questions on use of public transport

use of public transport data other than intended by the operator - showing a visualization of
the rains in real-time

show travel time maps - like on http://www.mysociety.org/2006/travel-time-maps/ - an
experiment from the local.ch labs to answer local search based on public transport distance.

http://leumund.ch/2008/business/ohne-tram-nichts-los/
the importance of open data - my case for public transport - people expect good integration
and mash-up-ability (=getting more people using public transport)

there is not public API to public transport data in switzerland - nether it is easy to integrate
the online timetable at sbb.ch into another website/blog/mail... making these data better
availabe would create a ecosystem of innovative solution that ultimately push for better use
of public transport.

The UN is doing it better - they provide a central portal to get open data from various places
inside the organization. The user can choose different formats to reuse the data. Missing is a
live API to get the data (e.g. for mash-up)

RSS
Really Simple Syndication
OPML
Outline Processor Markup Language
Two standards that are established in the data syndication arena - explaining history and
current use of RSS/Atom and OPML. If data needs to be provided to an unknown receiver - we
should always check if we can use well known open standards as base - that makes the
integration easier on the receiving end.

and the end of the data - it’s all about personal productivity - we (as human) need to
juggling a lot of tasks.. - technology that help us to improve that has great chances to get
adopted. Want to focus on personal productivity in the new few examples..

ICS
How to get data from a website into our real-time -> calendar/address book/mobile phone...
- back to public transport - showing sbb.ch example - they added ICS export last year.. a
great extension - finally a semantic way reuse the data on the screen..
I used to do a photo of the screen with my mobile phone in order to reuse the data on-the-
go!

instead of photo/ics... - we could use different encoding methodes to transport data over the
screen to different device - like mobile phone - example with QR Code

Reuse Web Data http://tel.local.ch/
Do Microformats Demo in Firefox 3 and Operator - transport data from website to other
website or desktop..

http://dbpedia.org
http://wikipedia.aksw.org/index.php?qid=13
Show example how people try hard to extract semantics out wikipedia.

Microformats RDF
Resource Description Framework
Explain the Semantic Web “light”

Digital Identity - we start to collect a lot of data about ourselves on the web (various websites
of choice) - but these data are not connected

Nokia Zimbra iPod
N95 Mail Server Classic
Mac Book .Mac Mac Mini
Pro Server @ Home
Sync Adressen, Events, ...
in the proprietari world - showing example of Apple iSync - it works great.. we can sync data
between different systems and reuse them easily.. - but what is with the web?

OAuth
App-to-app Authentication
explain the base for data portability of privat data is authentication and security - spotlight
on two standards..

http://www.wishlistr.com/
show an OpenID demo and explain how it works.. - SSO, decentralized, attribute exchange...

Disclaimer: Facebook does NOT use OAuth!
Website-zu-Website Login!
show use case for OAuth - get data from one website into another one.. without leaving the
username and password on the site that wants the data..

Desktop zu Web - Beispiel: jingproject.com
Disclaimer: Flickr does NOT use OAuth!
show example between desktop app and website..

Social Graph

Photo: Gustavo
explain the experiments to extract the social graph from the “normal” web... - using links
(with Microformats)..

Photo: David Hogan
but what about the rights? - the law? using data is always connected to what I’m allowed to
do with them...

Original auf Flickr
Weiterverwendung
explain the Flickr picture reuse via Creative Commons.. - my photo that appears on two
football sites...

CC-BY-NC-SA-2.0
showing another example - explaining the idea of creative commons..

Tipp
http://flickr.com/search/advanced/
show the Flickr Advance search - explain how I’m search pictures for the presentations..

Open licenses do not stop in the web - they even find their way into very commercial spaces
- like the music industry - explain the example from NIN
