Ontology with all internet resources

Hi,

I know freebase and dbpedia, but I dont know a project that objective is
create a ontology of all internet resources.

The internet today have about 50 billions web resources (
www.worldwidewebsize.com).
If the metadata about each resource have about 2 KBytes, will be necessary
about 100 TBytes to store this.

Do you if there is a project that I can ask by API and retrieve metadata
about any web resource?
For example get some dublin core metadata about an article or video.

I think google, yahoo, microsoft are working right now in projects like
this, but there is a project that is open and distributed ?

Of course ontology learning should have a big place in this project
for ontology enrichment.

Thanks,
