Data FocusTourism == International Info Sharing

Tourism → Data FocusScratching the exchange surface:

mobile apps, websites, kiosks, print, open data, partners, ...flow underneath:

DATA (quality and readability)Content == KING!

Real life Data experienceQuality- historic errors- different sources, different

buy-ins- not solution: access rights

and input validation- missing solution: checks,

reports, workflow-support

Documentation- it means what it means,

no?- values over types

- different interpretations and nuances

- machines don’t

Real life data experienceignore, or be silent about it...

Quality.correctcompleteaccessiblereadablehuman languagemeaning

context == queen

Semantic WebFrom pages to concepts.

Hits → Meaning @Google

letters & words … make → a person! → dates → relations → works

→ & links to ever more meaningfull items

How so Linked Data?(almost) like linking web-pagesExtra annotation in (hidden) tags. (RDFa)“Graph” (network) Model of the world

subjects →relations →valuesUses “vocabularia” (~ ontology)Open structure for modelling. (~ web)

Universal meaningMeaning is pushed from a local level to universal uniqueness. Basic idea: use URI to “place” things

No longer: see the “hotel” over there, Sir?but: No way, bro, check out that http://purl.org/acco/ns#Accommodation

p.116 – Interesting point made on the Platypus — that when the Platypus was discovered, scientists said it was a paradox. But Pirsig’s point was it was never a paradox or an oddity. It didn’t make sense only to the scientists because they viewed the nature of animals according to their own classification, when nature did not have any.http://roughnotes.wordpress.com/2005/06/07/lila-an-inquiry-into-morals-robert-m-pirsig/

not: this is what you must saybut: if you use those words, then people will assume this meaning

TourVocA Standard for Touristic Data

What pain?●(repeating) integration costs●stability and predictability●enable digital players●focus on content and quality●common sense●semantisch web (seo/inovation)

Ambitioned results●exchange of information●and annotations, corrections, completions●feed solomo applications (mobile guides)

●harvesting●level the bar for more open ecosystem

(competition <> monopoly)

Data Exchange Standard? ✓ shared vocabulary

(interoperability, understanding what is said)

ㄨ (not) a shared database(control, ownership, storage)

What it is●Collaborative result (publishers, gov, devs)●International (neutral)●Extensible (OWA)●Machine-readable (clear meaning)●Language mostly vocabulary aspect

○spelling, syntax, grammar covered by lower layers●For Information about Toeristic Products

Inspiration?

Inspiration!

Terms & ConditionsOpen● no usage limitations● available to all stakeholders● transparant decission process● published

Tuned in on international webstandards

Make it happen through maximum adoption and real use
