The Data Distribution API supports the following distributors. These can be used in combination in a configuration file to define an action, parameters, and response.
| Name | Description |
|---|---|
| HelloDistributor | The Hello World Demonstration |
| FileDistributor | Sends the contents of a file as an HTTP response |
| SelectingFileDistributor | Serves the contents of a file. Selects the file by extracting a value from the HTTP request, and using it to construct the file path. |
| SelectFromContentDistributor | Executes a SPARQL SELECT query against Vitro’s content triple-store, and returns the results in JSON format: application/sparql-results+json. |
| RdfGraphDistributor | Executes one or more GraphBuilder instances. Merges the results into an internal RDF graph, and returns that graph in Turtle format: text/turtle. |
| SelectFromGraphDistributor | Executes a SPARQL SELECT query against an internal RDF graph. The graph is created by merging the outputs of one or more GraphBuilder instances. The results are returned in JSON format: application/sparql-results+json. |
| EmptyGraphBuilder | Creates an RDF graph containing no triples. Used for tests, examples, or placeholders. |
| ConstructQueryGraphBuilder | Executes SPARQL CONSTRUCT query(s) against Vitro’s content triple-store, and returns a model that contains the (merged) results. |
| IteratingGraphBuilder | A GraphBuilder decorator that runs one or more “child” builders multiple times, each time providing a different value for a specified request parameter. The results of all queries are merged into a local RDF graph. |
| DrillDownGraphBuilder | A GraphBuilder decorator that runs one or more “child” builders multiple times, each time providing a different value for a specified request parameter. The results of all queries are merged into a local RDF graph. |
| JavaScriptTransformDistributor | A wrapper that uses a JavaScript function to transform the output of the wrapped distributor. |
