Yesterday, Google announced support for lightweight semantic markups; RDFa and microformats which is a big issue for the future of web and also know as semantic web. Yahoo has been making experiments with RDFa and microformats with their new search engine called search monkey. I assume Microsoft’ Live and Powerset will add same (may be full RDF) support soon.
So, the important point is; it is a big push to the current web to shape it more meaningful way. Why should a market dominant do it? Google search engine is powered with NLP (Natural Language Processing) and it works very well but it may be useless when compared future data on the web. NLP is a powerful technique which is aimed to translate spoken languages to machine ones to process, analyze and use it. There are many languages in the world which Google has to deal them separately and it is doing it very well. So, what is the challenge? It is social networks.
It is easy to manage your web site or web page content by yourself and ensure that it is well formed and correct for search engines. However, it is impossible to manage user distributed data over social networks. And, the easiest way to do it; add semantics to the content which will help search engines (or whatever you have) to process it.
I guess this push will improve the feature of the web and also semantic web. It seems we are going to see more tools, libraries, frameworks built in support for RDFa and microformats.
