resource.CodedNodeSetResource. This Resource will be used to hold the instance of org.LexGrid.LexBIG.Impl.CodedNodeSetImpl, the implementation of org.LexGrid.LexBIG.LexBIGService.CodedNodeSet that was created above.
4. The server returns an org.LexGrid.LexBIG.cagrid.LexBIGCaGridServices.CodedNodeSet.stubs.types.CodedNodeSetReference object to the client. This is the reference to the CodedNodeSet Service Context. This object has a direct reference to the Resource created above. The user now uses this client to make transparent Grid calls through the Service Context.
5. The client may continue to make statefull calls to the CodedNodeSetClient and the assigned Resource.
6. These restrictions are separate calls but statefully maintained on the server via the Resource.

2. The server calls the Distributed LexBIG getNodeGraph method, returning to the server an org.LexGrid.LexBIG.Impl.CodedNodeGraphImpl (the implementation of org.LexGrid.LexBIG.LexBIGService.CodedNodeGraph) object.
3. The server then creates an org.LexGrid.LexBIG.cagrid.LexBIGCaGridServices.CodedNodeGraph.service.globus.resource.CodedNodeGraphResource. This Resource will be used to hold the instance of org.LexGrid.LexBIG.Impl.CodedNodeGraphImpl, the implementation of org.LexGrid.LexBIG.LexBIGService.CodedNodeGraph that was created above.
4. The server returns an org.LexGrid.LexBIG.cagrid.LexBIGCaGridServices.CodedNodeGraph.stubs.types.CodedNodeGraphReference object to the client. This is the reference to the CodedNodeGraph Service Context. This object has a direct reference to the Resource created above. The user now uses this client to make transparent Grid calls through the Service Context.
5. The client may continue to make statefull calls to the CodedNodeGraphClient and the assigned Resource. For example, the client may add Restrictions to the CodedNodeGraph before a Resolve:

2. The server calls the Distributed LexBIG getGenericExtensions method, returning to the server an org.LexGrid.LexBIG.Impl.Extensions.GenericExtensions.LexBIGServiceConvenienceMethodsImpl (the implementation of org.LexGrid.LexBIG.Extensions.Generic.LexBIGServiceConvenienceMethods) object.
3. The server then creates an org.LexGrid.LexBIG.cagrid.LexBIGCaGridServices.LexBIGServiceConvenienceMethods.service.globus.resource.LexBIGServiceConvenienceMethodsResource. This Resource will be used to hold the instance of org.LexGrid.LexBIG.Impl.Extensions.GenericExtensions.LexBIGServiceConvenienceMethodsImpl, the implementation of org.LexGrid.LexBIG.Extensions.Generic.LexBIGServiceConvenienceMethods that was created above.
4. The server returns an org.LexGrid.LexBIG.cagrid.LexBIGCaGridServicesLexBIGServiceConvenienceMethods.stubs.types.LexBIGServiceConvenienceMethodsReference object to the client. This is the reference to the LexBIGServiceConvenienceMethods Service Context. This object has a direct reference to the Resource created above. This LexBIGServiceConvenienceMethodsClient implements org.LexGrid.LexBIG.Extensions.Generic.LexBIGServiceConvenienceMethods. The user now uses this client to make transparent Grid calls through the Service Context. Because this LexBIGServiceConvenienceMethods implements org.LexGrid.LexBIG.Extensions.Generic.LexBIGServiceConvenienceMethods, API calls will look to the user as being identical to direct LexBIG API calls.
5. The client may continue to make statefull calls to the LexBIGServiceConvenienceMethods Client and the assigned Resource.
