C Semantic Web Activity The Semantic Web is a web of data. There is lots of data we all use every day, and it is not part of the web. I can see my bank statements on the web, and my photographs, and I can see my appointments in a calendar.

opds-spec.org | Open Publishing Distribution System Validate your OPDS feeds online Benoît Larroque (from Feedbooks) recently released a major update for his OPDS validator: This is a major step forward for the OPDS ecosystem since this validator not only includes the Relax NG validation that was previously released, but also check various requirements extracted from the 1.1 specification. I highly recommend anyone with an OPDS catalog in production or in development to check their feeds with the validator to ensure their full compliance with the OPDS 1.1 specification.

Web Ontology Language OWL / W3C Semantic Web Activity

Web Ontology Language OWL / W3C Semantic Web Activity

Overview The W3C Web Ontology Language (OWL) is a Semantic Web language designed to represent rich and complex knowledge about things, groups of things, and relations between things. OWL is a computational logic-based language such that knowledge expressed in OWL can be exploited by computer programs, e.g., to verify the consistency of that knowledge or to make implicit knowledge explicit.
RDF - Semantic Web Standards

RDF - Semantic Web Standards

Overview RDF is a standard model for data interchange on the Web. RDF has features that facilitate data merging even if the underlying schemas differ, and it specifically supports the evolution of schemas over time without requiring all the data consumers to be changed. RDF extends the linking structure of the Web to use URIs to name the relationship between things as well as the two ends of the link (this is usually referred to as a “triple”). Using this simple model, it allows structured and semi-structured data to be mixed, exposed, and shared across different applications. This linking structure forms a directed, labeled graph, where the edges represent the named link between two resources, represented by the graph nodes.
Ontology (information science)

Ontology (information science)

In computer science and information science, an ontology formally represents knowledge as a hierarchy of concepts within a domain, using a shared vocabulary to denote the types, properties and interrelationships of those concepts.[1][2] Ontologies are the structural frameworks for organizing information and are used in artificial intelligence, the Semantic Web, systems engineering, software engineering, biomedical informatics, library science, enterprise bookmarking, and information architecture as a form of knowledge representation about the world or some part of it. The creation of domain ontologies is also fundamental to the definition and use of an enterprise architecture framework. The term ontology has its origin in philosophy and has been applied in many different ways. The word element onto- comes from the Greek ὤν, ὄντος, ("being", "that which is"), present participle of the verb εἰμί ("be").
