Scotland's Environment Web Data Journey Dave Watson, Duncan Taylor

Session Outline SEWeb data journey –What has been encountered on that journey SEWeb as a data consumer –What do we do with the data? Five Star/Linked Data SEWeb Data – what next?

SEWeb Data Journey

SEWeb Brand – Daughter Web Sites

Data at Source

Dataset Progress ‘Data at Source’ – 55 WMS consumed by Map Viewer -> 239 Data Layers – 9 Rest Services consumed by Land Information Search (LIS) -> 39 Data Layers – 10+?? Non spatial data consumed by Visualisation Tools Five Star /Linked Data – 68 SESO Data, 12 Water (SEPA WFD), 1 Site Conditioning (SNH) Data Holdings – Soils/Aquaculture Daughter Sites – Project Finder

What do we do with the data? Themed spatial maps Advanced Maps Visualisation Applications Task Specific Applications Linked Data Repository

Themed/Advanced Maps

Task Specific Maps – Land Information Search

Visualisation/Discover Data

# Available on the web (whatever format) but with an open licence, to be Open Data # Available as machine-readable structured data (e.g. excel instead of image scan of a table) # # # as (2) plus non-proprietary format (e.g. CSV instead of excel) # # All the above plus, Use open standards from W3C (RDF and SPARQL) to identify things, so that people can point at your stuff # # # # # All the above, plus: Link your data to other people’s data to provide context Why Linked Data? - 5 Star Model of Open Data

Linked Data Four Principles 1.Use URIs as names for things 2.Use HTTP URIs so that people can look up those names. 3.When someone looks up a URI, provide useful information, using the standards (RDF*, SPARQL) 4.Include links to other URIs so that they can discover more things.

SENSE 3 – Schema Relationships

State of Environment Reporting Defined by chapters (air, water, land, etc) Chapters divided into topics, each with a summary quality assessment Datasets support and inform the assessment of the topic A dataset may be related to more than one topic Currently published as static pages

State of Environment Reporting Remodel as linked data Enable publication of metadata on datasets Link to data visualisation and download where available Provide contact details where data not yet published on line Provide support and examples of best practice to assist publication

SEPA as Data Provider

SEPA Reporting Requirements Information required at many levels Internal – SEPA corporate systems National – State of Environment; SEWeb European – Directive Reports; INSPIRE

Where we were… Many applications Many formats Many versions SEPA Database Reports GIS Applications Publications Website Information Requests EU Reporting

What we decided to do Focus on data – not applications Identify key reporting datasets Define them once Use them many times… …in many formats

Where we’ve got to Operational Database Reporting Database Publish Externally Defined data “products” Consistent metadata GIS Intranet Reports & Analysis SEWeb SEPA Website EU Reporting Consistent data

Where we’re getting to Operational Database Reporting Database Publish as WMS; WFS; Linked data Defined data “products” Consistent metadata GIS Intranet Reports & Analysis EU Reporting Consistent data Websites (SEPA, SEWeb,…) Partners Public EU

What’s helped Scotland’s Spatial Data Infrastructure – provided framework and standards for metadata SEWeb – prioritisation of datasets Government direction – “digital by default“ EU reporting frameworks – SEIS, SENSE

What we need now Agree to use existing standards and vocabularies Define new ones where appropriate Encourage use of common reference systems Encourage others to use the data

What we get out of it Wider (and cleverer) use of data Less bespoke development Fewer information requests to deal with Publish data once – let everyone else get on with it

Data Architecture

Linked Data

# Available on the web (whatever format) but with an open licence, to be Open Data # Available as machine-readable structured data (e.g. excel instead of image scan of a table) # # # as (2) plus non-proprietary format (e.g. CSV instead of excel) # # All the above plus, Use open standards from W3C (RDF and SPARQL) to identify things, so that people can point at your stuff # # # # # All the above, plus: Link your data to other people’s data to provide context 5 Star Model of Open Data

What is Linked Data? Data in which real-world things are given addresses on the web (URIs), and data is published about them in machine-readable formats. Describes a method of publishing structured data so that it can be interlinked and become more useful. Builds upon standard Web technologies such as HTTP, RDF and URIs, but rather than using them to serve web pages for human readers, it extends them to share information in a way that can be read automatically by computers. HTTPRDFURIs Enables data from different sources to be connected and queried.

Linked Data Four Principles 1.Use URIs as names for things 2.Use HTTP URIs so that people can look up those names. 3.When someone looks up a URI, provide useful information, using the standards (RDF*, SPARQL) 4.Include links to other URIs so that they can discover more things. ml
