Editor's Notes
- Also Haiti, iPhone cycle map
- Allowing with JobCentresPlus, was highlighted as an innovative use of government data
- But linking data is even more powerful Health and economic data Dr. Hans Rosling, Professor of Global Health, Karolinska Institute, Sweden (TED talk)
- Geonames – lat/long of place names Dbpedia – munge of Wikipedia content e.g. Where do footballers in the premiership come from?
- Note: google maps here – Google have built their business on being very good at not only search, but linking data too. Map has restaurants, travel directions, traffic, related ads. This profits them, but what about the rest of society?
- One way achieve what hundreds of organised and motivated Google programmers do?
- Installing linux packages – really sophisticated system of downloading lots of modules and they work together Someone might combine a couple of datasets, may well do some cleaning, produce a graph, but doesn't give back the data. Also: Scraperwiki
- Core metadata based on debian package. No dependencies shown here, but we do have that too.
- Can also update via API. Also have python, php, Drupal, Wordpress and other clients to help access API.
- Lobbying governements, or just tocollect known datasets. Groups like ownership and personalisation of the site.
- clone/push/pull/merge/reject changes
