I did not find a lot of info about his idea (Linked Data). Does anybody knows if there is a standard or something that is written at this time regarding his vision explained in this video?

see http://linkeddata.org/guides-and-tutorials

Basic principles are simple: use URIs to describe things and provide useful information about these things when requested:

It's just a user friendly term for Semantic Web.

Nope, the semantic web was about reasoning. Linked data is about linking data, and in effect creating a large distributed database. One way to think about it, is to consider building a system that stores a tracking code for a package. Instead of storing XXX-XXXXXX-XXX use the URI so that it can just be deferenced to get more information. In effect you are linking your store data with shippers data.

This could allow you to write trivial queries to quickly identify if there are bottlenecks in how your packages are shipped etc.

Also the development of SPARQL was a significant milestone, that really changes how one works with rdf.

A linked data web could then be used to for reasoning on top of it, but it would need to be large and thus it needs to be useful before the reasoning can be used. For instance, imagine the original web when people were working on search engines with only a few pages... The pages need to exist first.

Quoting Wikipedia: "Linked Data is a sub-topic of the Semantic Web. The term Linked Data is used to describe a method of exposing, sharing, and connecting data via dereferenceable URIs on the Web."

It's RDF all over again.

I wonder what's going to happen when you try to have actually dense data. I can't wait to download a 40gb fMRI file in RDF or whatever.

People do it, already. See for example http://esw.w3.org/topic/HCLSIG/LODD/Data

These are metadata, not numerically intensive data. There's plenty of file formats already out there - netCDF, HDF, etc.

I think almost none of the LOD cloud is metadata. It's all information like the population of Berlin, or the proteins which connect to some receptor.

I've seen some apps which are using RDF mostly for metadata, but in the life sciences world, we use it for the nitty gritty data.
