....resources are stored procedures. These two models depend on the underlying system (file system or database server) and project its identifiers (directory and file names or procedure names) There are some approaches that concentrate on resource position modeling. The Structured Graph Format (SGF) [6] integrates the strict hierarchical (tree) organization with the free network model. A similar approach can be seen in the SiteBrain model [13] The resource composition is efficiently modeled with WebML [3] The specification of a site in WebML consists of four orthogonal perspectives that ....

....individual components is called the composition of the resource. Also, a component has its own identity, embedded in the identity context of the resource in which the component is placed. Resource s position in the Web site defines its relationships with other resources on that site (as in [2]) The principle of relating resources to concepts ties the resource position tightly to its identity relationship between resources is similar to relationships between represented concepts. 3. URIGRAPH This section gives a brief overview of the model based on the definition of Web site ....

....computer science student, communication student, etc. Obviously there may be several presentations for the same concept and a single page of the site may include several presentation elements. At the lowest level, the site itself is represented using the Structured Graph Format (SGF) vocabulary [9]. SGF is an XML compliant markup language based on structured graphs for capturing Web site structures. The students state description contains a static section supplying general information about the student such as name, major, email, and specific interests. This section is called static ....

....Such user defined tags on data elements can identify the semantics of data. The relationships between elements can be defined by nested structures and references. For example, XML metadata can be used to describe a web site structure to facilitate navigation by generating interactive site maps [19]. To retrieve XML and semi structured data, several query languages have been proposed. Examples are Lorel [1] XML QL [10] XML GL [5] Quilt [7] XPath [8] and XQuery [6] The XQuery is the first public working draft of a query language for XML released recently from the World Wide Web ....

....adm and XML will be described and it will be shown how our approach can be properly extended to the automatic generation of XML sites. Generated sites will be so: i) more easily suitable for declarative structured querying by navigational languages and advanced query systems (see for example [6, 16]) ii) self described, because the implicit knowledge contained in the logical scheme of the site can be made explicit into XML declarations and tags; and (iii) compliant with a recommended and widely accepted standard and then suitable for data exchange in cooperative applications. 2 The Araneus ....

....connection, it gets a link to the community of people using the awareness service. Somehow, the awareness client must be able to communicate with the browser, in order to capture the user s activities and to always know where the user is on the WWW (a method supporting this process is described in [42]) Note that the awareness client can be more or less tightly bound to the browser (Java applet, plug in, different application) Another solution for sharing state among a collection of Web browsers is to rely on HTTP proxies. When several users send their requests to the same proxy, then this ....

....in Figure 2 thus represents a site with many, but unhappy visitors. Figure 2. Abstract representation of user feedback In addition, the awareness framework integrates support for SGF metadata [44] SGF is an XML application used to describe the structure of Web sites with structured graphs [42]. It benefits to the awareness framework in two ways. Firstly, it provides a way to create explicit representations of Web activity. Indeed, SGF tools can visualize the structure of the monitored Web spaces. The sitemaps generated by this process can be annotated to represent activity. Figure 3 ....

....possibility to a user, that locating an item with an attribute search may only take order log n rather than order n steps. Our system supports web site and local file system searches. It requires that sitemap hierarchy information be present, in the form of a Structured Graph Format (SGF) file [6]. Integrating search results with sitemaps places greater demands on the user interface used for their delivery. The interface needs to be capable of providing overviews, clustering search results visually within this overview, and making the distribution of search results visible. In this paper ....

....including the Dublin Core and PICS. Site maps Metadata can describe properties about one particular resource, but it can also describe relationships between several resources. Machine understandable site maps are one application which uses this mechanism. With the Structured Graph Format (SGF) [3], for example, the structure of a Web site is described as the combination of a hierarchy and a network. SGF metadata can, for example, be used to dynamically generate site maps to support user navigation. Domain specific structured documents MathML 5 , SMIL 6 and XML EDI 7 are only some ....
