E-Speak is an open-source software environment used to facilitate the development of electronic services over the Internet. Built on Extensible Markup Language (XML), E-Speak is associated with Microsoft's .NET initiative and was engineered to computerize human manual tasks via a platform that enables data exchange between computers.
E-Speak technology is similar to Common Object Request Broker Architecture (CORBA), Lightweight Directory Access Protocol (LDAP) and Web Service. Designed by Hewlett Packard (HP), E-Speak was discontinued in December 2002.
For example, planning a vacation usually involves online searches for the best airfare, hotel and rental vehicle services to accommodate financial and service criteria. E-Speak allows a traveler to send this criteria to a Web service provider agent, which locates individually matched service providers. An added value is that if a traveler must reschedule a flight or hotel reservation, service provider computers work behind the scenes to automatically update and change criteria data.
Although HP abandoned its intellectual property rights for E-Speak, it still uses E-Speak as a principal element in its product management module. HP also sells servers, storage and application solutions to programmers that use E-Speak on their websites.
