Open Data and APIs Pieter Colpaert
Making Open Data used and useful, worldwide, since 2004
and many more
Open Definition.org A dataset is open if anyone is free
to use, reuse, and redistribute it — subject only, at most, to the requirement to attribute and/or share-alike.
Publicdata.eu
5 things an Open Data Portal does ★ A dataset
registry ★★ A meta-data provider ★★★ A co-creation platform ★★★★ A data publishing platform ★★★★★ A common data hub http://pieter.pm/5stardataportals/
Confusing World of APIs ? World of Open Data
You don’t need an API to publish data APIs enable
services on top of open data...
You use APIs to… gather feedback This toilet needs cleaning
Openly licensed data dump at: http://wiki. openstreetmap.org/wiki/Planet.osm
You use APIs to… use data in apps But… are
hypermedia interfaces APIs? REST API docs at: http://community.openspending.org/help/api/rest/ Raw data at: https://openspending.org/datasets
You use APIs to… use data in apps But… are
hypermedia interfaces APIs? See a list of government services in your browser GET http://{yourcity}/services Accept: “text/html” Get a JSON feed in your apps GET http://{yourcity}/services Accept: “application/json” Wouldn’t this be great?
First steps… Check out http://demo.TheDataTank.com CSV XML SHP SPARQL XLS
... http://... interface
You use APIs to… provide updates https://data.irail.be/NMBS/Liveboard/ Ghent%20Sint%20Pieters/ 2014/03/27/14/20 .json
Raw data at: http://datahub. io/dataset/timetables-for-the-belgian- railway-company Sliding windows of data
You use APIs to… provide services Full text search, autocompletion
API, querying interfaces (public SQL endpoints?)...
Open Data and APIs, where’s the money? Service Level Agreements
for data
