Take a moment and think…

“OH, I wish i could see connections between this and this and this and that without searching everywhere and drawing my own mindmap…!”

What is Linked Open Data?

Guidelines to publish, structure and link data on the web

Web of data Semantic Web technologies

“Linked data is the first practical expression of the semantic

web, useful and doable today, and applicable to all forms

of data.” (http://structureddynamics.com/linked_data.html)

linked data and semantic web

Linked data

Semantic web - a machine readable set of standards URI, HTTP, RDF, SPARQL (W3C)- a vision to improve meaning in content on the web by defining relations between data

2ND

Linked open data as the original web

Semantic web enables

a linked open data web

What is Linked Open Data about?

Bottom line

The more data being provided and made available to the public as OPEN, LINKED and accessible with semantically defined content..

…the smarter our applications can be..

From databases to graphs

Hvorfor?

Group & define

The challenge with hierarchies and classification

People look for patterns

Interpretation has always been difficult

As always – people are different and as situations change, context changes

How about…

Don’t put data into tight boxes that are hard to reach down into and drag something out of… › the coat most often gets wrinkled…› A triangle doesn’t fit in a round hole..

And create a nice pair of shaded sunglasses for the data set to wear at appropriate occations…?
