I just came across an easily readable and accessible short series on the semantic Web by Sunil Goyal of the enventure blog. The four-part series consists of:
- Part 1 — introduction and overview of various Web services
- Part 2 — the challenges of data integration
- Part 3 — RDF and OWL data models and service-oriented middleware, and
- Part 4 — user applications, enterprise systems, research applications and themes and services.
If you are new to this topic, you may find this series an easy first introduction.
