Much Simpler

The four micro principles of the Semantic Web

1.  All entities of interest, such as information
resources, real-world objects, and
vocabulary terms should be identified by
URI references.
2. URI references should be dereferenceable,
meaning that an application can look up a
URI over the HTTP protocol and retrieve
RDF data about the identified resource.
3. Data should be provided using the RDF/
XML syntax.
4. Data should be interlinked with other data.

The Shape of Linked Data
•  Micro principles to macro
phenomena

•  Shape and structure

•  Scale free

•  Preferential attachment

•  Communities

•  Values and obligations

•  Incentives

Open Government
Data: A Gift…

Introduction

•  Open Government Data is
creating waves

•  Governments, local authorities,
cities, organizations, individuals -
all releasing data

•  Tim Berners-Lee and myself
appointed 9th June 2009 and set
about creating data.gov.uk

•  Reappointed Public Sector
Transparency Board June 2010

Accomplishments

•  data.gov.uk itself (now with almost 4000
datasets)
–  Open source and open standards
–  Key data sets released inc OS OpenData,
COINS etc.
•  a new open licence for Crown Copyright
information

•  overcoming the many objections to
transparency of data

•  community of data users and developers
who hold the teams to account

•  political and technical leadership

Coalition Government’s
Commitments
•  Prime Minister’s letter to Ministers on Transparency
and Open Data - established Public Sector
Transparency Board

•  Creating a powerful new right to government data,
enabling the public to request and receive
government datasets

•  Publishing data in open and standardised formats

•  Transforming the culture of the public sector to one
that presumes datasets should be open and shared
with the public on an ongoing basis.

•  Bringing in new measures to enable to public to
scrutinise the government's accounts

•  Requiring public bodies to publish online job titles,
salaries and expenses of senior staff

•  Publishing in full government contracts for good
and services worth over £25,000 …

Public Data

"Public Data" is the
objective, factual, non-
personal data on which
public services run and are
assessed, and on which
policy decisions are based,
or which is collected or
generated in the course of
public service delivery.

Public Data Principles

•  Public data policy and practice will be clearly driven by the public and
businesses who want and use the data, including what data is released
when and in what form

•  Public data will be published in reusable, machine-readable form

•  Public data will be released under the same open licence which enables
free reuse, including commercial reuse

•  Public data will be available and easy to find through a single easy to
use online access point (data.gov.uk)

•  Public data will be published using open standards, and following
relevant recommendations of the World Wide Web Consortium

Public Data Principles

•  Public data underlying the Government’s own websites will be published
in reusable form for others to use

•  Public data will be timely and fine grained

•  Release data quickly, and then re-publish it in linked data form

•  Public data will be freely available to use in any lawful way

•  Public bodies should actively encourage the re-use of their public data

•  Public bodies should maintain and publish inventories of their data
holdings

Local Government Data

•  New items of Local
government spending over
£500 – council by council
from Jan 2011

•  New items of Local
government spending over
£500 – council by council
from Jan 2011

•  “Greater openness in
spending is the best way to
root out waste, spot
duplication and increase
value for money.”

29

And more to come…

•  New local government contracts and tender documents for expenditure over
£500 to be published in full from Jan 2011

•  …information on senior salaries, names and job descriptions, councillor
allowances and expenses, minutes and papers of council meetings, job
vacancies that will enable people to see why council wage bills are so high
and how many of the positions are for key local services frontline service
data - including rubbish and recycling rates, council tax collection rates and
detail of major planned projects data such as food hygiene reports for food
outlets - information which is routinely collected and of interest to residents,
but not currently shared in an easily accessible format

•  Crime data to be published at a level that allows the public to see what is
happening on their streets from Jan 2011

Data Publishing – Star Quality

★ Put your data on the Web (any format)

★★ Make it available as structured data (e.g. Excel,
CSV, instead of PDF)

★★★ Use open, standard formats (e.g. XML, RDF)

★★★★ Use URLs to identify things (so people and
machines can point at your data)

★★★★★ Link your data to other people’s data

Why 5★ Linked Data?

•  National digital
infrastructure being built

•  URIs for schools, roads,
bus stops, post codes,
admin boundaries...

•  Some of the data links
across and connects
other data together

•  Key data link points exist

Global Linked Data
This application presents a mashup of
foreign aid data (represented in US
Dollars) from the United States Agency
for International Development (USAID)
and UK Department for International
Development (DFID) for the 2007 US
Fiscal Year.

Users may retrieve foreign aid data for specific
countries by clicking on a provided world map
(shaded based on total combined contributions for
USAID and DFID). Upon clicking on a desired
country, three kinds of information are presented:
Aid Figures, New York Times news, and wikipedia
description.

Global Linked Data

This demo uses data from Dataset 311 on crime in the United States,
census.gov and UK recorded crime.It shows available information on crimes
in cities grouped by US countries and UK Territorial Police area.

Global Linked Data – Just Beginning

•  A spirit of competition and
collaboration

•  Contacts with US, EU etc

•  Beginning to compare and
contrast the catalogues

Oh no you can’t…

Loss of licensing revenue National security

Loss of control Complexity

Legal challenges Investment

Exposure Capacity building required

Procedural changes Authenticity and quality

Privacy Customer service

Oh yes we can…

More transparency More economic/social capital

what is going on? generates opportunities

More accountability More engagement

and is this acceptable? we can extend and improve

More localism More argument

because it matters to me, data for evidenced based
my family, my locale policy
