What is a URI?  This is the question a colleague asked me yesterday.  Of course, he knew what it stood for (Uniform Resource Identifier), but he was asking what it was for and why they are interesting to government.  The initial answer is that it is essential for the idea of Linked Data, it is the process through which one bit of information is linked to another bit.  But I wanted to dig a bit deeper and explain the kinds of use of Linked Data that the government has in mind.

The Web is basically a document standard – a description of what constitutes a Web page, together with a process for describing it’s location (the URL) and so of linking from one to another.  When you do a Web search, for example using Google or Bing, then you get a list of documents in which the information you seek might be in. 

A URI enables a unique way to identify a particular bit of data inside the Web page, and so link one bit to another.  Thus it might be useful to distinguish London-the-place from the other London-the-places and from the several authors with surname London.  We can get some way towards this by intelligent contextual analysis, the approach that Microsoft, for example, told me they are taking.  This involves heavyweight data crunching using search technologies.  The URI approach is to identify something as distinctive,  for example, London the place in this particular geospatial location, and then give it a URI that others can use to refer to it to disambiguate it from all other occurrences of the concept or word.

This is the core idea of a URI, that a place, event, person, concept, document, or whatever can be given a unique identifier that others can use.  Of course you need to do something more than that, as Sir Tim Berners-Lee describes in his four steps:

1.  Use URIs as names for things
2. Use http URIs so that people can look up those names
3. When someone looks up a URI, provide useful information using the W3C standards (RDF, SPARQL)
4. Include links to other URIs so that they can discover more things

 I usually add one more:

5.  the provider of a set of URIs provides a Lookup service to take the object being named and provide a URI for it (i.e. the converse of 2.)

 So what would be useful for government to do?  One fruitful area to explore are those things that come and go, or move around, or change.  For example MPs get appointed to serve in HM Government and then move around.  Giving each MP a URI so that every time a press release reports their activities would be helpful, particularly as they are often described in different ways.  Clicking on a URI link could take you to a page of information about them – for example their biography, committees they serve on etc, or, with a little macro on the side, a set of relevant links about them.  And then there might be URIs for Departments.  They come and go – when were they in existence?  What were their responsibilities?  Is there archived content about them?  What is the current list of Departments? That kind of information we know would be useful to provide, as we get asked for them

Those are two examples of sets of URIs that government could usefully run:  the MP names, and the list of Departments.  Another might be the roles that comprise HMGovernment, i.e. the Ministers.  Clearly at local government level the set of Local Authorities would be one that would be useful, so that one person referring to a public body would know it was the same one that another called by a different name or abbreviation. 

The government has developed a draft standard for designing sets of URIs and we are now exploring what core sets of URIs it would  be useful to provide.  Let us know and we’ll see if we can do so.

This week has been one of conferences.  On Tuesday was the Public Sector Information annual conference .  It is amazing to think that it is just one year ago that, working with John Sheridan, I presented an overview of how data and structured information could be released using semantic web markup.  Since then London Gazette has been released in RDF/XML and people across government are busy implementing RDFa for consultations and in the public sector RDFa for jobs (for example Jobs Go Public’s local government jobs – LGJobs), the last two to be surfaced through Directgov.

More importantly, well underway is the Prime Minister’s drive for the release of data and creation of a single point of access (currently under development) through the appointment of Sir Tim Berners-Lee and Professor Nigel Shadbolt.   As the latter pointed out at the conference this is a single point of access not a single data base – the data will still sit in Departments, agencies and local government websites, but developers will be able to know what is available through some kind of searchable catalogue and get access to it.

He showed us a newspaper for a single postcode that had been demonstrated by some mash-up developers.  This included local data on crime, allotments, bus-stops and routes completely localised, along with lots of other useful information. We all liked it, because at present that data is something that each of us has to build up ourselves and we respond to it immediately as valuable.

The next day I spoke at the Public Sector Online annual conference organised by Kable.  The subject I was given was the cost of websites and I took the opportunity to remind all national and local government webbies that we need to be able to justify the expense of websites and demonstrate their value at this time of financial stringency.  In fact we have a great story to tell relative to many channels of communication, but I am guessing that the Finance Directors don’t yet always see that value and fund invest accordingly.

We’ve issued the standards on improving quality by measuring cost, usage and user satisfaction, following the Public Accounts Committee recommendations.  When these are reported people can start identifying lots of interesting aspects, answering the question, for example, of the value of the website channel to the nation.  Net value could be determined by the total online cost for satisfied minus unsatisfied users and subtracting the overall cost of provision. What we’d like to do is make the data available so that academics and economists can study this in more detail.

As a presenter it felt good to be getting email and comment from the audience floor which I was able to see shortly afterwards and makes a response.  The next conference on the Thursday was created to facilitate this – Government 2010.  Although I was invited to participate in person, I did so by logging in and watching the webstream. Lots of interesting thoughts, some of them inspired by Tom Steinberg’s contribution. 

It brought to mind a presentation from Martha Lane-Fox to COI on the Wednesday late afternoon, when she was asked the question about her experience in working in the public sector as the Champion for Digital Inclusion.  She responded that she had been really impressed by the calibre, intelligence and quality of the people she had met. 

It struck me that there are many talented expert e-communicators across government but hampered by the misperception that Web is IT.  There is an infrastructural element, but too often Web publishing is run as IT processes without the flexibility to change things day by day or initiate new trials or innovate.  We cannot even as I did in the old days, run two versions of a website in parallel and monitor what people do and continuously develop the more successful. 

It is like newspaper editors being unable to change the front page and only being able to stream new text into exactly the same shape of story, without being able to put in a major picture or give over the front page to a single story.  Newspapers and magazines would be very boring without that.  Likewise Web publishing should enable flexibility of all kinds of digital presentation and functionality.

Martha went on to say that public sector had many initiatives that needed joining up, not into a major programme, but under a banner that allowed lots to participate and encouraged a movement of activity adding up to more than the sum of the parts.  This would be a good description of what we want to do with the release of data and information for re-use.

A busy week of engagement that was encouraging as I and colleagues across government make the changes that support the directions sought.  What we do is often the road-building for the Ferraris (I wish!) and transport lorries that support trade to run upon, but without it they wouldn’t move.  So onto to improving quality of what we do in a measurable way, demonstrating its value to the nation, and structuring information for others to use and innovate.
