This page provides a structured representation (serialized as HTML+RDFa) of the description of the entity denoted ("referred to") by the hyperlink that anchors the About: <Entity Label> text at the top.
The data is presented here in the form of a collection of Entity->Attribute->Value (EAV) or Subject->Predicate->Object (SPO) relations.
In conformance with core Web Architecture, the same description data may also be retrieved in a variety of other negotiable serialization formats, which currently include CSV, HTML+Microdata, (X)HTML+RDFa, N-Triples, Turtle, N3, RDF/JSON, JSON-LD, RDF/XML, Atom, and CXML.
This page and its neighbors provide 5-Star Linked Data URIs (Web Super Keys) for HTTP-accessible data. These URIs are powerful starting points for serendipitous data discovery using the Web's "follow your nose" pattern, as well as a key ingredient for SPARQL queries over HTTP, ODBC, JDBC, ADO.NET, OLE-DB, or XMLA connections.
A single link from this page can be the seed of a powerful Web traversal, en route to discovery and exploitation of unimagined insights, using existing tools such as browsers, spreadsheets, business intelligence and analytics packages, basic report writers, presentation generators, project management packages, and many others.
A variety of discovery pointers are available to users and user agents (software programs) that include:
<link />
relations embedded within the <head />
section of each description page Link:
" response headers included as part of HTTP response metadata.Yes! Simply include entries, based on the example below, in the <head/>
section of your (X)HTML page, whether static or dynamically generated --
<link rel="related" title="My Data in Linked Data form" href="http://linkeddata.uriburner.com/about/id/<scheme-part-of-url>/<host-part-of-url>/<path-part-of-url>" />
The scheme part is the first bit of a URI, up to but not including the first colon (":
").
The host part includes the port, if any, and is found between the double solidus ("//
") following the first colon, and the first solidus ("/
") thereafter.
The path part is everything thereafter (possibly including a query part or fragment identifier part).
For example, if your original page were at --
http://en.wikipedia.org/wiki/Linked_Data
-- the scheme part is "http
", the host part is "en.wikipedia.org
", and the path part is "wiki/Linked_Data
".
You could therefore provide access to a Linked Data graph rendition by including a <head/>
entry like this --
<link rel="related" title="Linked data - Wikipedia, the free encyclopedia - in Linked Data form" href="http://linkeddata.uriburner.com/about/id/http/en.wikipedia.org/wiki/Linked_Data" />
A transition is a Situation that creates a context for three TimeInterval(s), two additional different Situation(s), one Event, one Process, and at least one Object: the Event is observed as the cause for the transition, one Situation is the state before the transition, the second Situation is the state after the transition, the Process is the invariance under some different transitions (including the one represented here), in which at least one Object is situated. Finally, the time intervals position the situations and the transitional event in time. This class of situations partly encodes the ontology underlying typical engineering algebras for processes, e.g. Petri Nets. A full representation of the transition ontology is outside the expressivity of OWL, because we would need qualified cardinality restrictions, coreference, property equivalence, and property composition.
