Simple Semantic Web Architecture and Protocol

Graph Search

This page describes an HTTP interface for searching for resources in the discovery server's repository. Also on this page is a simple HTML form for accessing the interface in order to search for SSWAP resources.

HTTP Interface

The URL for searching the repository for SSWAP resources is http://sswap.info/graph-search , accessible via an HTTP POST. It takes the following parameters:

Parameter	Required?	Description
query-graph	Yes	An OWL graph, in RDF/XML format, that serves as a template for resources to be matched.
statements	No	Indicates which statements should be returned for each matching resource. A value of `minimal` indicates that only a small amount of information (name, one line description, URL) should be returned for each resource; `query` indicates that only the statements in the query graph should be returned; `reachable` indicates that only statements whose subjects are subsumed by the URL of the resource should be returned (e.g. if a resource's URL is `http://www.foo.org/someResource`, then only statements whose subject's URL starts with `http://www.foo.org/someResource` should be returned. The default value is `reachable`.

Resource Search Form

The following form can be used to search this site's repository for SSWAP resources that match a query graph. The text area is initially prepopulated with an example graph that will show all resources. Type or paste a graph, in RDF/XML format, into the area below and press the "Search" button:
