). The XML Enabled Directory (XED) framework leverages existing Lightweight Directory Access Protocol (LDAP) and X.500 directory technology to create a directory service that stores, manages and transmits Extensible Markup Language (XML) format data, while maintaining interoperability with LDAP clients, X.500 Directory User Agents (DUAs), and X.500 Directory System Agents (DSAs). The main features of XED are: * semantically equivalent XML renditions of existing directory protocols, * XML renditions of directory data, * the ability to accept at run time, user defined attribute syntaxes specified in a variety of XML schema languages, * the ability to perform filter matching on the parts of XML format attribute values. * the flexibility for implementors to develop XED clients using only their favoured XML schema language. The XML Enabled Directory allows directory entries to contain XML formatted data as attribute values. Furthermore, the attribute syntax can be specified in any one of a variety of XML schema languages that the directory understands. The directory server is then able to perform data validation and semantically meaningful matching of XML documents, or their parts, on behalf of client applications, making the implementation of XML-based applications easier and faster. XML applications can also exploit the directory's traditional capabilities of cross-application data sharing, data distribution, data replication, user authentication and user access control, further lowering the cost of building new XML applications XED Implementations {{Proper name, eNitiatives' ViewDS Discovery Server provides organisations with a fast, scalable and flexible directory system. As it has been developed strictly adhering to open standards and it features support for the X.500, LDAP, XED and ACP133 standards. Being standards compliant, ViewDS will interface with a variety of applications, both now and into the future. Internet protocols XML Computer-related introductions in 2003
