Getting started with Linked Data Bathing Waters Pilot

2. short examples Getting started with Linked DataBathing Waters Pilot Alexander Coley Directives Reporting Service Manager 15th September 2010

3. introduction • why we are interested in linked data • our current issues • our questions • where we’ve got to • where next…

4. Laboratory analysis Sampling happens Defined sampling point Results processed Results published Defined Bathing Water a quick guide to Bathing Waters

5. a quick guide to Bathing Waters annual compliance location data sample data associated info

6. January the “Bathing Waters” year start of season Press interest 15th May bathing season 20-22 samples in 22weeks 30th Sept annual report November December

7. Why (the project)…

8. a quick guide to Bathing Waters

10. transparency • supporting big society (& community tools) • information access (& linking to our environmental outcomes)

11. issues…

12. knowledge • experience • skills • money • resources • culture (which may include IP)

13. our questions

14. licensing • data structuring (location/not location etc) • code lists • what data • update frequency • URI framework • managing the data

15. progress…

Namespace is to make the ID’d unique - probably should not have org names namespace inspire theme localID feature type

19. Reference Data:Bathing Water's (Spatial Thing)URI Pattern: http://environment.data.gov.uk/id/{eubwid}

21. Reference data: • a data.gov.uk style URI set for the UK bathing waters that we monitor • INSPIRE 'style' spatial-objects for the sampling points (as an abstraction of a bathing water). • Observation data: • in-season in-year weekly sample data • annual compliance assessment results • the vocabulary definitions that have been created or reused: • a snapshot of the cube vocabulary (reused) • cube based DSDs for in-year sample and annual compliance data and supporting definitions (reused –in part) • vocab companion to the bathing water URI set (potential for EU wide) • vocab companion to the sample point 'spatial-objects‘ (wider potential) • John Goodwin/OS spatial relations vocab (reused) What was needed…

22. 205776 observations in demo set how much data? Does this matter? Probably not in reality x4 just to link observations to the 4 slices

23. next…

24. api view • UI view(s) • finish & report pilot (!) • open data (fully & unrestricted –intention is to very soon do this for these data) • beta approach (& community apps) • managing the data (@ our end – within our data lifecycle) • revised Bathing Waters directive • others develop apps • other data & links (e.g. OS boundary & WFD waterbodies)
