The document discusses legislation as data and linked data. It notes that legislation contains structured data like definitions, changes, duties, and offenses that can be represented semantically using URIs, RDF, and linked data principles. This allows different pieces of legislation and related concepts and facts to be linked together to enable new types of analyses. For example, it could link changes to legislation to conviction rate statistics. Representing legislation as linked open data follows the model of open source software and could create a new "impossible public good" by openly sharing high-quality legal information.
2. • “The acceptance of the rule of law as a constitutional
principle requires that a citizen, before committing himself to
any course of action, should be able to know in advance
what are the legal principles which flow from it”
– Lord Diplock, House of Lords, 1975
• “The law must be adequately accessible”
– European Court of Human Rights

3. The web has changed who is accessing legislation and
why, just as much as it has changed access to healthcare
information

7. Legislation as data
• Three considerations for legislation as data
o Typographic layout
o Versioning / changes over time
o Semantics
• Semantic representation using RDF and Linked Data
o URIs for things
o RDF data model
o subject - property - object
• Requires granular URIs to name things
o Identifier
o Document
o Representation

8. Foundations - naming things
• If you visit legislation.gov.uk you will see we have taken
great care with naming things

14. Legislation as data, legislation as code
• Legislation as data – the information contained in legislation
can be accessed and used by computer programs
• Legislation as code – legislation is (or becomes) a set of
processing instructions for a computer to follow

16. Data
• All the information on legislation.gov.uk is available as open

19. Henry Maudslay (1771–1831)
He also developed the first industrially
practical screw-cutting lathe in 1800, allowing
standardisation of screw thread sizes for the
first time. This allowed the concept of
interchangeability (a idea that was already
taking hold) to be practically applied to nuts
and bolts. Before this, all nuts and bolts had
to be made as matching pairs only. This
meant that when machines were
disassembled, careful account had to be kept
of the matching nuts and bolts ready for when
reassembly took place.

20. Documents of the Semantic Web
Ever since the start Data
developments, one of the issues was how to make
various types of data available on the Semantic Web
for, eg, further integration. Technically, this means
making the data available in RDF. One approach is to
encode the RDF data in one of its serialization formats,
ie, RDF/XML or Turtle, but that approach does not
really scale. Interfaces to databases are being
developed that can, for example, provide on-the-fly
conversion of data into RDF, often via SPARQL
endpoints. Automatic or semi-automatic conversions
exist for a number of other formats. In general it has
been recognized that one should not look for one
specific approach; rather, different types of data on the
Web require their own, data-specific way of expressing
Unstructured text Structured data
HTML web pages, CSV files, RDF
PDF documents Linked Data

Section 12 (4) amends the Charities Act 1993,
inserting some words into this Act.

25. Bringing into force the Act
Sections 15 to 20 come into force
immediately when the Act is passed
But what about Section 12???

26. So, “A” changes “B” when “C” says so
So the timing for the rest of the Act coming into force
is left open for the Secretary of State to decide…

• Identifier
o http://www.legislation.gov.uk/id/{type}/{year}/{number}/section/{number}
o eg http://www.legislation.gov.uk/id/ukpga/2010/32/section/12/4
• Document
o http://www.legislation.gov.uk/{type}/{year}/{number}/section/{number}
o eg http://www.legislation.gov.uk/ukpga/2010/32/section/12#section-12-4
• Representations
o /data.xml

47. Not all information is equal
• Publishing digital information changes the form of the
content
• The facts on which £ billions turn or that impact on people’s
lives require different treatment from the ephemeral – not
least to ensure the integrity of the public record
• Who is making information available, by what right, what
processes has it been subject to, become key questions
• Increasingly important to express provenance for high-end
sources of information, such as legislation.gov.uk

52. “The impossible public good”?
• Large and complex systems
• Enabled by the internet
• Two elements,
o a system of sustainable value creation
o a system of governance
holds together a community of producers
• Distributed property rights, eg the GNU Public
Licence (GPL)

54. Open Government Data: a new impossible
public good?

• Enabled by the internet

• Distributed property rights enabled by the Open
Government Licence

55. Expert Participation
• Make the data available maximise, encourage and support
re-use
• Inside-out, transform internal processes, systems and tools
to external ones
• Retain what adds value – practice, process and control
• Invite expert participation from other parts of government,
businesses, academics and individuals
• Open data enables investment
57. Legislation data as a public good
• Old world: commercially licence the data to bring in the
resources needed to create and maintain high quality
information that is easy to re-use
• New world: open the data and enable participation, to
bring in the resources needed to create and maintain high
quality information that is easy to re-use
Reasons why Right to know if our liberty is going to be taken away, by doing something or not doing something Right to know, our civil rights and duties Economic benefit Types of law in the UK Statute law European law Judge made law We lack a carefully drafted legal code, as they have in Germany, France, Italy Our statute book is a complicated place – it requires effort to tame it

Examples of people talking VERY specifically about pieces of legislation. All the links are shortened links to legislation.gov.uk, which because of our URIs, encourages people to be precise when talking about legislation. Here Ben Parsons is discussing the rights of the police in relation to public order and a May Day event in Brighton.

Points to note Substantial portion of new regulation does come from Europe Impact of devolution to Wales (the Welsh Government bubbles – including a substantial amount of the new EU legislation) Defra and BIS have been the large implementors of new EU driven regulations
