Developing Semantic Web Services is "well-informed about work on WS
[Web Services] and the SemWeb [Semantic Web], and in particular . .
. understand[s] OWL-S . . . very well . . .. Also, the book . . .
fill[s] a need that, to my knowledge, hasn't been met at all."
---David Martin, editor OWL-S Coalition The inventor of the World
Wide Web, Tim Berners-Lee, is also the originator of the next
generation Web architecture, the Semantic Web. Currently, his World
Wide Web consortium (W3C) team works to develop, extend, and
standardize the Web's markup languages and tools. The objective of
the Semantic Web Architecture is to provide a knowledge
representation of linked data in order to allow machine processing
on a global scale. The W3C has developed a new generation of open
standard markup languages which are now poised to unleash the
power, flexibility, and above all---logic---of the next generation
Web, as well as open the door to the next generation of Web
Services. There are many ways in which the two areas of Web
Services and the Semantic Web could interact to lead to the further
development of Semantic Web Services. Berners-Lee has suggested
that both of these technologies would benefit from integration that
would combine the Semantic Web's meaningful content with Web
Services' business logic. Areas such as UDDI and WSDL are ideally
suited to be implemented using Semantic Web technology. In
addition, SOAP could use RDF payloads, remote RDF query and
updates, and interact with Semantic Web business rules engines,
thereby laying the foundation for Semantic Web Services. This book
presents the complete Language Pyramid of Web markup languages,
including Resource Description Framework (RDF), Web Ontology
Language (OWL) and OWL-Services (OWL-S) along with examples and
software demos. The source code for the "Semantic Web Author," an
Integrated Development Environment for Semantic Markup Languages is
available on CD-ROM with the book.
As the last star fighter in squadron 111, Midshipman Henry Gallant
is on his way from Jupiter to Mars. With the United Planets' fleet
on the verge of annihilation, he can expect no help as he passes
through the asteroid belt and threatening aliens. With so much
uncertainty about the aliens' capabilities and intentions,
analyzing the captured computer equipment in Gallant's possession
could prove crucial. The fate of Earth could rest on the abilities
of Midshipman Henry Gallant. Unfortunately, it is his abilities
that have been much in doubt during his tour of duty. In an era of
genetic engineering, he is the only Natural (non-genetically
enhanced) officer left in the fleet. His classmates and superior
officers have all expressed their concern that he will not be up to
the demands of the space service. Only bright and attractive junior
officer Kelsey Mitchel has shown any sympathy for him. Now as his
navigator on the last fighter in squadron 111, her life as well as
a good many others, depends of Henry Gallant.
