Here is the mind map of various web information sources. This is not an exhaustive list. I will have a few posts following that describe each one of these in more detail.
Look at this entry for some contextual information.
Update Jul 1, 2009
There are a whole host of new sources. So I will add them to comments and try to update this mind map once in a while.
Here are some:
– Freebase is a social database of open data
– Twine is a smart way to keep track of information and share it with others. It goes beyond simple bookmarking.
– data.gov is a fabulous source of US government information. Will try to find and add other similar resources for other governments.
What is Semantic Web? Why do we need it? What can we do with it? This cool video (about 7 minutes) offers the simplest description and covers a few aspects of the semantic web. We need more of these.
- Semantic Web is a layer on the existing web
- By adding additional data (referred to as metadata), applications can derive more meaningful data from the web
- It is a way to connect people and data
Eyal Oren also talks about the project he is working on – Semantic Desktop. Most of the existing semantic web literature focuses on how it works, the underlying technologies (like RDF, OWL). So it is nice to have a video where you get a non-technical explanation of what it is and what you can get out of it. Hope DERI will produce more of these videos.

Yesterday I watched the this video Making Sense of the Semantic Web by Nova, a presentation at NextWeb conference. It talks about a lot more about the third generation of Web (3.0) and applications of Semantic Web with a brief description of underlying technologies. If you don’t like the term Semantic Web and want to pick another, Nova suggests “The Data Web”. While the current web is like a file system, the Semantic Web is a like a database, says Nova. Definitely worth watching this video. Nova suggests FOAF and SIOC as the starting points if you want to dip your toes into Semantic Web applications.
SMOB is a distributed / decentralised microblogging system built on RDF and Semantic Web technologies, mainly SIOC and FOAF
The SMOB client enables you to publish your microblog postings. It provides a web interface for entering new postings, stores the postings, and lets the aggregators of your choice know of each new posting.
The SMOB client complements the SMOB server, which lets you set up your own microblog aggregators.
