Dieter,

Do you mean: I would a place where I can search for vocabularies and 
assess their usage across LOD datasets? Goal being reuse of existing 
terms re. new datasets coming into the burgeoning LOD cloud?

If the above is true, the you can do the following:

1. Goto http://lod.openlinksw.com  -- the live 15 Billion+ triples LOD 
Cloud Cache we maintain
2. Enter a text pattern (with Class, Property, or Vocabulary discovery 
in mind)
3. On receipt of the initial results page, use the Links in the 
Navigation section to filter by Type or other Attributes (so you are 
looking for Entities of type: Ontology or Class or Property
4. Once you find one of the Entity Types above, click on the "describe" link
5. At this point navigation should be obvious i.e. you can use 
isDefinedby to find the Ontology associated with Classes and Properties 
or use the inverse relations to find the Class and Properties defined by 
an Ontology.

Hope this helps.
