4. Just publishing the data doesn’t, of itself,
deliver any of these
You need people to:
– find your data
– understand it
– do something with it
5. So make sure you get those benefits
maximizing the reach of your data
– intrinsic value of the data
– direct and indirect support for use
• training and documentation
• demonstrators
• competitions, hackdays, recognition
– get data to your users
• in a form that works for them
• with context and connections to make it useful
9. What’s wrong with data dumps?
Good things:
– low cost to publish
– universal, wide range of tools
– power users will always want this
Issues:
– what if I only want a small part?
– what do the entries means?
– how do I keep it up to date? change v.s. correction
– how do the terms here relate to my other data?
10. Focus of talk
set of open web standards for data publication
– supports data services, not just bulk down loads
– enables datasets to be connected, contextualized
Linked Data
illustrate via case study of environmental data

24. Adopting this approach delivered ...
• very broad reach for data
– public, third sector, local government, beach operators
• simplified operations
– publish once, use many
– replaced separate publishing chains by simple apps
• integrated view over the data
– measurements, assessments, profiles, predictions
• incrementally extend over time
– series of small steps, just pour more data into the platform
But where are the links?

50. Essence of Linked Data approach ...
• break information into set of resources
– bathing waters, sampling points, individual assessments
• give each a web address, URL
– so you can reference it and fetch information on it
• this enables you to
–
–
–
–
connect data, across organizational boundaries
incrementally extend data
always access the latest version
put information in context so it can be understood
• based on open (W3C) standards
– data representation, vocabularies, query
51. Messages
Maximize the reach an impact of your data:
– provide multiple delivery channels
• publish once, use many
– link to other data sets
• context and value
– provide reference data that others can link to
• eco-system of connected data
– consider use of Linked Data open standards as a
means to achieve all this
Notes de l'éditeur
Brief, highlight Land Registry earlier talk
Heard many great examples and advice throughout the day ...
Just publishing doesn’t delivery those benefitsNeed people to see the data, understand, exploit itA number of factors ...
These groups have different skills, different requirements for how they access your dataJust posting a spreadsheet “dump” may not be enough to get your data used
Pick one running example of Linked Open Data published by Environment AgencyJust an example – EA have other LOD datasets and other psb, including ones we’ve heard from today such as LR, have adopted similar approaches
