Visited and found some ontology tendered as a reference ontology, 
http://www.aktors.org/ontology/. Here are the top lines:
"A very simple top-level. We define something called THING, which is the 
top-level concept in the ontology.  We then distinguish two basic
types of 'things': TANGIBLE-THING, something that has some physicality, and 
INTANGIBLE-THING, something which has not. We use a very open definition
of being tangible: obviusly a physical object is tangible, but also a 
sub-atomic particle is tangible, even if some of them are very tricky (you 
do not see them)
you only see the trace they leave behind.  Also a piece of software will be 
considered a tangible thing, it is something that you can see on a floppy 
In contrast an algorithm will be an intangible, although the file that 
contains its implementation will be a tangible thing."
Something more in this line: Intangible Thing is not tangible...Tangible 
Thing, something which is not intangible... Quantity is of two subclasses: 
Number and Physical Quantity, etc.
Wonder is it an experimental trial or completed work? Thanks.

Subject: ANN: Linked Data/Semantic Web Application - RKBExplorer

Dear Colleague,

We have revamped a lot of the RKB and RKBExplorer infrastructure since last
exposing it here, so you may well like to give it another visit at

There you will find a user interface to a world of Linked Data, although it
is specifically designed to avoid exposing users to any Linked Data or
Semantic Web technologies directly. We hope it looks like a "normal" Web 1.0
or 2.0 site.

The RKBExplorer gives consolidated views on a core set of Linked Data sites
(listed at http://www.rkbexplorer.com/data and comprising about 100M triples
at 40 domains), plus the many external Linked Data sites and resolvable URIs
for which it then finds references, notably dbpedia.org. This external
knowledge is discovered by dynamic browsing as well as dynamic co-reference
analysis, and the knowledge base for this co-reference (exposed at
http://sameas.org/) currently has over 6M different entities from 20M URIs.

The user domain is of workers looking to explore many aspects of researchers
and research topics, although the emphasis is currently around Computer
Science, and especially Resilient Systems.

The underlying infrastructure for all this is very open, with RESTful
interactions, and so available to anyone; however the purpose of this email
is to draw attention to the RKBExplorer as a (hopefully) useful application,
and a possible system that you might choose to use to demonstrate the power
of Linked Data and the Semantic Web to others. Feel free to pass on the URI.
Feel free to contact me if you think you might like to use a service.
