Class sswap:Resource (Developer docs). A required class. This class designates the semantically described resource. Resources that "do things", for example, transform input (sswap:Subject) to output (sswap:Object), are commonly called services. Resources may also be web pages, ontologies, etc. Resource description graphs reside at distinct URLs, one for each resource.

 

Its Properties

sswap:name                            Required property that points to a string containing the resource's preferred name.

sswap:operatesOn                   Required property that points to a web resource of type sswap:Graph. That resource is often a blank node (no URL). Resources can have more than one sswap:operatesOn. OWL DL does not allow the use of RDF Containers and Collections. By using the sswap:Graph class you can build complex data structures while remaining OWL DL compliant. This allows you, for example, to differentiate between accepting and returning data as a pair of lists or a list of pairs.

sswap:aboutURI                     Optional reference to web page where the user could find additional information about the provider.

sswap:inputURI                      Optional reference to web page where the resource can solicit input from a user. For machine-machine interaction, this user input page is not needed. But if you want search engines to be able to find your resource and then forward users to a web page for them to input data and parameters before invoking the resource, use this predicate to indicate the URL of that web page. See also sswap:outputURI below.

sswap:metadata                       Optional reference to URL where the provider can place text that may be used by a semantically-aware search engine to richen the association of words with the resource. It could be words about the resource, or, for example, it could be a list of genes that the provider wants associated with it to empower token-matching search engines. The provider has no control as to how, or if at all, these words are used by third-party engines.

sswap:oneLineDescription     Optional reference that points to a string containing a brief description of the provider. Should be human readable for use by search engine result pages.

sswap:outputURI                    Optional reference to web page which can format the SSWAP output graph of the resource to make it suitble for an end-user. For machine-machine interaction, this output page is not needed. But if you want users to be able to read the output as a human readable web page, instead OWL RDF/XML, then use this predicate to indicate the URL of that web page. See also sswap:inputURI above.

sswap:providedBy                  Optional property pointing to the provider offering this resource. Resources can have at most one sswap:providedBy predicate. Providers must either explicitly reciprocate the relationship by using a sswap:providesResource predicate or their URI must be a parent of the Resource's path; e.g., sswap.info/examples/resourceProvider and http://sswap.info/examples/resources/canonical/canonicalResource. If canonicalResource would claim to be provided by www.YourWebsite.org/yourProvider, yourProvider would have to reciprocate the relationship by using the sswap:providesResource predicate pointing back to canonicalResource. See also sswap:Provider on the Provider page.
