Today I enjoyed giving an invited lecture about "Semantic Pipes- Towards Web 3.0 Information Systems"* to the post-graduated students ("Research and Technology" course, CS671), at the University of Cyprus.
The first part of the lecture gives an introduction about Web 2.0 (Wikis, RSS, Blogs, Mashups, and a live demo about Yahoo Pipes). Although these technologies have shown a great success on how people can collaborate to produce and share content on the web; however, these technologies are still being used for social-oriented web pages. To expose these technologies for business and enterprise applications (i.e. to use it in business), we discuss (in the second part) how to build a Web Information System, where the information sources are distributed over different locations and edited by different people. Similar to the idea of Yahoo Pipes (that processes and mashes up RSS feeds easily), Semantic Pipes can be built to process and query RDF information sources. RDF is not only a well-structured data format, but it enables also the data semantics to be well-defined.
Querying RDF can be done using SPARQL (the RDF query language). In this way, querying multiple RDF sources in SPARQL, processing and storing these queries, and reusing them later -similar to Yahoo pipes- would not only enable information reuse and sharing, but it would also enable meaningful integration, search, access, and interoperation, which are the necessary services for a Web Information System. In this way, one can imagine a Web Information System as a database, where "tables" are seen "RDF sources" (distributed over different locations), and "views" are stored SPARQL queries.
Transforming the data on Web into such databases is called Web3.0.
