What is Linked Data? – “This lesson is a short video lecture from Manu Sporny. He forgoes PowerPoint for whimsical, hand-drawn pieces of paper and hand gestures to introduce the subject of Linked Data for non-technical people. This lessons is more approachable than the longer, more in-depth Introduction to Linked Data, which you should visit after watching the video.”
Semantic Web Design Patterns – “Like a question on Stack Overflow, a design pattern is often posed as a question: how do we solve some design problem? However a design problem is, by its nature, nonspecific, and rarely has a single straight-forward answer. There might be several ways to solve the same problem, some better than others depending on the specific situation and the specific context of the problem.”
RDF vs. XML – “Say the words ‘semi-structured data’ and almost every technologist you talk to will think ‘XML’ and not ‘RDF.’ Tell one about RDF vs. XML and he’ll reply, ‘Why do I need something else? I already have XML for that!’ However, as a growing Semantic Web technology expert, you will patiently smirk and know that XML is simply not a substitute for RDF, and that it is very poorly suited for the distributed data linking that RDF is meant to do. This lesson will compare and contrast XML and RDF and make recommendations on when to use one vs. the other.
