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 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. Install the supplied change set into the service. Update the metadata for a change set and return an image of the updated resource. Remove the <i>changeAble</i> resource from the service. Update the descriptive information of a change set. Create a new change set and set it in an OPEN state Validate the change set and report any errors or warnings that would occur were it to be applied. Update an existing <i>ValueSetCatalogEntry</i>Update an existing <i>ValueSetCatalogEntry</i> The <i>changeSetContext</i> is recognized by the service, but its state is not <i>OPEN</i>. The change set specified could either not be read or located by the service. The set of exceptions that can occur on updating any resource description Apply the proposed changes specified in the change set transaction to the changeable being updated. Create a new <i>ValueSetCatalogEntry</i>Create a new <i>ValueSetCatalogEntry</i> The <i>changeSetContext</i> is recognized by the service, but its state is not <i>OPEN</i>. The change set specified could either not be read or located by the service. The supplied value set URI already exists as an <i>about</i> or <i>alternateID</i> for a value set in the service. The supplied <i>valueSetName</i> already exists in the service. Return the change set referenced by the supplied URI. Cancel the proposed changes specified in a change set transaction to the changeable being updated. Return a change set with an iterator that allows its contents to be read in chunks. 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>. This is a helper function that is used in the creation and update of other resources and does \emph{not} change the state of the service. 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>. Note that this is a helper function and does not effect the state of the service. Services may choose to validate the input parameters of this method when it is invoked or may postpone validation until the corresponding create or update service call is invoked.
