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.

Perhaps. While some more time might be required for thorough understanding of this comprehensive topic, the fact sheets are quite informative and would be useful as a reference for managers and people who have to related to GIS experts and who need a strategic overview rather than painstaking detail.

Download the fact sheet GIS Tutorial 101 in Ten Minutes and have a look for yourself.

• “I love Facebook” returned 3 890 000 results
• “I hate Facebook” returned 1 910 000 results

I believe it would have been healthier if the second number would have been larger – significantly larger!

The relative numbers appear to be the same:

• “I love Facebook” returned 969 000 hits
• “I hate Facebook” returned 1 110 000 hits

I am surprised – but very happy – to note that those hating Facebook are still in the lead.

On the negative side:

• Etihad was considerably less nice on this leg than I’ve become accustomed to from my previous flights with them travelling from Brussels to Abu Dhabi. Any basket is likely to have one rotten egg. Etihad’s seems to be the check-in attendant at Heathrow.
• The chairs at the conference venue were targeted more at efficient use of space rather than a comfortable sitting experience.
• The taxi drivers in London likes to rip me off.

On the positive side:

• The project kick-off was a success.
• The kick-off dinner

• 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!)

Best Anti-Piracy Ad Ever – Video

My doubts were however put to shame and I had some of the most enjoyable evenings out in a European city ever accompanied by good, solid German food. My thanks go out to Pål, chairman of the board of Avinet (and on other occasions excellent drinking pal), for urging me to come along.

Hotel California and the Hollywood Media Centre

The base of our operations was a hotel centrally located on West-Berlin’s Kurfurstendam. The hotel carried the rather dubious name of “Hotel California” which inevitably sprouted a large number of semi-identical and rather obvious jokes.

Despite the slowest elevator I have ever seen the hotel was very agreeable indeed. Good location and ok rooms. I never got to sample the breakfast but I was told, by those of my colleagues who managed to get up in the morning, that breakfast was good!

Naming the trip a “study trip” sadly required us to camouflage the party as a corporate learning event. This meant living though a few plenary session lectures before we could split up in more navigable units and get down to some real sight-drinking.

The “business-part” of the study trip took place at the Hollywood Media Center, a few blocks down the road from the hotel. Tacky wall displays informed visitors, whether they wanted to or not, about nearly six decades of film-making that hitherto had escaped most of us without our quality of life being poorer for it.

Kings Pub, a Russian on Ku’damm

Straight across the street from the hotel colleague Yngve and I found the best watering hole we had both encountered for a long, long time, Kings Pub, a hole-in-the-wall alcohol-consumers delight with room for no more than 12-15 people.

Kings Pub was run by Russian barmaid Irina on the two nights we were there. Irina knew how to charm pub guests into giving up their cash in exchange for dark beer and vodka. As a result we spent no less than € 100 each night on drink alone, which is much considering that one beer cost no more than € 3.

Warmly recommended, go there.

Afternoon breakfast at Hackescher Markt

For reasons unknown, I had agreed to aid Yngve in coming up with some entertainment for the gala-dinner of the study trip. Simultaneously I had been asked to give the final speech of the dinner, thanking the hosts.

The evenings being what they were time was suddenly running short if I was to both contribute to the entertainment and think a little about what to say in my speech. It was Sunday afternoon by the time we settled down at Hackescher Markt in East-Berlin to start writing.

Eating breakfast in the afternoon while watching street entertainment, drinking beer and writing comedy at once is far from unagreeable. Inspiration even came to us eventually.

Dinner at the roof-top restaurant in the Reichstag building

On Sunday night, the night before departure, our gala-dinner event was scheduled at the roof-top restaurant in the Reichstag-building, a truly magnificent location in the company of equally magnificent friends and colleagues.

Food was good, I got the biggest portion of Foie Gras I have ever seen. Either the goose was genetically manipulated or more than one had to die to fill my plate alone. The wine was better, borderline excellent, and complimented every course in an excellent way.

More surprisingly, entertainment was also good. Both the speeches and two additional “entertainment acts” plus an ingenious Asplan Viak-song were well-received. Even to the extent of praise.

As usual, the party didn’t stop in time for the following day to be an altogether good experience. I woke up with a start, hearing the bus I was meant to take to the airport 3 minutes later hum in an impatient way. 5 minutes later, in no fit state to travel, I was on my way to Schönefeld by bus.

Eight hours later I parked my car outside my house in Sogndal, walked in, crashed and fell asleep, fondly remembering the past days events.

This screen is obviously designed to be idiot-proof and reads in sequence these three sentences:

This utility updates the ROM image on your PDA phone
During the update the ROM update utility will :
– Allow you to update the ROM image on your PDA Phone

I read, I did and now I have a seemingly non-synchronizable Windows Mobile 6 phone in place of my old, fully functional Windows Mobile 5.

Progress!!!
