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

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

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

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

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

7 Why (the project) …

8 a quick guide to Bathing Waters

9

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…

16 linked data for Bathing Waters location data location.data.gov.uk environment data environment.data.gov.uk definitions environment.data.gov.uk reference reference.data.gov.uk other linked data data.gov.uk

17 Bathing Waters URIs Reference Data: Bathing Waters: Sample Point: inspire theme feature type namespace localID bwmp.eaew organisational dnf prefix Bathing Water Monitoring Point Current namespace is not really a name space but mixing with feature type Env Facilities theme – then MonitoringPoint & some sub-feature type may be better? Namespace is to make the ID’d unique - probably should not have org names Current namespace is not really a name space but mixing with feature type Env Facilities theme – then MonitoringPoint & some sub-feature type may be better? Namespace is to make the ID’d unique - probably should not have org names

18 Observation Data In-Year: Dataset: Observations: year/sample/date/{date}/time/{time}/point/{bwmpId} Slices: By Year year/slice/year/{year} By Sample Point year/slice/point/{bwmpId} By Sample Point + Year quality/in-year/slice/year/{year}/point/{bwmpId} By Week year/slice/week/{week}

19 Reference Data: Bathing Water's (Spatial Thing) URI Pattern:

20

21 Reference data: 1.a data.gov.uk style URI set for the UK bathing waters that we monitor 2.INSPIRE 'style' spatial-objects for the sampling points (as an abstraction of a bathing water). Observation data: 1.in-season in-year weekly sample data 2.annual compliance assessment results the vocabulary definitions that have been created or reused: 1.a snapshot of the cube vocabulary (reused) 2.cube based DSDs for in-year sample and annual compliance data and supporting definitions (reused –in part) 3.vocab companion to the bathing water URI set (potential for EU wide) 4.vocab companion to the sample point 'spatial-objects‘ (wider potential) 5.John Goodwin/OS spatial relations vocab (reused) What was needed…

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

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)

27 Getting started with Linked Data Bathing Waters Pilot Alexander Coley Directives Reporting Service Manager 15th September 2010 under the hood

28 Reference data: bwq-bathing-water.ttl a data.gov.uk style URI set for the UK bathing waters that you monitor bwq-sample-point.ttl INSPIRE 'style' spatial-objects for the sampling points (as an abstraction of a bathing water). Observation data: bwq-sample.ttl in-season in-year weekly sample data bwq-compliance.ttl annual compliance assessment result the vocabulary definitions that have been created or reused: cube.ttl a snapshot of the cube vocabulary def-bwq.ttl cube based DSDs for in-year sample and annual compliance data and supporting definitions. def-bathing-water.ttl vocab companion to the bathing water URI set def-loc-sp.ttl vocab companion to the sample point 'spatial-objects' spatialrelations.ttl John Goodwin/OS spatial relations vocab

30 URIs…

31 Bathing Waters URIs Reference Data: Bathing Waters: Sample Point: inspire theme feature type namespace localID bwmp.eaew organisational dnf prefix Bathing Water Monitoring Point Current namespace is not really a name space but mixing with feature type Env Facilities theme – then MonitoringPoint & some sub-feature type may be better? Namespace is to make the ID’d unique - probably should not have org names Current namespace is not really a name space but mixing with feature type Env Facilities theme – then MonitoringPoint & some sub-feature type may be better? Namespace is to make the ID’d unique - probably should not have org names

32 Observation Data In-Year: Dataset: Observations: year/sample/date/{date}/time/{time}/point/{bwmpId} Slices: By Year year/slice/year/{year} By Sample Point year/slice/point/{bwmpId} By Sample Point + Year quality/in-year/slice/year/{year}/point/{bwmpId} By Week year/slice/week/{week}

33 Annual Compliance: Dataset: quality/compliance Observations: quality/compliance/year/{year}/point/{bwmpId} Slices: By Year quality/compliance/slice/year/{year} By Sample Point quality/compliance/slice/point/{bwmpId}

34 Additions Versioning… what if we had to update a sample?: quality/compliance/year/{year}/point/{bwmpId}/{version} What if the monitoring point moved?: Note: If you don’t add version to uri string you would be returned newest version

35 Reference Data: Bathing Water's (Spatial Thing) URI Pattern:

36 Monitoring Point (Spatial Objects - but spatial objects are things too). URI Pattern:

37 In Year Observations Dataset

38 Individual In Year Observation URI Pattern year/sample/date/{date}/time/{time}/point/{bwmpId} year/sample/date/
