The Web Becomes Semantic

●Originally:● Metadata about “Web” things (documents)

●Eventually:● Metadata about all sorts of things● And about relationships between things

●TBL’s original vision (Weaving the Web – 1999)●Then: Focus on Machine Reasoning

● Scientific American Article●Now: Focus on things & links

● Reasoning & Inferencing less central

Semantic Web Terminology

●Resource: Any “thing”●Class: Abstraction of a type of thing●Individual: An instance of a class●Property: An attribute of an individual●Statement/Triple:

● A Resource (subject)● A Property (predicate / verb)● A Value (object) - Nodes

●Graph: Visual Representation of statements●Ontology/Vocabulary: A domain specific collection of classes and properties

Linked Open Data

●Use URIs as names for things ●Use HTTP URIs so that people can look up those names. ●When someone looks up a URI, provide useful information. ●Include links to other URIs. so that they can discover more things. http://www.w3.org/DesignIssues/LinkedData.html

2014-04-11 Harper - Penn Humanities Forum - LODLAM 6

Linked Data

●Metadata as a Graph●Typed “things”, named by URIs●The relationships between those things, also built on URIs●Ease of integration *across* data sources – “merging graphs”

DBpedia

Structured Wikipedia Data●Partial basis in data entry conventions●InfoBox’s, and InfoBox Templates●Metadata Entry Format●Partial source of Ontology

● Class Structure● Vocabulary Design

2014-04-11 Harper - Penn Humanities Forum - LODLAM 10

DBpedia

●3.4 Million “things” described●Ontology based on “infoboxes”

● 1.5 million things classified● http://wiki.dbpedia.org/Ontology

●Approx. 50,000 “Properties”● Approx. 1,200 defined in ontology

Annotations

●The Pundit (thepund.it)●Hypothesis: Peer Review for the Web (hypthos.is)●Open Annotation Collaboration●Distributed bibliographic control environment

● Focus on identification over description

“In short, by treating values as non-literal resources and assigning URIs to them we give ourselves (and others) the hooks on which to hang further descriptions.” - Andy Powell

Context

Narrative

Story telling

The Library's story,

and the Archives story,

but also…

Open Refine RDF Skeleton

2014-04-11 Harper - Penn Humanities Forum - LODLAM 40

And onward...

• Rethinking UI Design Aggregate data from more sources Provide more context

• Building proofs of concept

• Improving Search Engine Optimization (JSON-LD, Schema.org, RDFa, &c.)

• Use cases!

• Experimentation!
