Image Annotation on the Semantic Web

Many applications that process multimedia assets make use of some form of metadata that describe the multimedia content. The goals of this document are to explain the advantages of using Semantic Web languages and technologies for the creation, storage, manipulation, interchange and processing of image metadata. In addition, it provides guidelines for Semantic Web-based image annotation, illustrated by use cases. Relevant RDF and OWL vocabularies are discussed, along with a short overview of publicly available tools.

It is not an HTML Tidy or a TagSoup cleaner or a semantic Houdini pulling knowledge out of thin air.

The content at the original URIs must be readable as one of the syntaxes Raptor knows - RDF ones, RSS, Atom, Microformats that have a GRDDL profile and so on.

TechnicaLee Speaking: Using RDF on the Web: A Vision

(This is the second part of two posts about using RDF on the Web. The first post was a survey of approaches for creating RDF-data-driven Web applications.) All existing implementations referred to in this post are discussed in more detail and linked to in part one.

Logic as the science of Garbage Collection

So what is an inferencing database? It's a database that can garbage collect redundant data.

REST without RDF is only half as bad as SOAP

Of all the xml data formats (as opposed to markup formats such as xhtml or OpenDocument, which is not my topic here), RDF is the one that takes the lessons of REST to heart. In RDF every concept, every relation, every object has a permalink so to say, a fixed URI that identifies it.

Le Web Sémantique en entreprise : comment et à quels niveaux ?

by 6 others, 4 comments
Bien qu’elle ait été lancée par le W3C dés 1998, l’initiative du Web sémantique [1] reste encore aujourd’hui marginale face aux problématiques courantes du Web, comme par exemple la publication de contenu. Pourtant, le WS est déjà riche de nombreux langages et outils qui peuvent trouver leur place au sein de l’entreprise, et améliorer la manière dont celle-ci traite, organise et publie ses données.

Policy based access control for an RDF store

Resource Description Format (RDF) stores have formed an essential part of many semantic web applications. Current RDF store systems have primarily focused on efficiently storing and querying large numbers of triples. Little attention has been given to how triples would be updated and maintained or how access to store can be controlled. In this paper we describe the motivation for an RDF store with complete maintenance capabilities and access control. We propose a policy based access control model providing control over the various actions possible on an RDF store. Finally, we discuss on how the Hypertext Transport Protocol (HTTP) and its extensions can be used to provide communication with the store.

RDF Gateway

by 1 other
RDF Gateway is a platform for the development and deployment of Semantic Web applications. The Semantic Web is an extension of the current Web that allows computers to understand the meaning of information published on it through the use of a new markup technology called the Resource Description Framework (RDF).
