Government is opening up its data
So people can build services to help you ...
track crime in your area
understand where funding is going
plan travel
choose a school
... and much more

Traditional approach – data dump
each application does its own data integration
local stores which require management and update
hard to share or reuse efforts between applications

A web of government linked data
DCSF
AdminGeography
Edubase
Schools
TimePeriods
Ofsted
Gov.Bodies
common format
integrated through standardized reference identifiers
fine grained, programmatic web access

point
another point
no more
But there are some barriers ...
finding the relevant datasets (discovery)
single view of combined datasets
complexity
getting access from typical web development tools

Semantic data exchange
An information exchange
to help developers locate, access, combine and enrich the Gov web of data
to enable a network of information services for commerce and citizens

Using the data exchange
1. Locate datasets, indexed by relevant concepts

Data view
2. Construct a view over the combined data

Data view
3. Create visualizations of the data

Data view
4. Embed visualization
data view and associated visualization widgets can be shared and reused
