  • 2. Idea of Open DataOpen data is the ideathat certain data should befreely available to everyoneto use and republishas they wish, withoutrestrictions from copyright,patents or othermechanisms of control ** Auer, S. R.; Bizer, C.; Kobilarov, G.; Lehmann, J.; Cyganiak, R.; Ives, Z. (2007). "DBpedia: A Nucleus for aWeb of Open Data". The Semantic Web. Lecture Notes in Computer Science 4825. p. 722
  • 3. How to expose Open Data- Centralized or distributed system ?- Using most popular protocols and standards based onWWW or specific technologies ?- Exposition Web Services based on SOAP protocol or usingRESTful architecture style ?- Simple objects data representation: XML, JSON, TXT- Complex objects: files, XML+ files etc. (e.g. Maps)- Maybe should support Programming Language orientedobjects (e.g. Enterprise JavaBeans objects) ? and offer SDKpackets ?
  • 4. How to collect Open Data1) Data sources- Science- Government- Communication Service Providers2) Collection tools for societies- Web portals- Dedicated applications- Mobile applications3) Collection Tools from different sources: web portals,databases *,* Gawrysiak, Ryżko: Retrieval and Management of Scientific Information from Heterogeneous Sources2012 – Springer
  • 5. API – how does it works ?API – (Application Programming Interface) –component which allows developers in easy wayto integrate functionality one ICT system with 3rdparty systems and applications.API = „building blocks” for applications
  • 6. Why Open APIs are importantAccess via the Internet !We use the Web Services in RESTful. This interface mostly(for HTTP GET method) can be called using typhical webbrowser e.g: SMS sending: 515 086 915&msg=„test message”Easy to use !
  • 7. Why Open APIs are important“All teams will henceforth expose their data and functionalitythrough service interfaces. Anyone who doesn’t do this will befired. Thank you; have a nice day”.Jeff BezosCEO of Amazon, 2002Erik-de-Kroon_The-API-driven-culture-shift, SDP Summit, Rome 2012

  • 9. How to build interesting application ?-Combine different APIs from different sources-Add open data or collect open data-Attractive design-Rich fncionality-Low Hardware requirements-Low energy usage for mobile applications-Low price ;-)

  • 16. From open data to paid dataHow operator can expose their data:1 case – infrastructure topology- Open data: BTS localization and Cell ID- Paid data* - BTS localization and Cell ID + Base StationIdentity Code neithbor cell, BCCH (Broadcast ControlChannel id)2 case – CDR information- Open data aggregated and anonymised information abouttraffic between large cities- Paid data - anonymised information about traffic betweenBTSs* B.

  • 17. Summary-Open data is one of the key elements of the broadInternet ecosystem-Open Data and Open APIs mashup = source of newapplications and services-Observed trends in technologies : Web Services, RESTful,XML-Communication service providers should offer open andpaid data for developers and discover new business modelsfor sell them
