The promise of the Semantic Web to provide a universal medium to exchange data information and knowledge has been well publicized. There are many sources too for basic information on the extensions to the WWW that permit content to be expressed in natural language yet used by software agents to easily find, share and integrate information. Until now individuals engaged in creating ontologies-- formal descriptions of the concepts, terms, and relationships within a given knowledge domain-- have had no sources beyond the technical standards documents.

The promise of the Semantic Web to provide a universal medium to exchange data information and knowledge has been well publicized. There are many sources too for basic information on the extensions to the WWW that permit content to be expressed in natural language yet used by software agents to easily find, share and integrate information. Until now individuals engaged in creating ontologies-- formal descriptions of the concepts, terms, and relationships within a given knowledge domain-- have had no sources beyond the technical standards documents. Semantic Web for the Working Ontologist transforms this information into the practical knowledge that programmers and subject domain experts need. Authors Allemang and Hendler begin with solutions to the basic problems, but don't stop there: they demonstrate how to develop your own solutions to problems of increasing complexity and ensure that your skills will keep pace with the continued evolution of the Semantic Web. . Provides practical information for all programmers and subject matter experts engaged in modeling data to fit the requirements of the Semantic Web. . De-emphasizes algorithms and proofs, focusing instead on real-world problems, creative solutions, and highly illustrative examples. . Presents detailed, ready-to-apply "recipes" for use in many specific situations. . Shows how to create new recipes from RDF, RDFS, and OWL constructs.

The Semantic Web treats data as a distributed resource on the scale of the World Wide Web, and incorporates features to address the challenges of massive data distribution as part of its basic design. The aim of the first two editions was to motivate the Semantic Web technology stack from end-to-end; to describe not only what the Semantic Web standards are and how they work, but also what their goals are and why they were designed as they are. It tells a coherent story from beginning to end of how the standards work to manage a world-wide distributed web of knowledge in a meaningful way. The third edition builds on this foundation to bring Semantic Web practice to enterprise. Fabien Gandon joins Dean Allemang and Jim Hendler, bringing with him years of experience in global linked data, to open up the story to a modern view of global linked data. While the overall story is the same, the examples have been brought up to date and applied in a modern setting, where enterprise and global data come together as a living, linked network of data. Also included with the third edition, all of the data sets and queries are available online for study and experimentation at data.world/swwo.

Evolve or perish  - this is the motto for living systems. Judging by this saying, the Web is alive and well: new sites and business ideas are coming online almost daily and are able to attract millions of users often. The more recently coined term Web 2.0  summarizes many of the new developments, capturing efforts making the Web more interactive (like Ajax), more collaborative (like Wikis), or more relationship oriented (like online social networks), aiming to partially fulfill the original promise of the Web. These new Web developments offer an opportunity and challenge for the Semantic Web: what previously manifested itself mostly in dry  specifications is now becoming the foundation for information exchange on the Web, creating a shared semantic information space. These and other challenges have been picked up by several hundred computer scientists, developers, vendors, government workers, venture capitalists, students, and users, gathered in Athens, Atlanta, USA, November 5-9, 2006, for the Fifth International Semantic Web Conference (ISWC 2006). Building on previous successful meetings in Sardinia, Sanibel Island, Hiroshima, and Galway, this sixth annual conference demonstrates new research results, technology, and applications that show current incarnations of the Semantic Web. Especially encouraging is the shift towards more applications whereas the Research Track attracted roughly as many papers as in the previous year, the contributions submitted to the In-Use Track doubled.

TheWorld-WideWeb continues to growand newtechnologies,modes ofinter- tions, and applications are being developed. Building on this growth, Semantic Web technologies aim at providing a shared semantic information space, cha- ing qualitatively our experiences on the Web. As Semantic Web technologies mature and permeate more and more application areas, new research challenges are coming to the fore and some unsolved ones are becoming more acute. These issues include creating and managing Semantic Web content, making Sem- tic Web applications robust and scalable, organizing and integrating infor- tion from di?erent sources for novel uses, making semantics explicit in order to improve our overallexperience with information technologies, and thus enabling us to use the wealth of information that is currently available in digital form for addressing our everyday tasks. These and other challenges brought several hundred of researchers, devel- ers,governmentworkers,venturecapitalists,students,anduserstoBusan,Korea fortheSixthInternationalSemanticWebConferencewhichwasheldjointlywith the 2nd Asian Semantic Web Conference (ISWC 2007 + ASWC 2007). We are excited to o?er this volume with the main proceedings of ISWC 2007 + ASWC 2007 to the growingcommunity of researchersand practitioners of the Semantic Web. The tremendous response to our Call for Papers from a truly international community of researchers and practitioners from 30 countries, the careful nature of the review process, and the breadth and scope of the papers ?nally selected for inclusion in this volume all speak to the quality of the c- ference and to the contributions made by the papers in these proceedings.
