The MOF and GXL [16] do not support class extensions, i.e. the ability to add attributes to existing classes. CDIF [4] and RDF [38] both allow this kind of extension. 8. Incremental Loading Axis Incremental loading of information is about the ability to load new entities or additional information for entities that already exist in a model. The reasons for considering incremental loading are resource optimization and the ....

....such as CORBA implementations and Jini rely primarily on class or interface type to locate remote objects. We have developed an approach where service information can be represented in a more descriptive fashion. These descriptions are represented using the Resource Description Framework [42] and are encoded in XML (the eXtensible Markup Language) 41] This approach allows for a much richer set of information to be provided regarding the service. This information becomes available for searching when the service registers on the network. The approach o#ers many advantages over service ....

....an ACL and a content language to a set of Java classes representing the concepts in these languages. In addition, Resource Description Framework (RDF) schemas [21] corresponding to the languages are produced and the Java classes include code to marshal and unmarshal messages to and from an RDF [23] representation (serialised using the RDF XML syntax) This technique also allows descriptions of domain objects that are instances of an ontology expressed in UML to be marshalled and sent by value within the content of messages, however a discussion of the application of this idea is beyond the ....
....inheritance does not correspond well to inheritance in objectoriented models. For the marshalling framework described in this paper it was decided that mapping class diagrams to RDF schema specifications would be a simpler approach than using XML schema. The Resource Description Framework (RDF) [23] is a simple entity attribute value model designed for expressing metadata about resources. The RDF Schema is a set of predefined resources (entities with uniform resource identifiers) and relationships between them that define a simple meta model, including concepts of classes, properties, ....

....The properties of various context factors are already subject of standardization efforts. W3C is working on a framework for the management of device profile information called Composite Capabilities Preference Profiles [53] which is based on the Resource Description Framework (RDF) [54]. It specifies how client devices express their capabilities and preferences to the web application server. It defines recommendations about the content of such profiles but it is also extensible. New properties can be defined and included in the description and users can overwrite vendor defined ....

....of a DTD. While using DTDs as a primary way to reference classes of documents, we do not discard other methods. In particular, our model also supports the use of wild cards in the speci cation of document URIs and the possibilityofreferencing and evaluating meta properties, such as RDF markup [19]. The use of wildcards allows the speci cation of authorizations that apply to all documents matching a given path expression, depending on the le system organization. The reference to meta properties allows the speci cation of authorizations that apply to all documents satisfying speci c ....

....just for display purposes, but for using it in various applications. This Semantic Web can be achieved by adding semantic structures to the current Web. Many candidate techniques were proposed, such as semantic networks [16] conceptual graphs [5] the W3C Resource Description Framework (RDF) [14] and XML Topic Maps [11] Semantic networks are basically directed graphs (networks) consisting of vertices linked by edges. Edges express semantic relationships between the vertices. The conceptual graphs theory developed by Sowa [10] is a language for knowledge representation based on ....

....Web. XML is a first level of semantics which allows users to structure data with regard to their content rather than their presentation. However, more semantics can be added with the Resource Description Framework (RDF) or Topic Maps standards. RDF was developed by the World Wide Web Consortium [14] whereas Topic Maps were defined by the International Organisation for Standardization [4] The Topic Map paradigm was recently adapted to the Web by the TopicMaps.Org consortium [13] Both RDF and Topic Maps aim at representing knowledge about information resources by annotating them; these ....
