The Royal Mail PAF, that old Chestnut…

Tom Watson…MP for West Bromwich East, the UK’s first Parliamentary blogger, and critically, the cabinet office minister responsible for delivering on the Power Of Information report, recently noted interest in the issues surrounding access to the Royal Mail Postcode Address File (PAF); Tom was promptly informed it was an ‘old chestnut’, what on Earth could that mean?

PAF: That old Chestnut

I talked it over with my well informed friend at the council, who cast some light on the interaction between Local Government, the Royal Mail and the Ordnance Survey…


…local government has an inescapable business need to store data about a multitude of non-addressable objects (ATMs, bus shelters, you name it…they probably need it). Ten years ago, no such dataset existed, historically the old OS address products (AddressPoint etc.) only contained entities that received post, as they were all based on the Royal Mail PAF. To address this business need Local Government set about creating a National Land and Property Gazetteer (NLPG) because no dataset existed which met their needs. Now, here is the Chestnut, enter stage left, two government agencies tasked with delivering a Return on Investment\Capital Employed, and a fictional property developer…

Watson PLC decide to build some new properties. Having identified and procured a suitable site and decided what you would like to build the next step, by law, is to apply for Planning Permission from the appropriate local authority. As part of that process you are required to submit detailed, scaled drawings showing precisely what you are proposing to build and where you are proposing to build it. So… local government is always the first to know about new developments.

If you are granted Planning Permission then you are advised to contact the “Street Naming and Numbering Officer” of the Local Authority concerned to agree the addresses of your new properties with them. This is a statutory duty of local government that, legally, no-one else can do (The legislation under which this happens varies but it’s most often Sections 17-19 of the 1925 Public Health Act). If you’re building new streets the Local Authority name them and add them to the National Street Gazetteer. They also allocate the individual property numbers.

Now the daft bit; clearly the only organisation that can assign a postcode to new properties is Royal Mail as postcodes are their property (and exist solely for the purpose of facilitating the delivery of mail by Royal Mail). The Local Authority Street Naming and Numbering Officer therefore has to give their new addresses to Royal Mail for them to add the postcode and, if one is necessary, the post town. As soon as an address contains a postcode it becomes Royal Mail’s Intellectual Property as they own postcodes! They then pass the address to OS who geo-code it, link it to the OSMM TOID, stick it in Address Layer 2 and sell it!

The real choker for Local Government and the UK tax payer is that if Local Government wishes to use address data with postcodes in, which of course they have to, then they have to pay royalties to Royal Mail to do so! They are forced to spend taxpayers money “buying back” address data most of which they created in the first place!


…my friend at the council puts his spin on the process to underline his frustration, just as the man from the OS, or the woman from the Royal Mail might put their spin on the process to underline their frustration. But the real issue here is…this is the system working?! All organisations are doing a good job, working to direction from the government, and delivering their targets. However, this doesn’t disguise the fact that… millions of pounds of tax payers money is being spent in duplicating what should be a single, definite and accessible resource.

Mobile Phone tracking with a Nokia N95 & MWS

Another rainy weekend proved a good excuse to sit down and put some theory into practice…

When the rain comes, taken by VeVi @ Flickr.

The theory goes…take a GPS enabled mobile phone; some beta software from Nokia; a handful of HTML, Javascript and PHP goodness; and you have all the components for a dynamic tracking web service and mapping website?

Well, the theory works! I’ve put a demonstration together at the following link:

Mobile Phone Tracking with a Nokia N95 Demonstration

Given all the current hype regarding some telecomunications technology; I’m puzzled by the apparent lack of interest in the mobile web server. Sure, there are a few pieces to still fall into place, but if the mobile web server’s graduation from Nokia research labs, results in widespread deployment, it must have a profound impact on the web?

Tomorrow's Web...

What would you create with Public Information?

…the Power Of Information taskforce is asking that question; and is prepared to stump up £20,000 to take your idea to the next level! The reasoning behind the competition is to get an understanding of the data and information the government needs to share to move things forward. To get the competition underway they’ve just released some new government datasets; for example, a list of all 22,000 schools.

Their website to harvest ideas (showusabetterway.co.uk) has been up for just over a day and seems to be getting a terrific response, I ran the ideas to date through Wordle to get a flavour of the requests being made, here are the results:

Congratulations to the POI taskforce; it’s a great step forward for the Free Our Data campaign. So if you’ve got ideas, get over there and jot them down. I’ve thrown my hat in the ring with the suggestion of a Road Works API

Nokia Mobile Web Server - a game changer…

This post builds on a previous post from earlier in the week, when I gave mention to some Nokia\Apache software that runs as a mobile web server on my mobile phone (a Nokia N95). The first thing that jumped out was the architecture of the software, ‘software above the level of a single device’ as coined by Tim O’Reilly. Then Phil jumped in with a comment agreeing with O’Reilly that such software has the potential to simplify the user interface of devices with small screens, but there is more to this software. A Google blog search revealed Ricky Cadden asking the same question…”I think there’s some serious potential here [MWS], though I can’t quite put my finger on it”.

Mobile Web Server High Level Architecture

Here is one reason I think it’s a real game changer - it completely removes the necessity of a network operator?

The likes of Skype and Gizmo already threaten the network operators’ phone call revenues, with VOIP based services; the mobile web server goes further. Let’s assume all mobile phones run with a mobile web server and have access to a wireless internet connection. Now write a one sentence webpage and host it on your mobile web server; restrict permission to view that web page to your best pal; make a request against a web service, running on your friend’s mobile web server, that alerts them of the new page you’ve created; and essentially you’ve just sent a text message - but without the network operator.

Moreover, replacement of the 160 character text message is only the beginning, this is revolutionary technology and a whole host of innovative applications can be expected to follow. What form might they take?

If we do move to a situation where the world’s 3 billion mobile devices ship configured as web servers, it would represent at least a doubling in the size of the internet (if there is a suitable metric by which to make such a measurement). What is more, if recent trends continue, and phones are equipped with GPS, these new web servers will be location aware and mobile.
