RDFa Primer Annotated

Current Web pages, written in XHTML, contain inherent structured data:
calendar events, contact information, photo captions, song titles, copyright
licensing information, etc. When authors and publishers can express this
data precisely, and when tools can read it robustly, a new world of user
functionality becomes available, letting users transfer structured data
between applications and Web sites. An event on a Web page can be directly
imported into a desktop calendar. A license on a document can be detected to
inform the user of his rights automatically. A photo’s creator, camera
setting information, resolution, and topic can be published as easily as the
original photo itself.
This document is an introduction to RDFa, a method for achieving precisely this kind of structured data embedding in XHTML.

The Object Oriented Web – Part 1 – Backlinks – Blog – Semantic Focus Annotated

Let’s imagine that I want to make an online address book. The easiest way consists of storing the data myself; I will save my addresses in any database and that’s it. There is another approach, a little bit more complicated but so much more interesting: you can store some kind of links making it possible to get the informations back at the source at any moment. In my address book, for instance, I will have a record directly connected to my favorite restaurant. This restaurant has a Web site which includes exactly what I’m looking for: the restaurant exposes their details in a way that my address book recognizes, as the hCard format for example. Therefore I will subscribe my address book to this Web site.
if we want to someday achieve the World Wide Database dream, I think we should seriously consider the use of mechanisms for bringing subscriptions and “backlinks,” therefore allowing the semantic information to really “exist.”
