WHY OPEN DATA?

SLIDE 20
HOW?
SLIDE 21
- 1. IDENTIFY THE DATA
YOU HAVE
SLIDE 22
PRIMARY DATA
- takes effort
- collect
- maintain
- and investment
- people
- equipment
- examples
- Met Office
- book publishers
- census
data collect maintain people equipment
SLIDE 23
EXHAUST DATA
- support activity
- no extra effort
- no extra cost
- examples
- till receipts
- phone usage
- customer data
- accounts
data as usual as usual
SLIDE 24
DO YOU OWN IT? created data derived data bought data
you own the data you gather you might own data you calculate from others' data you almost certainly don't own data you've got from someone else
SLIDE 25

<a resource="{{database-url}}" rel="license" href="{{licence-url}}"> {{licence-name}} </a> Link: <{{licence-url}}>; rel=license
in HTML in HTTP

- 4. ITERATE & IMPROVE
SLIDE 32
TECHNICALL Y
- standard formats
- APIs help some reusers
- dumps help other reusers
- whole dataset analyses
- also provide feeds of changes
- links & link relations
- pull together disparate sources
SLIDE 33
HIGH QUALITY OPEN DATA
- make it trustworthy
- accurate, timely
- guaranteed availability
- create a community
- feedback, including APIs
- discussion lists
- code libraries
SLIDE 34
CHALLENGES
SLIDE 35
WE DON'T KNOW YET
- which business models work
- which licences drive good behaviour
- how to measure open data use
- how to make data findable
- whether data formats really matter
- whether links in data really matter
- whether the world is better in the end
