Mashup Ecosystem

  1. innovation in the programmable web characterizing the mashup ecosystem Shuli Yu ‐ Singapore Management University  for Mashups ’08 @ ICSOC
  2. is  made of… + integrate
  3. is  made of… API + integrate Mashup API registered in and these are 
  4. the
  5. m ashup
  6. s napshot s APIs Network intervals : th @ 6 mon 007 to Dec 2 Dec 2005 m
  7. m API m m API API m m API 2‐mode network
  8. m API m m API API m m API mashup  ecosystem
  9. m API m m API API m m API 2664 mashups594 APIs
  10. what are the characteristics? m API m m API API m m API growth structure patterns 
  11. growth... mashups per month 20 APIs per month
  12. apis ranked
  13. apis ranked top 20 APIs
  14. top 20 APIs
  15. power law
  16. long
  17. Chris Anderson (2004): The Long Tail, Wired
  18. Kalevi Kilkki (2007):  A practical  model for analyzing long tails, First Monday share of total volume  total volume covered by objects up to  rank x factor that defines the form the number of objects  that cover half of the  whole volume
  19. pareto rule 20% of the causes result in of the effects
  20. pareto rule? 20% of top APIs have created of the mashups
  21. another observation… 51% of all APIs have no mashups >4 mashups 3 mashups 0 mashups 2 mashups 1 mashup
  22. 18% 4% 8% 15% 51% >4  3 2 1 0 mashups long

  32. API Tier 2:  Social/Community,  API Tier 1:  Search Google  popular APIs Many  Maps API Tier 3:  Feeds, blogging, online  retail, music, video    Less popular APIs
  33. keystone
  34. keystones business strategy: create and (2) share value (1)  by creating  platform services, tools or technologies  that offer solutions to others Iansiti and Levien (2004): Strategy as ecology
  35. platform APIs  mapping, search, community  data APIs  news, pictures, videos, music, shopping
  36. so… what  matters? type of service a mashup provides  affects its compatibility  others  with
  37. so… what else could matter? existing popularity time (age) rating  security licensing model protocols and data formats
  38. regressions time series analysis
  39. what makes an API  successful? how to determine what role and  position in the network is most  appropriate? to think about.
  40. and many thanks, also, to Jason Woodard – John Musser – Darshan Santani
