svn commit: r421341 -
/webservices/muse/trunk/modules/muse-wsrf/src-impl/org/apache/muse/ws/resource/metadata/impl/
Author: danj
Date: Wed Jul 12 10:37:15 2006
New Revision: 421341
URL: http://svn.apache.org/viewvc?rev=421341&view=rev
Log:
Updated these classes to reflect changes between WSRMD 2004 draft and WSRMD CD 01. Also added
two new classes to represent the new "metadata resource" concept that is present in CD 01; one
is the capability that exposes and EPR to the metadata resource, the other is for the metadata
resource itself.
Added:
webservices/muse/trunk/modules/muse-wsrf/src-impl/org/apache/muse/ws/resource/metadata/impl/SimpleMetadataResource.java

+NoPropertyName = There is a wsrmd:Property in the RMD that has no 'name' attribute. This attribute is required to map the property to one defined in the WS-ResourceProperties schema; the attribute value should be the qualified name of one of those properties.
ConstantButNotReadOnly = The wsrmd:Property with path 'XXX' is constant but not read-only - this is impossible. If a value is constant, it cannot be written to, so the modifiability of the property must be read-only.
InvalidModifiability = The wsrmd:Property with the path 'XXX' has an invalid modifiability attribute value: XXX. The accepted modifiability values are 'read-only' and 'read-write'.
InvalidMutability = The wsrmd:Property with the path 'XXX' has an invalid mutability attribute value: XXX. The accepted mutability values are 'constant', 'appendable', and 'mutable'.

NullMetadataDescriptor = The MetadataDescriptor is null.
EmptyTargetNS = The target namespace string passed to setTargetNamespace() is null or empty. Make sure that the target namespace is a valid URI string and is defined in the root element of the RMD.
NullDescriptorElement = The DOM Element with the MetadataDescriptor definition is null.
-NoDescriptorName = There is a wsrmd:MetadataDescriptor in the RMD that has no name attribute. This attribute is an xsd:NCName that uniquely identifies the descriptor.
+NoDescriptorName = There is a wsrmd:MetadataDescriptor in the RMD that has no 'name' attribute. This attribute is an xsd:NCName that uniquely identifies the descriptor.
+NoDescriptorInterface = There is a wsrmd:MetadataDescriptor in the RMD that has no 'interface' attribute. This attribute is an xsd:QName that links back to the WSDL portType.
+NoDescriptorWSDLLocation = There is a wsrmd:MetadataDescriptor in the RMD that has no 'wsdlLocation' attribute. This attribute is a set of two xsd:anyURI that contains the WSDL target namespace and WSDL location (path), separated by a space.
+InvalidWSDLLocation = There is a wsrmd:MetadataDescriptor in the RMD that has an invalid 'wsdlLocation' attribute. This attribute should be a set of two xsd:anyURI that contains the WSDL target namespace and WSDL location (path), separated by a space. The value you provided was 'XXX'.
UndefinedProperty = There is no wsrmd:Property defined with the path 'XXX'. You cannot read metadata for a property that does not exist. Use the hasProperty method to determine if a property name is valid.
NullPropertyMetadata = The PropertyMetadata reference is null.
NoExternalChanges = The property 'XXX' is not writeable by remote clients. Its value may change over the lifetime of the resource, but it may only be modified by internal components.
+IncompleteMetadataAttributes = The resource's WSDL does not have complete WS-RMD attributes in its portType, so Muse cannot tell if an RMD is meant to be applied or not. To fix this situation, make sure the portType references both the wsrmd:Descriptor and the wsrmd:DescriptorLocation attributes, or none at all.
+DescriptorNotFound = The RMD file XXX does not have a MetadataDescriptor whose 'name' attribute is 'XXX'.
+NoMetadataResource = There is no resource that implements the WS-RF MetadataResource capability defined in muse.xml. In order to use and read from a metadata resource, an application must expose a resource with the capability org.apache.muse.ws.resource.metadata.MetadataResource; this resource will represent the metadata descriptor for the resource.
+FoundMetadataResource = Successfully found the MetadataResource endpoint at 'XXX'. All metadata resources will be managed by this endpoint.
