The Dublin Core Metadata Initiative is an open organization engaged
in the development of interoperable online metadata standards that support a broad range of purposes and business models. Its most important standard is the Dublin Core Metadata Element Set [1], a vocabulary of fifteen properties for use in resource description, which was approved as ISO 15836:2003 [2]. This and other vocabularies developed by Dublin Core are defined as abstract models which may be expressed in any number of different syntaxes. This paper presents a proposal for expressing such metadata using Topic Maps.

Topic Maps is an international standard technology for describing knowledge structures and using them to improve the findability of information. It is based on a formal model that subsumes those of traditional finding aids such as indexes, glossaries, and thesauri, and extends them to cater for the additional complexities of digital information. Topic Maps is increasingly used in enterprise information integration, knowledge management, e-learning, and digital libraries, and as the foundation for Web-based information delivery solutions. This entry provides a comprehensive treatment of the core concepts, as well as describing the background and current status of the standard and its relationship to traditional knowledge organization techniques.

The extreme generality of XML makes it a very thin platform. Data oriented XML documents share some commonalities which allow us to enrich the platform. The Resource Description Framework provides a number of features on top of XML to facilitate the representation of data. In this proposal we enrich XML by adding two important features from RDF for use in all XML documents: object identity and explicit relations. The interaction between these two features allows us to specify such relations not just between objects in a single document, but also between objects on different sites, thereby enabling an "XML Web"

While Sig.ma is by no mean the first data aggregator for the Semantic Web, its contribution is to show that the sum is really bigger than the single parts and exciting possibilities lie in a holistic approach for automatic semistructured data discovery and consolidation.

In Sig.ma, elements such as large scale semantic web indexing, logic reasoning, data aggregation heuristics, pragmatic ontology alignments and, last but not least, user interaction and refinement, all play together to provide entity descriptions which become live, embeddable data mash ups.

Embeddeding meta-information in XHTML documents via RDFa in XHTML: Syntax and Processing is an excellent way to ensure that more semantic information is available in documents with very little authoring overhead. This document extends that significant advantage beyond XML / XHTML into traditional HTML-based documents. Since HTML is by far the most prevalent grammar for web pages, enabling their easy annotation will dramatically increase the penetration of semantic information throughout the web.

NeOn is a 14.7 million Euros project involving 14 European partners and co-funded by the European Commission’s Sixth Framework Programme under grant number IST-2005-027595. NeOn started in March 2006 and has a duration of 4 years. Our aim is to advance the state of the art in using ontologies for large-scale semantic applications in the distributed organizations. Particularly, we aim at improving the capability to handle multiple networked ontologies that exist in a particular context, are created collaboratively, and might be highly dynamic and constantly evolving.

In the NoTube project, we are exploring the use of Semantic Web technology in Television and Web-TV scenarios. By making use of richer and linked descriptions of content and users, we hope to help users better find (and annotate, tag, cross-link etc.) content that is interesting to them. The growing amount of linked RDF data out there in the public Web provides a useful background dataset; for example we can use SKOS thesauri or DBpedia to indicate content topics or user interests.

Web IDs are world-wide "strong identifiers" that you and your software can use to precisely identify and distinguish concepts, even if they share the same names.

For example: "Jaguar" can be used to refer to several distinct concepts (the animal, the car company, the musical artist, etc.) but each of them have different Web IDs.

Whereas keywords are ambiguous, Web IDs are precise.

The Web of Data has many equivalent URIs. This service helps you to find co-references between different data sets. [...] if you provide a URI, it will give you back URIs that may well be co-referent, should any be known to it. In addition, by using sindice.com, if you search for a string, it will provide bundles of URIs that correspond to looking up that string at Sindice and processing them at <sameAs>.

Our goal is to design and implement D-FOAF, a distributed authentication and trust infrastructure without a centralised authority. D-FOAF will be a backbone for trust applications based on social relationships and will establish idenity of users similar to the way we establish identity and trust in real life. D-FOAF will be based on previous work like the P2P HyperCuP topology and FOAFRealm, a Semantic Web based user and relationship management system. Implementation work will be conducted for the J2EE, .NET and PHP environments.

Everyone on the Internet knows the buzzword social networking. Social networking services (SNS) usually offer the same basic functionalities: network of friends listings, person surfing, private messaging etc. With such features, SNSs demonstrate how the Internet continues to better connect people for various social and professional purposes. The fundamental problems with today's SNSs block their potential to access the full range of available content and networked people online. A possible solution is to build semantic social networking into the fabric of the next-generation Internet itself-interconnecting both content and people in meaningful ways. The semantic Web is a useful platform for linking and for performing operations on diverse person-and object-related data gathered from heterogeneous social networking sites. In the other direction, object-centered networks can serve as rich data sources for semantic Web applications.

The SIOC initiative (Semantically-Interlinked Online Communities) aims to enable the integration of online community information. SIOC provides a Semantic Web ontology for representing rich data from the Social Web in RDF. It has recently achieved significant adoption through its usage in a variety of commercial and open-source software applications, and is commonly used in conjunction with the FOAF vocabulary for expressing personal profile and social networking information. By becoming a standard way for expressing user-generated content from such sites, SIOC enables new kinds of usage scenarios for online community site data, and allows innovative semantic applications to be built on top of the existing Social Web.

This tutorial will give an overview of current proposals in the Semantic Web area for adding semantics to emerging Web 2.0 applications and established communications media such as blogging, wikis, and bulletin boards. We will also cover the usage of Semantic Web technologies for community portals. We will discuss current standardisation activities as well as research prototypes. Additional topics to be covered include semantic search based on metadata and large scale data integration as well as semantics in digital libraries. Finally, we will discuss and present current approaches to realise the ideas of Vannevar Bush and Doug Engelbart on distributed collaboration infrastructures, which we term Social Semantic Information Spaces.

After a short overview of both the Social Web and the Semantic Web, Breslin et al. describe some popular social media and social networking applications, list their strengths and limitations, and describe some applications of Semantic Web technology to address their current shortcomings by enhancing them with semantics. Across these social websites, they demonstrate a twofold approach for interconnecting the islands that are social websites with semantic technologies, and for powering semantic applications with rich community-created content. They conclude with observations on how the application of Semantic Web technologies to the Social Web is leading towards the "Social Semantic Web" (sometimes also called "Web 3.0"), forming a network of interlinked and semantically-rich content and knowledge.
