  3. The Plan • Introduction • How to do the “Five Stars” • The Process at the University • The Pragmatics at the University • Group Breakout • Coffee • Feedback from Groups • Discussion and Planning

  4. Before You Start • Dataset Audit

  5. Where • Database • A spreadsheet on someone’s PC

  6. What • Low hanging fruit • Facilitate linkage • “Pivot” sets • Privacy • Trust • Identify “dangerous” datasets • Recognisewhat may cause trouble

  7. When • Static or Dynamic • Release frequency

  8. One Star • Put your Data on the Web

  9. ✰Put Your Data on the Web • any format • license is important! (any license is better than none) • highlight data.gov.uk portal or data.london.gov.uk • -- index of resources, data and applications • -- metadata (CKAN?) • -- forums, etc • -- easy to find, clear license, easy to reuse • -- sotonprob needs similar portal

  10. Two Stars • Make it Available in a Machine Readable Format

  11. ✰✰ Make it Available in a Machine Readable Format • highlight problems of PDF and images • some simple structure • spreadsheet, database dump • summarise best practises • -- clean, regular data • -- put comments in separate fields, etc • -- column headings

  12. Three Stars • Use an Open, Standard, Format

  13. ✰✰✰ Use an Open, Standard, Format • proprietary software is bad • eg excel: wacky formatting, difficult to use by scripts and other tools • Use an open standard: XML, JSON, CSV, RDF • (Intro to RDF, ontologies.)

  14. Four Stars • Use an Open, Linked Data, Format

  15. ✰✰✰✰ Use an Open, Linked Data, Format • (Intro to linked data publishing -- a single dataset, no linkage) • Fundamentally use URIs to identify things • put RDF descriptions at those URIs (ie resolvable) • common identifiers • can now refer to things • a linked data platform usually does all this for you

  16. Five Stars • Link Your Data to Other People’s Data

  17. ✰✰✰✰✰ Link your Data to Other Peoples’ • Forming the 'web of data' • find extra info • sameAs, CRS, etc

  18. The Process at the University • not really much of a technical piece. we don't want/need to tell them this is *how* we're going to do it from a technical point of view (indeed this hasn’t even been thrashed out properly yet). it's more about *what* is likely to be implemented across the University in a socio/political sense. • need to tell the audience that this is being mandated at a high level. • who owns the overall activity? • social issues: • -- who's responsible for what? (to which star level?) • -- who in which parts of the organisation is doing what?

  19. The Pragmatics at the University

  20. Group Breakout • What does it mean for you? ✰Put your Data on the Web ✰✰Make it Available in a Machine Readable Format ✰✰✰ Use an Open, Standard, Format ✰✰✰✰ Use an Open, Linked Data, Format ✰✰✰✰✰ Link Your Data to Other Peoples’ Data • Raw Data Now! • Just Enough Ontology! • Perfect is the Enemy of the Good!

  21. Feedback From Groups

  22. Discussion and Planning

  23. Divider page title goes here.

  24. Caption for the image should be placed in a clear area on the image to ensure it is legible

  25. Page title • Try not to use more than four or five bullet points per page to avoid the page becoming too cluttered • Keep each bullet point to one or two lines if possible • Third bullet point • Fourth bullet point • Fifth bullet point

  26. Page title • First level bullet points may need expanding into second level bullet points • Second level bullet point • Second level bullet point • Second level bullet point

  27. Page title • Bullet point • Bullet point Always try to provide a caption next to your picture in this style

  28. Page title • Bullet point text Always try and provide a caption next to your picture in this style Where two or more pictures are used, line them up with one another

  29. Page title • Use colours from the palette when creating graphs and charts – follow the example below

  30. Further reports • Use the colours from the palette when creating graphs and charts – follow the example below
