  13. 13. What about the data? Open Data & Open Source Software at EDINA Diagram kindly supplied by Snowflake Software <ul><li>Making data available is great, but it should be in a usable format. </li></ul>
  14. 14. Where are we going? Open Data & Open Source Software at EDINA Images of front pages here…… Location Based Service – everything goes mobile……. TouchMap Lite app that streams OS Digimap OpenStream to a mobile. Not a native app. Augmented Reality – Look at the blog for a comparison of AR browsers. HTML 5 – making use of html 5 in particular Canvas. http://mab.edina.ac.uk/geomobile-test/osopen.html http://mobilegeo.wordpress.com/
  15. 15. Open Data & Open Source Software at EDINA What standards do we use Just some of the standards that we publish to or use in Geo-services at EDINA Service Standards Digimap WMS Digimap for Schools WMS Openstream WMS UKB/Open Boundaries WMS GoGeo CSW for metadata harvesting and publishing OAI for metadata harvesting ISO 19139 encoded metadata ShareGeo OAI-PMH – for metadata harvesting GeoDoc Xforms (user interface for forms) Xslt (XML schema transformation) eXist (xml based database management)
  16. 16. Open Data & Open Source Software at EDINA Standards http://www.flickr.com/photos/epublicist/3546059144/ <ul><li>Consensus approach </li></ul><ul><li>Standard design by the community for the community </li></ul><ul><li>Promotes interoperability </li></ul><ul><li>“ Plug and play” when combined </li></ul>
  17. 17. Why standards work? Open Data & Open Source Software at EDINA <ul><li>Standards give you something to work towards and test against. </li></ul><ul><li>Not quite a recipe to follow but you know what you should end up with </li></ul><ul><li>Allow others to easily consume your service </li></ul><ul><li>Should allow different components to fit together – “plug and play” </li></ul>http://www.flickr.com/photos/indieb0i/101943682/ Not mine, honest
  18. 18. OSGeo Open Data & Open Source Software at EDINA <ul><li>OSGeo projects represent software that: </li></ul><ul><ul><li>Complies with OGC standards where possible </li></ul></ul><ul><ul><li>Is tried and tested </li></ul></ul><ul><ul><li>Is stable </li></ul></ul><ul><ul><li>Is well documented </li></ul></ul><ul><ul><li>Has a community of support around it </li></ul></ul>http://www.opengeospatial.org/standards <ul><li>A project has to progress through incubation which helps achieve the criteria listed above and should install confidence in those that use the software. </li></ul>
  19. 19. Digimap case study Open Data & Open Source Software at EDINA <ul><li>So, how does this work in practice? </li></ul>http://www.flickr.com/photos/andivszf/4962765151/

  24. 24. Things to think about….. Slide of 18 Open Data & Open Source Software at EDINA Support, documentation, development Pick the right tool for the job – open or proprietary. Hybrid systems work Solutions should provide a flexible framework that can grow and evolve Work towards standards, this will make services interoperable and should allow for flexible development Proprietary vendors should integrate their product to fit your architecture Addy Pope Email: [email_address] Twitter: @go_geo http://www.gogeo.ac.uk EDINA website: http://edina.ac.uk

  27. 27. Open Interoperability Standards <ul><li>Many of EDINA’s systems implement Open Geospatial Consortium OpenGIS® interoperability standards </li></ul><ul><li>While we do not offer public WFS/WMS services, we do use: </li></ul><ul><ul><li>WMS, WFS, SLD, GLS, KML, GML… </li></ul></ul><ul><ul><li>Through various mapping / data download clients </li></ul></ul><ul><li>Our subscription services protected by Shibboleth authentication (implementing SAML to provide single sign-on and attribute exchange) and are free at the point of use </li></ul>Open Source Software & Open Interoperability Standards at EDINA
  28. 28. Hybrid Stack Open Data & Open Source Software at EDINA We use a mix of open source and proprietary software. Why? Well, we believe it provides us with the best solution that fits our requirements. Cartographic output better handled by GoLoader and GoPublisher are great for handling Mastermap Migrating away from this but tied to it for GoPublisher.
