Specify internal location of a GXOS object. Absolute Garnet Address //RootName/Collection1/Collection2/ …. /CollectionN/node As RootNames unique, this is unique. Only used in Java implementation for actual program handle to Object. Optional Specification of one or more external locations where we might be able to find information to understand more about GXOS Specification of This TreeObject and its related quantities. Specify external location of information. URL File name on ExternalComputer DEVICEOBJECT Computer where information can be found. Defaults to current ClientDevice or ServerDevice if information parsed on Server. File || Directory Specify from users point of view destination queue for message; implicity uses internally a TopicObject DTD But DestinationObject inherits from TreeObject List of Entities for which one wishes to direct some information This can be explicit names or implicitly defined either a selector or by Topic of Publish/Subscribe system Unique ID of message including sequencing Information. This is discussed by Shrideep. For Garnet Message is uniquely specified by GXOS Handle in InternalND DTD of Stream and Sequence Number within Stream. Sequence Number of Event in this Stream (Node/ParentObject) Stream to which event belongs in full InternalND Syntax //GarnetRoot/B/C/ ../Streamitself This is ESSENTIAL information as uniquely determines VirtualEnvironment Sharedlet (collaborating application) and SourceDevice and EventUserObject String produced for JMSMessageID Specify time Time of an event: typically in number of milliseconds since Jan 1, 1970, 00:00:00, Universal Coordinated Time (GMT). Default TimeSyntax is above is GMTMillisecs. Other forms e.g. Mon, 19 Dec 1995 GMT are represented by TimeSyntax as GMTString. PSTString, EDTString etc. are other forms. Clock domain used in Time -- this is explained in separate memo. Typically this is either clock of source or the System Clock Domain defined for current MeetingContext. One just uses begin || end Defines action that Time refers to -- begin is default if property not defined. This is used by SMIL collections. Original clock if time converted to a particular standard. One just uses the GXOS Internal Name for Device whose clock is originally recorded time. Internal name for instance by WebExport and NodeProfile Related NodeContent's InternalName Placeholder for elements RealizationType, Resolution, RenderingOptimization, ExportDetails Container for related objects Placeholder for elements Specify reason for this Realization.

Also can use XSIL (Caktech Scientific Data Format) XML or JMS body types. See Content-Transfer-Encoding in MIME encoding. Byte streams of local realization Garnet XML based Object Specification Specify hierarchy of Collection(session), stream, events or basic hierarchial unit. Namespaces in GXOS provide means to name an object subtree and access it through its name. Objects in different namespaces can be named using the format nsname:object_name. Each namespace name is valid only for its children and subtrees. ParentObject in InternalND DTD of which current object is a child. Originally we allowed Multiple ParentObjects to support Multiple TreeContexts which in UNIX language are different Symbolic links. This has been replaced by NodeProfile mechanism. Name of this node within current hierarchy. If NodeRooting is Root, the NodeName must be unique so that all trees are uniquely identified. NodeType equals Event is same as NodeType equals GMS. NodeNames ParentMetaData and ParentFragment are containers for more information about parent node. Optional detailed type with a meaning specific to NodeType e.g. for NodeType equals Event, CustomType is MessageType. If NodeType is Collection then CustomType is either Mixed or NodeType of Contained Objects. Leaf || InternalNode || Root Version of schema used. Any number of free form comments Time at which Node last updated. Defaults to NodeStartTime Optional record of child objects (implied by GXOS child objects having NodeParent pointing to this object) Handle to child. Specify processing history with multiple ProcessingTimes and ProcessingDevices and ProcessingStatus. ProcessingContext defines part of Garnet that performed processing. Start time of this node in TimeObject DTD. Note that NodeStartTime and NodeEndTime can both a) be inherited from parents and b) depend on inheritance tree (i.e. TreeContext). So one could define NodeStartTime for a particular (Leaf) node and then NodeEndTime would depend on TreeContext with which this is used. End time of this node in TimeObject DTD. Container for GXOS or CustomExtensions Customize this node using strategy specified by content type and TreeContext and by data added by system. Profile includes elements TreeContext and CustomProfile. A Node used solely as a container need not have any contents although a NodeContent of Type = Summary and a NodeIcon are recommended. Defines accessibility rights of other objects i.e. processes, users, to this object. This uses ComputerObject DTD and is SourceObject for firststep. Status or action on event at this stage. Choose from Success || Failure || Replay || Originate || Acknowledge Any comment on why processing needed. Put into ProcessingTime TimeObject DTD time of processing including Time, CurrentClock, ReferenceAction. If ProcessingStatus is Originate, then use Node/NodeStartTime. Device where processing occured. If ProcessingStatus is Originate, then use SourceDevice. Context where processing occured. If ProcessingStatus is Originate, then use GMSStream. If needed ID of Update message spawning this processing. If absent, then an Internal Update Label (incremented by 1 starting at zero) of ProcessingStage to allow reference by AcknowledgeObject. IMS || ADL || Gateway Container for GXOS or CustomExtensions Hold parameters for undefined use. Extends CustomParameter with parameteruse attribute This defines nature of tree within which this node is located -- currently TreeContext is defined as a set of keyword tags. Specify the custom application and TreeContext specific parameters used by NodeProfile. Specify content in ObjectRealization DTD. Specify object thumbnail display icon in ObjectRealization DTD. Extends TreeObject to specify Server or Client side device or computer resource Obviously could be much richer Name.Domain is Computer Full Name IP Address Extends TreeObject for events in Stream. Default is Implicit or that GMSMessageMode implied by other Message properties; Update implies that Message is Getting or Setting properties of objects and Event has an UpdateExtension Has additional allowed values for particular MessageType's Specify list of destination objects using DestinationObject DTD Allows multiple destinations and implies DestinationQueue, DestinationTopic, DestinationSubTopic Used in cruder JMS Header specification of Destination Client or Server Computer that produced message with InternalND pointer to it as a DeviceObject Generates SourceName SourceDomain used in JMS This is not really necessary as implied by GMSStream and Information available from GXOS 0 (lowest) to 100 Highest) Collection (of messages) wrt to which Priority refers If message defines a MeetingContext, default value is GarnetRoot; if message is internal to a stream, default value is StreamName If message inside a MeetingContext but outside a stream, then PriorityScope is defaulted to MeetingContextName PriorityScope can reference any root or node of any tree containing this message -- see TreeObject DTD Idea is that subsystem setting Priority only has "visibility" a certain way up the tree from where it sits In particular, it may only know about the Sharedlet(Stream) or a little broader the MeetingContext from which message comes from The assumption is that "system" can apply a relative priority between different PriorityScope's The unique user NickName associated with this Event This is not really necessary as implied by GMSStream and Information available from GXOS Specifies in UserObject DTD the user at Source This is not really necessary as implied by GMSStream and Information available from GXOS Unique ID of message including sequencing Information. This is discussed by Shrideep.

It contains multiple policies for each service provided in the architecture. The type of the Object element is the same as the InternalND so that we can have control over every object accessable through GXOS links. Protocol element defines what type of communication protocol is used between user's or client application's site and the service specified in the SecurityObject's Context attribute. Values for Protocol could be S-HTTP, Kerberos V4, etc. A ProtocolType could be defined and set here. Context attribute defines the service the security policy will be used to access. It must be defined for each policy. Values for Context could be Grading System, TMD, or other services provided in the overall architecture. GXOS user class.
