The acronym stands for: Resource Description Framework. And
that's just what it is.
RDF is comprised of a Data Model (EAV/CR Graph) and Data Representation Formats
such as: N3, Turtle, RDF/XML etc.
RDF's essence is about: "Entities" and "Attributes" being
URI based, while "Values" may be URI or
Literals (typed or untyped) based.
URIs are Entity Identifiers.
Short for "Web of Linked
Data" or "Linked Data Web".
A term coined by TimBL that describes an HTTP based "data access by reference pattern" that uses a
single pointer or handle for "referring to" and "obtaining actual
data about" an entity.
Linked Data uses the deceptively simple messaging scheme of HTTP
to deliver a granular entity reference and access mechanism that
transcends traditional computing boundaries such as: operating
system, application, database engines, and networks.
Linked Data simply mandates the following re. RDF:
Note: by Entity I am also referring to: a
resource (Web parlance), data item, data object, real-world object,
Linked Data is also about, using URIs and HTTP's content
negotiation feature to separate: presentation, representation,
access, and identity of data items. Even better, content
negotiation can be driven by user agent and/or data server based
quality of service algorithms (representation preference order
To conclude, Linked Data is ultimately about the realization
that: Data is the new Electricity, and it's conductors are URIs
Tip to governments of the world: we are in
exponential times, the current downturn is but one side of the
"exponential times ledger", the other side of the "exponential
times ledger" is simply about unleashing "raw data" -- in
structured form -- into the Web, so that "citizen analysts" can
blossom and ultimately deliver the transparency desperately sought
at every level of the economic value chain. Think: "raw data ready"
whenever you ponder about "shovel ready" infrastructure

This document is empty and basically useless. It is generated by a web service that can make some statements in HTML Microdata format.
This time the service made zero such statements, sorry.
