Linked Open Data

“linked open data describes a method of publishing structured data so that it can be interlinked and become more useful.”

My repository!

• Links different kinds of datasets making the WORLD a single big repository!

•Private data and public data can be mixed, enabling companies and individuals to make better decisions and generate innovations.

Step 2 – Consuming observation measurements

Europa Linked Observation Browser 21

• List observed phenomena (e.g. water level, water temperature, etc.)• Correlate observed phenomena (e.g. Water level and Wind speed).• Project in a virtual globe where the phenomena is being measured.• Enables temporal queries .• Shows a time-series animation of the choosen phenomena.

Step 3 – diving into the semantic web(Asking spatial-thematic questions)

Europa Linked Observation Browser 22

• Which cities are around the flooding area?• Which museums are around the flooding area?• Which cultural heritages are around the flooding area?

• Which of them have been destroyed and which of them are still in danger? (proximity)

Europa Linked Observation BrowserWrapping up...

• Provides a high interoperable platform for linking observation data to the semantic web.

• Enables the correlation of observation data and any other relevant data availabe in the web.

• Makes observation data discoverable not only by the browser, but for the rest of the web (World).

• Enable time-series animation for a better visualization of the observed phenomena.

•It is totally supported by the SOS developers.

•It is awesome!
