In this article I am going to introduce you to a business case for Linked Open Data from a project we are doing for Abu Dhabi Municipality and the Department of Municipal Affairs in the Emirate of Abu Dhabi.

In all probability, you know Linked Data equally well or better than myself, I will therefore not spend much time on describing technology but emphasize how Linked Open Data for addressing poses tangible economic and efficiency benefits in the day-to-day operation of Abu Dhabi municipality, covering the agenda items displayed on the screen.

I realize that the word municipality generally doesn’t bode well for the entertainment value of a speech. The word fills the mind with the color grey – and any bright or hopeful emotions one might have had are suddenly extinguished.

This was also the expectation I had when I boarded a plane to Abu Dhabi eight years ago to start working on a project to implement a new street addressing system there.

I had until then never heard of anyone in polite society successfully utilizing the phrase ‘I work for the municipality’ without the second party displaying notable interest in terminating the conversation at the earliest possible occasion.

Yet, when telling someone in Abu Dhabi that I was going to do a project for “the Municipality”, they were much to my surprise visibly impressed.

Air escaped their mouths, but it wasn’t the customary yawn. It was more along the lines of a ‘wow’. The municipality was powerful. The municipality was known. The municipality was respected.

But I digress, and though you will find that a principal component of this presentation consists of digression, let me temporarily, albeit momentarily, get back on topic…

It is the custom of every presenter who speaks of the many virtues of Linked Open Data to include this graph as at least one of their slides.

In order to comply with the genre, I am not going to make any exception to this rule.

However, my reason for including it is to use it as a backdrop for this…

I beg your apology for this unprovoked attack on the center of the Linked Open Data graph – but the thing is, in terms of direct, demonstrable economic impact, there are other registries that hold greater promise, than linking of business data to DBpedia.

Another thing I’d like to point out is that it is easy to get intoxicated by boxes and arrows – and forget that the true value of Linked Open Data relies not so much on the link itself as it does on what you link FROM and what you link TO.

I do not know how familiar you are with the United Arab Emirates. Likely you are acquainted with Dubai and their ceaseless efforts to build stuff that is tall, deep, wide, first, largest or in any other way stretching the definition of some superlative.

You may imagine elegant white tunics, expensive cars, oil, gold and infinite wealth.

There are elements of this stereotype that hold true. Yet, after living in the country for seven years, I feel compelled to add to that the Emiratis also are ordinary people in the best possible meaning of the word ordinary, they are wonderful, gracious hosts and overall an interesting, remarkable and capable people.

I am going to introduce Abu Dhabi by turning back the clock 60 years and give you an idea of what was then Abu Dhabi city.

The important thing to realize about that time is not that the Gulf was a largely undeveloped economy, consisting of palm frond settlements, the off fortification and pre A/C climate conditions.

The important thing to understand is how fast society on the Arabian Peninsula has changed in the span of 60 years compared to here in Europe.

With the discovery of oil, the Emiratis came into possession of significant purchasing power. They wanted to use this power to build a nation.

And build they did.

A lot of stuff – and incredibly fast.

Today, Abu Dhabi is a modern city that outshines many, perhaps most cities, in terms of the amount of concrete and glass edifices. Its skyline calls for comparison with the cityscapes of New York, Hong Kong and Singapore.

Yet, working fast is not without its perils.

We have all experienced the moments when, after sitting down to relax after a hard days work, we are suddenly seized by the uncomfortable feeling that there is something essential that we have forgotten to do.

For the people who built Abu Dhabi, one of these moments came when the city outgrew the size where it was possible to describe locations by referencing landmarks – They realized that it probably would have been good to have an addressing system.

You cannot use this oversight against the Emiratis.

When you try to catch up with contenders who have a 500 years head start on you – and succeed in overtaking them within 45 years, it is forgivable to miss a few things along the way.

An address is one of those things that people could not care less about. Unless, that is, they do not have one.

At that moment a number of problems manifest themselves.

• How to tell the plumber where you live as water is pouring out of your wall?
• What do you to tell the taxi driver when your house is not in front of a well-known land mark?
• How do you order a pizza?

The oversight was not principally the Emiratis fault. The Emiratis paid good money, perhaps too good money, for “first class international advisors”.

The thing with “first class international advisors” is that more often than not, they do not understand Arabic, nor do they understand the customs and culture of the local environment. Upon my first arrival, I regret to say that I was no exception to this rule.

Whatever the project may be, first class international advisors often try to import an undigested, and expensive concept, created for a different social and cultural setting, from Europe, from Australia or from the United States.

For, how could anyone aspire to achieve excellence by any other means than by imitating “us” in the “Western World”, who by our own BBC and CNN definition are excellent?

Given this premise, it is easier to understand why the first attempt at addressing Abu Dhabi in the 1980s turned out a bit awkward.

In recognition of the melting pot of different languages and cultures that co-exist in Abu Dhabi, taking locals, white-collar and blue-collar workers as one, the first class international advisors thought street names to be too difficult for people. It was even put forward that text of any kind might be too difficult, since many drivers could not read.

While this sounded preposterous, a quick glance at the traffic accident statistics suggest that they may have been on to something.

While the Arabic alphabet is beautiful, it poses a great challenge to someone brought up with Latin letters. The “Arabic numerals”, however, look a great deal more familiar to us. It was therefore the idea of the first addressing project in Abu Dhabi to use only numbers for addressing the city.

And they did in truth use numbers.

They used a lot of them.

So many, in fact, that to identify a single house anywhere in the city it was necessary to know up to 11 digits in a particular sequence without any form of error tolerance lest you end up in a completely different part of the city than where you intended.

The first few digits represented a zone, the next few digits a sector, the third group of digits a street and finally a building number followed by an extra, unused digit – that was reserved for an unspecified future requirement.

It was, in short, an “intelligent” address.

This is interesting, as the problem of “intelligence” is the same that we face in Linked Data, when we are trying to agree on persistent URI schemes.

Should they be intelligent and unique or should they simply be unique.

Personally, I belong to the school of thought that believes that anyone contemplating intelligent persistent identifiers ought to be beaten with a stick.

However, in the absence of a legal instrument to sanction stick beating for URI related crimes, I have had to resort to simply repeat my warnings.

I speak from experience. Bad experience.

Identifiers are not to be read as a book. However, because the principal use of persistent URIs in the scientific community is discussing single concept graphs on projector screens – we have an urge to understand what the URI we see up there on the screen means.

However, once systems become operational with proverbial “tons of data” in them, the persistent URIs are used by systems for systems and their human readability is no longer an issue.

For the exact same reason, I find that addressing ought to be intelligent because the end-user is a human.

This was where the first addressing system in Abu Dhabi was flawed; it consisted exclusively of numbers.

Sequences of more than five numbers in a row are not so easy to memorize– and memorize people must – if addresses shall be useful to them.

15 years ago, we had the capacity to remember, with some degree of accuracy, the phone numbers of our close family and a few friends. Yet, the era still gave rise to the universally understood phrase “wrong number”.

That is because numbers are not particularly good for memory recall.

This is where street names come into play, particularly if people are made aware of their meaning and can form associations to the meaning, not just the sound. When introducing meaning, however, we stumble across the first obstacle to successful street name based addressing.

People are passionate about names.

More specifically, people are passionate against some names – and for others.

Try to rename a street anywhere in the world and you spark debate in the media as you may see from the samples I presently show on the screen.

Try to introduce 10 000 new street names into a city within the span of 2-3 years and you have created yourself a very difficult task indeed.

I can say with my hand on my darkened consultant’s heart, that no institution that I have ever worked with, and I’ve worked with a good few, have ever shown such democratic care for what the citizens think as Abu Dhabi.

Consensus is always the preferred way forward – rather than rejections based on majority votes or technical assessments.

An appeals process that permit citizens to react to and request name changes is put into place – and practiced rigorously. This reminds me of a particularly entertaining street renaming process that took place in Brussels, more than 200 years ago and that you can see on the screen right now.

The use of the address for locating people and delivery points for goods and services means that addresses are very important for linking business data.

• Make a purchase and your living and shopping pattern is mapped through the data that are recorded from your consumer loyalty card and your credit card
• Take up a cable TV-subscription, order a taxi – or a pizza. They all ask for your address, they all use it and they all store

Thus, what commercial viability is concerned, addresses pose a far greater value proposition as a central linking registry for Linked Data than for an example DBpedia does.

However, we cannot in good conscience link to a street name and a building number in Linked Data – we need persistent URIs.

I think it is appropriate to say that we stumbled over Linked Data in the Abu Dhabi project. The original idea was to provide additional way finding information for people based on embedding a QR-code with a link to a downloadable app on about 50 information boards at key locations throughout the city.

Simultaneously, there was a need for individually identifying all the signs in the city for a sign maintenance system. All signs are owned and maintained by the government and it is necessary to track these assets with respect to maintenance state and life-cycle management.

In the end, we decided to equip ALL signs in Abu Dhabi with an individual QR-code, more than 80 000 in number.

Then came the question that led us to Linked Data: what do we put in the QR-code?

We could encode a unique number or an alphanumeric string – but then any client application would have to be aware of the domain in which the unique value would be valid. However, if we encoded a URL, the client application would instantly know what to do about the identifier, could open a web browser and load the corresponding content.

This is where our GIS data models converged with Linked Open Data. The public information behind the URL was not a strong enough business case in itself. We needed to open up something to the service provider and business community.

We let the URL produce different results depending on how it is being accessed in accordance with good practice for dereferencing of persistent URIs.

For a business-to-business application, requesting XML or JSON it acts as a web service returning a well-defined format that can be used to populate lookup-boxes in electronic forms.

For a business-to-consumer scenario where a citizen scans the QR-code on his regular, Internet connected smart phone, it serves up a web page with information about the address.

Projector screens are not particularly good for scanning QR-codes – but if you were to do so, you would see that the persistent URI used for addresses in Abu Dhabi also qualifies for a thorough stick beating.

I am sad to say, that it is intelligent, with all the problems that that encumbers.

Still, it is unique.

While the addressing registry constitute Linked Open Data, much of the value-added business data constitute Linked Private Data.

If all data are open it is likely that the data are not sensitive or critical; where there are no critical data there is limited willingness to pay; where there is limited willingness to pay – there is limited business.

Even for the isolated purpose of managing the signs, using persistent URIs to identify individual signs is cost-neutral.

However, the real value proposition for the residents of Abu Dhabi – and for the service providers – lie in the efficient identification and verification of locations across all government and private sector entities that offer services to residents and visitors.

For the past year, many working meetings have been arranged with all utility service providers and government agencies that deal with location information in the Abu Dhabi; the purpose being to have them use the addressing data as their location reference frame for their customer relationship management. Parties who will adopt the addressing system for CRM include

• The National Identity Authority
• The statistics center and census authority
• The food and health safety authorities
• Water and electricity authority
• The gas companies
• The cable-TV and internet providers
• The taxi and delivery companies

The message to take away from this talk is that the publishing of key registries such as addresses, property identifiers and building identifiers will be important catalysts to foster further business value from Linked Open Data both in Abu Dhabi and in the rest of the world.

Therefore, to any custodians of such registries. Get them on the air as soon as you can. Please feel free to come and visit us in Abu Dhabi or Norway if you’d like to learn more.

I have great expectation for the future convergence between Linked Open Data and GIS technologies.

At the local airport, a grumpy check-in attendant is registering passengers for the morning flight to Bergen and Oslo, before urging the customers on to the even grumpier security control attendants.

A passenger decides the gloom of the situation calls for a wee bit of cheering up, and, as he approaches the security guard, asks “have you had my bombs checked yet, sir?” – upon which the desired reaction, a smile, make it’s absence painfully apparent.

Instead of the envisaged upward mood-swing, the security guard pushes his alarm button, triggering a terrorism alert, calling in the police, while simultaneously detaining the well-meaning passenger, with the ill-chosen joke, for questioning – denying him to board the plane.

At the same airport, a few years ago, a friend of mine was allowed to carry an ice axe as hand-luggage, on the sole condition that he promised not to hijack the plane.

It’s a truly wonderful world!

• Google reports “about 25 500 results” for the query “I hate Facebook”
• Google reports “about 22 200 results” for the query “I love Facebook”

Those in their right mind, who hate, still are in the lead, but the margin is shrinking towards the social-networking-addicts. Be strong brethren: We shall overcome! (We must!)

Each year since 1985
Each year since 1985, the editors of THE FUTURIST have selected the most thought-provoking ideas and forecasts appearing in the magazine. Over the years, Outlook has spotlighted the emergence of such epochal developments as the Internet, virtual reality, and the end of the Cold War.

The Bishops Meeting, part of the management of the Church of Norway, has decided to alter future translations of the Holy Bible into Norwegian by excluding the word “tukt” (Norwegian for punishment/torment). The decision was made unanimously. It doesn’t say if God was consulted on the matter, but we must assume that He, like most Norwegians, is a democrat and will yield to the oppinion of the majority.

The background for “overruling” the word of God is a request from the Norwegian Commissioner for Children in the interest of avoiding child abuse from being exercised in the name of Christianity. A worthy cause!

It is however interesting that the Church of Norway sees the Holy Bible, and thus the word of God, as being subject to democracy. Many Norwegians will claim to be “personal Christians”, believing in their own custom subset of the Holy Bible, omitting those parts that are either too difficult (resurrection) or to uncomfortable (sin/punishment) to deal with.

Though “personal Christians” claim to believe in God, it remains to be seen whether God actually believes in them! We shall never know, as once they find out they probably won’t be blogging any more!

Back in May I posted my Google search results for people’s feelings towards Facebook following a heated discussion with an old friend. Just to test out the use of Google as a poll tool I decided to repeat the search today – here are the results:

• 1 – 10 of about 11 200 for “i love facebook” on August 7th against 543 (+10 657) on May 6th.
• 1 – 10 of about 24 300 for “i hate facebook” on August 7th against 8 470 (+15 830) on May 6th.

My (somewhat inscientific) conclusion is that those who are angry are more likely to write about it immediately whereas those who didn’t realise the magnitude of their mistake in time are more likely to come out and try to defend it as time goes by!

Those who have had the pleasure of visiting Rio de Janeiro have inevitably also seen the favelas, shanty towns, a few blocks off of the citys besung (and in my view vastly overrated) beaches. Norwegians think of favelas as something that we do not have in “our” country. However, upon travelling past Gol in Hallingdal you will encounter this view which I think resemble very closely a Brazilian favela.

There is a difference though: the inhabitants of the favelas live simple because they are forced to do so – we do because we want to!

Within a span of three measly weeks I have managed to have one camera stolen and another one lost! Maybe it is a sign that I ought to stop taking photos?

If by any chance you’ve found a Canon IXUS 400 in the international departures area at Oslo airport Gardermoen, I would be much obliged if you would give it back to me. But I suppose that’s a lost cause.

However, this could be an appropriate moment to introduce the first outputs from my very, very cheap replacement camera bought at Corsica last week where companions Harald, Øyvind and I went for spring holidays.

You may be surprised to read this letter as we haven’t formally been introduced to oneanother. However, as you know we did meet briefly at Dublin Airport Sunday, 13th of May 2007. I, a law abiding citizen and amateur photographer, was there with my camera. You, a bastard, were there making an exhibit of your liberal attitude towards criminal law. I left without my camera, you, sadly, did not!

I write this letter to express my worst wishes for your future. In fact, I curse you and hope you will be badly injured in a one-in-a-million exploding-camera-accident and choke on the lens until you turn an unhealthy shade of blue. If this scenario doesn’t sound too pleasant I would alternatively settle for getting the camera back. How about you give it to me eh?

Oh, and in the not entirely unlikely event that you acquired more than one camera in this manner on that date, mine is a Canon EOS 350D with a SIGMA 18-125mm lens neatly tucked away in forest-green Lowepro camera bag.

With absolutely no regards
