The Semantic Web, a knowledge-centric model for the Web's future, supplements human-readable documents and XML message formats with data that can be understood and processed by machines. SPARQL Protocol and RDF Query Language (SPARQL) is to the semantic Web as SQL is to a relational database. It allows applications to make sophisticated queries against distributed RDF databases, and is widely supported by many competing frameworks. This tutorial demonstrates its use through the example of a team tracking and journaling system for a virtual company.
<p>Natasha Lloyd unveiled an application she has built using OpenAmplify. According to Natasha, "Overall, I am impressed with OpenAmplify for two reasons.

Rather than building applications themselves, the OpenAmplify team provides the tools for other people to do it."</p>...
SMOB is a distributed / decentralised microblogging system built on RDF and Semantic Web technologies, mainly SIOC and FOAF. Currently, we have simple prototypes of a publishing and an aggregating service, less than 100 lines of PHP code each.
Twitter2RDF. An RDF exporter for Twitter microblogs has been created that uses SIOC (for the microblog entries) and FOAF (for describing the people). For example, here are representations of Twitter microblogs for two users: captsolo and johnbreslin.
This document provides a tutorial on how to publish Linked Data on the Web. After a general overview of the concept of Linked Data, we describe several practical recipes for publishing information as Linked Data on the Web.
