Maximizing benefit of Open Data through Linked Data Services
- 1. Maximizing benefit of Open Data through Linked Data Services Dave Reynolds @der42
- 2. Who are we? Help organizations exploit Linked Data through: – – – – – Consultancy Training Data hosting Applications development Software tools Customers include: Land Registry Environment Agency Cabinet Office Ordnance Survey DEFRA The National Archive BBC MetOffice Bristol CC
- 3. Many reasons to open data Identifying best practice and waste How can I deliver a more efficient court service Supporting informed choices Helping parents identify the best school for their children in a locality Choice “Sunlight is the best disinfectant’ Publishing financial data, contracts, and Job holders above SCS1 Accountability Raw material for enterprise to build with Life Sciences – the NHS is global data centre for innovation Economic Growth Public Sector Productivity Transparency & Open Data Driving up quality and improving outcomes Publishing comparable data on GP outcomes Public Sector Outcomes Social Growth Helping people help themselves By accessing personal health records online.
- 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
- 6. Which users? Data scientist? Partner public bodies? Developers? flickr © yandle Citizens? Field workers?
- 7. each of these users have different requirements for how they access the data and the support they need
- 8. Beyond the data dump ... flickr © fdecomite
- 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
Hinweis der Redaktion
- 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
