{ RDF and Turtle

Resource Description Framework
http://www.w3.org/RDF/

“a standard model for data interchange on the Web [that]
extends the linking structure of the Web to use URIs to name the
relationship between things as well as the two ends of the link
(this is usually referred to as a “triple”). Using this simple model, it
allows structured and semi-structured data to be mixed,
exposed, and shared across different applications.”

Turtle: Terse RDF Triple Language
http://www.w3.org/TeamSubmission/turtle/

“a textual syntax for RDF that allows RDF graphs to be
completely written in a compact and natural text form, with
abbreviations for common usage patterns and datatypes.”

{ aside: Pelagios and OAC

Pelagios Project
http://pelagios-project.blogspot.com/

its aim is to help introduce Linked Open Data goodness into online
resources that refer to places in the Ancient World

Open Annotation Collaboration (OAC)
http://www.openannotation.org/

to facilitate the emergence of a Web and resource-centric
interoperable annotation environment

{ aside: Open Annotation Collaboration Data Model

An Annotation is a document identified by an HTTP URI that describes an
association created between a Body resource and a Target resource. The
Body must be somehow "about" the Target for it to be considered the body
of an Annotation.

Both the Body and the Target of the Annotation can be any resource on the
web, identified by a URI. As such, they can have representations in any
format or language (or no language), or have no representations at all, such
as for abstract resources that denote a concept.

{ Thoughts for Discussion (from Leif)

1. HTTP URIs are more important than ontologies for connectivity
2. A Little Ontology Goes a Long Way
3. We should grow the Web of Data, not build it
4. The Web is designed for scale. Scale requires Openness.
