alist of the representation formats supported by the service. Example: text/html, text/xml, application/json the version or release identifier of the service the default format used by the service unless otherwise specified the set of namespaces recognized by this service. Because many namespace identifiers tend to be cryptic (i.e. HL7 OIDs, BioPortal URL's, etc.), <i>knownNamespace</i> includes the namespace name, an optional URI \emph{and} a place to provide textual detail describing what the namespace references. Note that namespace names must be unique across an entire CTS2 implementation - the same namespace name cannot represent one namespace in code system A and a second in code system B. Note also that namespace names are \emph{local} to a service instance. Information that is communicated between service instances, recorded in data tables or client software \emph{must} use full URIs. a reference to the individual or organization that provides the service. the set of service profiles that are supported by this service implementation a description of the service, its use, etc. a short name that identifies the particular service and implementation the particular implementation type(s) supported by this profile the set of structural profiles that the update service can apply changes to Update the descriptive information of a change set. Apply the proposed changes specified in the change set transaction to the changeable being updated. Update the metadata for a change set and return an image of the updated resource. Remove the <i>changeAble</i> resource from the service. Clone the <i>changeAble</i> resource. Cancel the proposed changes specified in a change set transaction to the changeable being updated. Return the change set referenced by the supplied URI. Validate the change set and report any errors or warnings that would occur were it to be applied. List the URIs of all the changes that were applied between <i>fromDate</i> and <i>toDate</i>. If <i>fromDate</i> is absent or is less than <i>toDate</i>, entries will be listed in forward chronological order, otherwise they will be listed in reverse order.

Create a new <i>Property</i> for inclusion in a resource or statement construct Create a new <i>StatementTarget</i> of type <i>RESOURCE</i>.

Note that URI's that reference classes, predicates or individuals should be created using the <i>newEntityReferenceTarget </i>method Create a new <i>StatementTarget</i> of type <i>LITERAL</i>. Note that this is a helper function and does not change the state of the service itself. Create a <i>StatementTarget</i> of type <i>ENTITY</i>.
