Installation

Description

Write SADI Services in Ruby, then host them as a Sinatra server

Currently only supports [synchronous] service have been implemented.

Usage

To test the server, use the gem's executable sadi-rb. This will start the server on http://localhost:4567, and load the demo service.

The server can also be run as part of a script using

require 'sadi-rb'

SADI::Server.run!

Writing your own services

To create an asynchronous service, simply extend the SADI::SynchronousService module and implement the interface methods it requires;

require 'sadi-rb'

Class MyService
    def service_name
        "my_service_name"
    end

    def service_description
        # an RDF::Graph of your service's description
    end

    def service_owl
        # an RDF::Graph of your service's OWL classes
    end

    def process_object(input_graph, owl_object)
        # Service logic goes here

        # Should return an RDF::Graph of
        #   the output for the resource specified by the URI owl_object,
        #   from the RDF::Graph input_graph
    end
end

Although SADI can theoretically use any vocabulary for its service description, the gem internals currently require that you use the mygrid ontology in implementing your service_description method
