Summary

The article Tying Web 3.0, the Semantic Web and Linked Data Together understandably and in length explains the main concepts of the Semantic Web. It also reminded me of couple of things.The first one is 1,5 half years-old post on this blog Relational model does not fit the Web, which received some mixed response.The other one is something a had in my mind for a while, a list of very basic differences/advantages of RDF over the relational model:
your record ID (primary key) becomes URI, so you can define foreign keys pointing to any record in any data source on the Web
there are standard generic serialization formats, so you don't have to invent your own every time
the schema uses the same data model as the data, but the data can just as well live without any schema
it allows you to build applications that are generic, that is, can operate on different data without knowing its specific concepts and data types
schemas can be global, shared, reused, and extended
you can merge your databases without making any changes
Some more?
