Anden video går tæt ind på området omkring Soho. Soho er det område i London, der sendes flest geotagget tweets fra folks Twitter konti. Dermed vises Soho som et kæmpe bjerg. Det er en slags DEM (digital elevation model) baseret på virtuelle klynger af geodata og ikke baseret på den virkelig verdens fysik.

Nogen, der er friske på at lave en Københavner version? Det er virkelig blærerøvs visualiseringer CASA tit disker op med, men på den gode fede måde.

Har dronning Margrethe fået nyt sommerhus? #osmsjov http://osm.org/go/0NXpeVsJK–

Hvor der så er et link i beskeden til et sjovt, underfundigt og sært navn på en bygning fra Danmark, der er blevet kortlagt i OpenStreetMap. For at følge med i den kommende tid af, hvad der kommer/bliver fundet af nye steder, så benyttes #osmsjov som hashtag. Du kan også følge mig på Twitter under navnet “@neogeografen“.

Mit ovenstående eksempel fører til en bygning, der hedder Daisy Hill som ligger oppe ved Espergærde.

Du kan også deltage i denne geotainment leg på Twitter. Så send en besked ud med hashtag #osmsjov og så det direkte OpenStreetMap link til stedet. Jeg vil så på et tidspunkt samle alle indsendt bidrag sammen og visualisere. Så kan du finde stedet og evt. til næste sommer tage fotos af dig selv foran et af disse sjove, underfundige og sære bygningsnavne.

Da billederne er i et stort format og fylder mere end skærmstørrelsen, de fleste har tilrådighed, så har jeg taget et par af de gode billeder og kørt igennem CASAs Google Maps Image Cutter. Billederne er så skåret op i 317 mindre billeder a 256×256 pixels størrelse. Derved kan du zoome rundt lettere og se alle deltaljer.

Det første billede viser Douglas H. Wheelock forlade trykkammeret og bevæge sig ud på rumvandringen.

Det andet billede viser Douglas i arbejde. Bemærk, robotarmen han er spændt fast på.

Det sidste billede er et natbillede (natten varer 45 minutter på rumstationen), hvor hovedlampe er nødvendigt.

Hvis du interesser dig for rumfart, så er Twitterkonto @Astro_Wheels helt oplagt at følge.

Du ser hermed et højdekort baseret på antal tweets i byerne (data fra de indsamlede byer). Nedenstående interaktive topografisk kort viser New York med en radius af 30 km fra centrum. Prøv at zoome rundt og se hvilke områder af New York, der især sendes tweets fra (stor udgave her)

De andre interaktive topografiske twitterkort i fuld størrelse kan ses ved klik på et af nedenstående links

• London
• Paris
• München

Sådanne geografiske visualiseringer kan fortælle en del om first movers (hvilket jeg mener, at brugerne af Twitter stadigvæk er) bevægelser gennem byerne. Hvor de holder til, bor og bevæger sig rundt i det urbane rum med deres mobile gadgets og computere. Gad vide hvordan et Københavnerkort ville se ud?

Hattip til Google Maps Mania

På Google Earth kortet i videoen ses på højden af ikon-markørerne, hvor mange tweets der er blevet sendt fra det område af London. Nogle områder af London er Twitter skyen tættere end andre. Jeg ser frem til, at CASA begynder at lave demografiske analyser af, hvor bor der mange folk, der benytter Twitter i London (eller fra de andre 11 byer CASA samler tweets ind fra).

(klik evt. for fuld skærm af YouTube video)

Så hvis du er Manchester United fan, så skal du i dine tweets i morgen under kampen skrive “#CCF10 #manutd noget tekst

“, og hvis du er Aston Villa fan så skal du benytte følgende “#CCF10 #villa noget tekst

“. Bemærk at # tegnet er et såkaldt hashtag, der gør at Tweet-o-Meter kan opfange den fodboldsamtale som finder af sted.

Hvis fans bor i og samt benytter twitter under kampen fra Manchester eller Birmingham, så kan disse tillige sætte geolokation indstillinger i Twitter op. Derved vil Tweet-o-Meter (hvert minut) vise, hvilken af disse to byer der har den største tweets aktivitet. Gad vide, hvor mange Manchester United fans verden over der faker denne geolokalitet?

Under målerne er der også nogle grafer, der viser tweets aktiviteten.

Såvidt jeg kan forstå, så vil CASA smide alle disse tweets ind i en database, så forskere kan analysere hvad snakker fodboldfans egentligt om på Twitter under en kamp. Jeg synes, det er ganske interessant eksperiment Carling Cup og CASA har gang i.

Jeg har før skrevet om CASAs Tweet-o-Meter, hvor det er 12 byer verden over de laver tweets analyser på.

Carling Cups brug af Tweet-o-Meter via Digital Urban.

Nu er det ikke kun sjov og ballade, fordi man kan. Alle tweets eller nogle få dages 24 timers tweets bliver samlet op og lagt i en database af forskere fra det engelske projekt NeISS (National e-Infrastructure for Social Simulation). Så disse forskere kan gå på datamining jagt.

Jeg kan fx forestille mig, at hvad hører folk af musik i storbyer verden over kan undersøges. På Twitter er det socialt vedtaget (blandt mange udover det engelske sprogområde), at man fx benytter hashtag #nowplaying når man angiver hvilken musik man lige nu lytter til. Så er relativt nemt (forudsat at folk i Tokyo, Oslo også benytter dette), at lave en undersøgelse af dette for forskerne. Fantasien sætter ingen grænser for hvad man kan datamine for at blive klogere på Twitters netdemografi og struktur. Et projekt jeg helt klart vil følge med i hvad de kommer frem til af resultater og undersøgelser.

Har du helt glemt M og hittet “Pop Muzik” ? så kan den genhøres nedenfor.

Prøv fx 90210 (det eneste postnummer i USA jeg kan i hovedet). Klik så på “Tweet”, nu åbner et nyt vindue sig og din Twitter konto er åbnet med en præfabrikeret besked til den senator for det indtastede postnummer. Du kan ændre i beskeden og klikke “Update”.

Hvis du går tilbage til “Tweet Your Senator“, så kan du på Google Maps til højre, se de seneste beskeder (tweets) fra det amerikanske folk til deres senatorer, om at de skal støtte Obamas sundhedsreform.

Dette er virkelig en smart måde at bruge Twitter som et led i en kampagne på.

Hvad værre er, at republikaneren Joe Barton bagefter twitter om det. Hvor han skriver, at der fik han vel nok skovlen under energiminister Steven Chu. øh nej, du er blevet til grin over hele verden i stedet for.

Transcript af dialogen fra video.

BARTON: Dr. Chu, I don’t want to leave you out. You’re our scientist. I have one simple question for you in the last six seconds. How did all the oil and gas get to Alaska and into the Arctic Ocean?

CHU: (Laughter.) This is a complicated story but oil and gas is the result of hundreds of millions of years of geology and in that time also the plates have moved around. And so, it’s a combination of where the sources of the oil and gas …

BARTON: Isn’t it obvious that at one time it was a lot warmer in Alaska and on the North Pole? It wasn’t a big pipeline that we’ve created from Texas and shipped it up there and put it under ground so we can now pump it up?

CHU: No, there are continental plates that have been drifting around throughout the geological ages.

BARTON: So it just drifted up there.

CHU: Uh…. That’s certainly what happened. It’s a result of things like that.

WAXMAN: The gentleman’s time has expired.

Opdatering – 22:40 – Det viser sig at Joe Barton også har en YouTube konto – hvor han (eller nok rettere spindoktor) har lagt videoklippet ud under titlen “Energy Secretary puzzled by simple question

Nu er jeg også glad fordi Twitter gør kraftigt brug af microformats. Dem du følger “Following” på Twitter er opmærket med hCard – samt har tilføjet rel=”contact” fra XFN i hyperlinket. Strømmen af maks. 140 tegns beskeder er opmærket med hAtom.

Jaiku bruger også microformats. Dine “Contacts” på Jaiku er opmærket i hCard og i hyperlinket benyttes rel=”contact” fra XFN. Jeg tror, at Twitter og Jaiku er de steder hvor flest danskere har produceret microformats uden at vide det var microformats der kører i baggrunden. Eller er der flere danskere med deres Flickr profil, som også er mærket op med hCard, som er vinderen af hvor flest danskerne har mødt microformats?

Bliver 2008 året hvor danskere webudviklere for alvor hopper med på microformats vognen? – Det kører lidt i tomgang med danske nyheder vedr. microformats.

[1] Søren: Welcome Brian. The microformats community quite often use this phrase “Designed for humans first and machines second”. How would you explain this concept for web developers and ordinary web users,who never have heard about microformats?

Brian: I like to talk about microformats as “semantic sugar”. Everyone can understand that adding a little bit of sugar to your food you make it taste better. Adding microformats into your HTML makes it “taste” a little better too!

The “Designed for humans first and machines second” is attempting to point out that microformats always take into consideration the publisher first. This means that things should be as easy as possible for the person writing the HTML. There will be factors of 10 more people publishing than writing parsers, so why make it easy to parse at the expense of the publishers? The other big thing this stresses is that data should be for humans, it should be in plain view – you should see it every day through the window of your web browser. Data that is only for machines tends not to be visible to humans in a meaningful way, so we forget about it, we never update it and next thing you know it is completely wrong!

[2]Søren: You are one of the co-authors of hCard, where did the genius idea came from regarding reusing the old vCard specification for hCard?

Brian: I already knew that my target was going to be vCard, so for me i was simply creating a vCard in HTML rather than XML or plain-text. Basically, a good programmer is lazy. It is always a good idea never to re-invent the wheel when ever possible. Using vCard properties for class values was a logical choice, with applications already supporting it, you instantly get inter-operability.

[3] Søren: First time I did a hCard and then pointed the URN for that web page with my hCard to your “GEO Microformats to XML” tool and a KML file started up my Google Earth, I was very impressed and felt that this were one of the more practical things to do with microformats. Later on, I have discovered that when showing new people microformats in action (on a FireFox browser with Operator) – Examples with hCard and maps (Google Maps, Yahoo Maps, Google Earth etc.) is the first thing they think is smart and usefully for them self. Do you have the same experience when you are talking at conferences, that examples with maps draws peoples attentions to microformats?

Brian: Certainly maps are something everyone can relate too. In my presentations I try to show at least one practical and one “far out” demonstration of microformats. Usually, i demo how to take an HTML page, upcoming.org or any other with an hCalendar, then convert that to an iCalendar file.

With the newest versions of Outlook and Apple’s iCal, you can “subscribe” to events. This means that as the HTML pages are updated, your calendar application gets those updates too. This tends to really impress an audience, because we have all probably missed a rescheduled meeting or event due to a rescheduling. HCalendar really scratches an itch that people have every day.

I also like to demo some crazy far out stuff too, just to get people’s minds thinking. Twitter, for example, marks up all your messages as hAtom entries. Each of these entries has a publication date, so there is no reason why it isn’t possible to extract the data and convert it to XML or JSON and have it loads into a timeline or other software. Now we can begin to see twitter posts in relation to each others time distance rather than just as a list.

[4] Søren: Speaking about the upcoming FireFox 3.0 (not talking about the version out now for testers) and the build in microformats detection feature – will this be the breaking point and the big step ahead for microformats? – so we maybe see a success for microformats like the one RSS/Atom have gone through?

Brian: I think having a microformats detection native to the browser will be a big benefit to adoption and awareness. RSS/Atom has exploded for lots of different reasons, but it has taken many, many years! Where I personally see microformats in the browser excelling, is on mobile devices. Imagine if the browser in your phone was microformats aware. Instead of trying to re-type an event using T9, it could be one-click, save to calendar, one-click, call this person, one-click, get directions to this place from where i am standing right now based on my lat/lon of my phone’s built in GPS unit.

If all things were equal between two websites, but one used microformats and the other didn’t, when on my phone i bet you know the one i’d pick!

For better or worse, the end-user doesn’t really care about microformats. If you look at the current Operator toolbar, it doesn’t mention the word “microformats” at all. It is all “action” based. Which i think is good. My parents don’t need to know what microformats are to be able to “save to address book”. The better a technology is, the less of it you see. To most people, FireFox 3 knowing that there are 3 events in a page will just be magic. To any good web developer,they will want to know “how do i get my pages to have those options appear” and will learn more about microformats.

My dream would be that microformats become so ubiquitous that you don´t need to announce that they are in your page, it is just expected. Much like making valid HTML, you shouldn’t be proud and announce to the world “My HTML validates”, because that should be a baseline. It is like telling the world “I brushed my teeth this morning”, so what – i hope you did. If we evangelize enough, microformats will just become part of the HTML you produce on a daily basis.

[5]Søren: I maintain a list over danish web sites which is using microformats (The list does not incl. “rel-tag” web sites). The list is very short. For me it seems like microformats is very unknown in Denmark at the moment. Do you think that microformats can have a some language barrier? I am thinking about ‘classes’ for example are all in english [ like class="street-address" i hCard etc.] So a danish, swedish or finish web developer might thinking what kind of benefits will I get from using english ‘class’ names in my markup? So will we end up with microformats in small countries/languages is only something a few hard core techies is doing?

Brian: Microformats are small re-usable pieces of information, so I´d hope there isn´t much to remember and the barrier to entry is low. HTML is already (for better or worse) in English, so you need to understand what a <p> and <strong> mean relative to Danish. This learning comes from information in your own language, but what you write in is ultimate English. This is why it is important for sites like microformats.dk, microform.at, microformats.biz and others to be localized so more people can learn about what class="street-address" means in their own language and culture, just like you needed to learn what <em> meant.

I don’t think this is a huge drawback for the interoperability. Everything is a trade-off so a unified language for describing things makes it easier to adopt globally so we all know we are talking about the same things. The people I feel sorry for are the British English speakers, it is their native language, but to them all the spelling is wrong!

[6] Søren: You have been an invited expert for the GRDDL working group at W3C. How does the folks at W3C looking at microformats in the picture of creating a more Semantic Web? I have seen that Tim Berners-Lee is quite positive about microformats – (like this twitter message from Tantek Çelik “Tim Berners-Lee just called the microformats wiki “a special holy place ”)

Brian: The W3C is a big organization, but all the people that i have met like microformats – both as an idea and a technology. Their main concern is that microformats can not solve everything, they only cover popular aspects such as People, Places, Events, Reviews and a few others. Whereas with W3C technologies, such as RDF a you can just about describe anything you want, but as with anything there are trade-offs.

Up until a few years ago, there were only two options, HTML and RDF. Two pretty far ends of the spectrum. HTML was for the browser and human eyes, whereas RDF was for machines (and can hurt human eyes if you look at it!).

In recent years we are filling in that spectrum between HTML and RDF. We have the more complex, but can describe anything markup in RDFa or eRDF, and the more lightweight microformats that are easier to implement but have limitations. Then there is POSH and GRDDL to also add and extract semantics. We now have more choices and can select the best tool for the best job on any given project.

I think, from the people i have talked too, that everyone agrees anything which gives more meaning to the web is a good thing. If it has enough structure, then it can be converted to other formats, RDF, RSS, Atom, etc. so that existing tools that people are familiar with can use, understand and act on the data. Microformats do this extraordinary well for very little costs, so it is very much a positive thing for the Semantic Web.

[7] Søren: At the moment you are quite interested in OpenID working together with microformats. Can you tell a little about what the idea is behind all this?

Brian: sure, OpenID is away to authenticate yourself and prove you are who you say you are. Microformats can work with this to further describe more about yourself. For instance, i have a profile page at claimid.com/briansuda with an hCard and i can say that is me, but you just have to take my word for it. ClaimID is also my OpenID provider, so i can also prove that page is me by passing an OpenID challenge response system (username and password). I should be the only one who can answer that username/password so you can trust that i control that page which i am claiming is me. It is a verified way to trust the microformatted data.

I also like using OpenID for lots of other stuff too. Friends of mine have blogs, but don´t want to list a full hCard to the general public. So for the world, you can get their hCard with only an FN and country-name, but for friends to authenticate themselves with OpenID they can see a full hCard with email, tel, adr, etc. So OpenID is a way to white-list friends to sensitive data.

OpenID is a really interesting open technology which compliments microformats well.

I thank Brian Suda for taking his time to answer some questions here at microformats.dk. I really liked the word “semantic sugar” Brian used above and will used from now on (in danish translation). If some danish readers out there are interested in microformats, we maybe could start a danish barcamp etc. Please feel free to contact me regarding microformats.
