semantic web(2py)

The idea of the semantic web, embodied by Linked Data, is that of  
labeling relations between data using the Web Ontology Language (OWL)  
and post the data online using an XML based protocol (RDF). Now you  
can do it in web2py by simply labeling fields and tables in the  
Database Abstraction Layer (DAL) with .rdf={...} and installing this  
plugin. The plugin exposes a web service that publishes your database  
as Linked Data (only tables labeled with rdf). This system works with  
new and with most legacy databases. It transparently supports SQLite,  
MySQL, PostgreSQL, MSSQL, Oracle, FireBird, Informix, DB2, Ingres, and  
the Google App Engine.
