The new public review draft of the document "ebXML Registry Profile for Web Ontology Language (OWL) Version 1.5" has been released. Being produced by the OASIS ebXML Registry Semantic Content Management Subcommittee, it defines a new version of the ebXML profile used for publishing, management, discovery and reuse of the ontologies developed by the OWL Lite standards.
This document tries to define the normative ebXML Registry Profile for the OWL (Web Ontology Language) Lite. It has the purpose to normatively specify how the OWL Lite constructs are
XML is a markup language for structured documentation. Structured documents are documents that contain both content (words, pictures, etc.) and some indication of what role that content plays (for example, content in a section heading has a different meaning from content in a footnote, which means something different than content in a figure caption, etc.). Almost all documents have some structure.
A markup language is a mechanism to identify structures in a document. The XML specification defines a standard way of adding markup to documents.

Annotation is the process of associating metadata with data. This article presents a Web services API intended as an industry standard for client-server systems designed to facilitate the structured annotation of heterogeneous data. The author presents the goals of the Annotation Web services API and then discusses how those goals motivate the data model around which the API operates. The author also discusses 29 methods that comprise the API including two examples of possible sequences of API calls to create and retrieve annotations.

OASIS announced the publication of a public review draft for the "ebXML Registry Profile for Web Ontology Language (OWL) Version 1.5" specification, ending 11-February-2007. Produced by members of the OASIS ebXML Registry Semantic Content Management Subcommittee, this document defines the ebXML Registry profile for publishing, management, discovery, and reuse of OWL Lite Ontologies.
The SC was chartered to define use cases and requirements for managing semantic content within the ebXML Registry 4.0, seeking to establish a formal liaison with relevant
DataBinding is core to XPComponents, all components directly support data binding, no classes to include, nothing to enable, its all there built in from the ground up.
The XP Components provide a powerful feature rich DataBinding architecture
Data binding in its traditional sense means associating some underlying data with one or more user interface elements. The data provides the information to display. The user interface elements render the information in the appropriate format.
The XP Data Architecture extends the traditional idea of data

Before we start talking about XML and databases, we need to answer a question that occurs to many people: "Is XML a database?"
An XML document is a database only in the strictest sense of the term. That is, it is a collection of data. In many ways, this makes it no different from any other file -- after all, all files contain data of some sort. As a "database" format, XML has some advantages. For example, it is self-describing (the markup describes the structure and type names of the data, although not the semantics), it is portable (Unicode), and it
XLink Elements and Attributes
XLink offers two kinds of links:
Extended links
Extended links offer full XLink functionality, such as inbound and third-party arcs, as well as links that have arbitrary numbers of participating resources. As a result, their structure can be fairly complex, including elements for pointing to remote resources, elements for containing local resources, elements for specifying arc traversal rules, and elements for specifying human-readable resource and arc titles.
XLink defines a way to give an extended link special

In order to appreciate XML, it is important to understand why it was created. XML was created so that richly structured documents could be used over the web. The only viable alternatives, HTML and SGML, are not practical for this purpose.
HTML, as we've already discussed, comes bound with a set of semantics and does not provide arbitrary structure.
SGML provides arbitrary structure, but is too difficult to implement just for a web browser. Full SGML systems solve large, complex problems that
This document specifies XML syntax and processing rules for creating and representing digital signatures. XML Signatures can be appliedto any digital content (data object), including XML. An XML Signature may be applied to the content of one or more resources.Enveloped or enveloping signatures are over data within the same XML document as the signature; detached signatures are over data external to the signature element. More specifically, this specification defines an XML signature element type and an XML signature application; conformance requirements
This specification defines the XML Pointer Language (XPointer), the language to be used as the basis for a fragment identifier for any URI reference that locates a resource whose Internet media type is one of text/xml, application/xml, text/xml-external-parsed-entity, or application/xml-external-parsed-entity [IETF RFC 2376]. This specification does not constrain the syntax or semantics of URI references to resources of other media types, although it provides extension facilities that may be used with other types.
XPointer supports addressing into
