Make a Linked Data SOS call, in some form: plain English (or other 
language) mail, tweet etc., a URL to nothing (i.e., I would someday like 
to access Structured Data from here), whatever. Key thing is making a 
request for the structured data you couldn't find or the query that you 
would like answered (as you did re. Tomatoes).

The process of discovering, scraping, and transforming is getting more 
automated by the second in a myriad of ways.

Here is an old animation showing how the process of Sponging works re. 
Generation of RDF based Linked Data from existing Web accessible 
resources [1].

And you can pass that through URIBurner [2][3] and start the process of 
exploring a progressively constructed Linked Data graph via the 
Descriptor Documents it generates from the Del.icio.us links.

Depends, Data is not only like Electricity, it carries the Subjectivity 
factory of Beauty :-)

Of course not, what you need is Search++ (Precision Find across 
progressively assembled structured linked data meshes) [4] .

Take a look at my collection of saved query results and queries (the

If it stumbles across the DBpedia Data Space on the way, naturally [5].

Always.

middleware will contribute to the burgeoning Web of Linked Data (first 
version of this animation was shown in 2007)
2. http://uriburner.com -- a service that generates structured 
descriptor documents for existing Web resources (e.g. Web Pages)
3. http://ode.openlinksw.com -- a browser ext. or bookmarklet that 
connects you to the public URIBurner instance (which is just a Virtuoso 
Sponger Middleware instance) or your own instance (wherever that may be 
including your private network or desktop etc.)

public use of items #2 and #3 above + services like PingTheSemanticWeb 
and Sindice and other sources)
