....to rewrite queries for relaxation and restriction. Without modification, the method proposed in this paper is used not only for multimedia XML data collections but also for general XML databases. Keywords: XML Data Schema, Schema Levelization 1. INTRODUCTION EXtensible Markup Language (XML) [2] is a new standard for data representation and exchange on the Intemet. In the Internet, an XML element tagged text data is semistructured, that is, it is irregular in structure and is populated without rigid constraints. Data in XML on the Internet is usually very large in size and various in ....

....Schemas are then levelized with respect to the frequency of topological document structures in a database. The topological structural information of these schemas is used to formulate queries and to rewrite queries for relaxation and restriction. 1 Introduction EXtensible Markup Language (XML) [2] is a standard for data representation and exchange on the Internet. It is possible that multimedia data is represented and integrated in XML. In the Internet, an XML tagged text data, which is semistructured, is able to integrated with a multimedia data, which may be unstructured (e.g. Internet ....

....Input. At the bottom of the window is the user input area. This includes the scene advance checkbox, an input style pop up (that lets the user chose between saying, thinking, shouting, and doing) as well as the text input field. Technology Lead Line scripts are written in a tagged, XML format [2]. This approach makes it easy for authors to create and edit scripts using any familiar text editor. The format is also well known to anyone who has used HTML to create a web page. The format allows for open ended future extension of the script feature set. XML script tags are provided to define ....

....on the Internet, it is essential to develop methods for levelizing schemas for those heterogeneous information sources. 1.1 Problem Statement EXtensible Markup Language (XML) is an emerging standard for data representation and exchange on the Internet. Due to the inherent exibility of XML [3], semi structured information sources can be represented in XML. Even so, because of the co existence of semi structured data with un well structured data, 2 Jong P. Yoon et al. query formulation is not easy and ecient without knowing in advance the common structure of the data. The following is ....

....Section 4 describes schema extraction, and Section 5 describes a method of schema levelization. Section 6 describes integration of the levelized schemas. Finally, this paper concludes our accomplished work with future research work in Section 7. 2 Related Work With the recent emergence of XML [3], a proposed standard for exchanging information on the Web [11] and the remarkable similarity of XML to typical models for semi structured data, support for query languages for semi structured data and the performance of such queries over large semi structured databases is of increasing ....

....and the DTDs used to constrain XML data, and describes metadata management using RDF. It also discusses how XML data is queried, referenced, and transformed using stylesheet language XSLT and referencing mechanisms XPath and XPointer. 1 Describing XML Data The Extensible Markup Language (XML) BPSM98] models data as a tree of elements that contain character data and have attributes composed of name value pairs. For example, here is an XML representation of catalog information for a book: book title The spy who came in from the cold title author John lastname Le ....

This application is described in [Bra98] Addressing parts of XML documents is also important when transforming XML using XSLT and XPath as described above. However, the addressing capabilities of XPath are not sufficient. For example, the above application may wish to ....

....XML concepts. Although technically not required, XML documents should begin with an XML declaration, similar to the one on the first line of our example, identifying the version of XML used. Element and attribute names appearing in an XML document may be qualified using XML namespace declarations [BHL99] such as those on lines 3 4 above. Our example introduces two namespaces. The first is identified using the URI http: w3.org TR 1999 PR rdf syntax# and is assigned a shorthand rdf. This namespace contains the elements and attributes defined in [LS99] The second is an imaginary books schema ....

....The core features of WebDAV are [23, 9] ffl Metadata management. Metadata (Properties) denote the information associated with Web resources, such as the title, creator, etc. A property is a name value pair, where the name is a URL, and the value is a sequence of well formed XML elements [3]. The protocol offers the ability to create, remove, and query properties by using the new methods PROPPATCH and PROPFIND. ffl Name space management. WebDAV defines two new methods COPY and MOVE to instruct the server to copy, move, or delete Web resources. Deleting a resource is already provided ....

....applications should support the HTTP Digest Authentication scheme [7] WebDAV extends HTTP 1.1 by new methods that require certain parameters. In HTTP 1.1 the parameters for methods are exclusively encoded in the HTTP header fields. Unlike HTTP 1. 1, some WebDAV method parameters are encoded as XML [3] request bodies. These parameters are mostly application specific and must be provided by the user. Therefore, the use of WebDAV requires either new Web clients or extensions of existing Web browsers which support the additional functionality. In this paper we present an extension of an existing ....

Logical hypertext documents As mentioned above this work focuses on access control in Inter Intranet based hypertext systems using XML. XML [4] is a recommendation of the W3 Consortium and is regarded as a likely successor of HTML [22] In a hypertext system a logically closed document is built from several physical units. We distinguish here between a physical document and a logical document. The physical document structure is simply ....
