Decentralised entity registry “WikiReg”

  1. 1. Decentralised entity registry “WikiReg” Christophe Guéret November 5, 2012 1/8
  2. 2. Entity registry Associates some data to a unique identifier Example: DOI, DNS, … Typically, a (set) of central authority maintain andserve the data 2/8
  3. 3. Why decentralising ? Limit of central authorities Costly to scale Implies good connectivity Read-mostly, slow/risky updates Single points of failure Benefits of central authorities Easy to see where the data comes from Easy to control unique identifiers 3/8
  4. 4. Why decentralising ? In some contexts, deploying a central server ischallenging (if possible at all) Developing countries Disaster aftermath Increase the hardware contribution of the clients Make the system More robust More dynamic Able to function “off line”, in a mesh network 4/8
  5. 5. Example usage contextNo Internet, no central access point → Mesh 5/8
  6. 6. Target architecture Synchronization + authoritative source Features Fetch data associated to identifier Associate new data to an identifier Create/delete identifiers Search for identifiers based on contained data 6/8
  7. 7. (Planned) part of the solution Use Linked Data Provide identifiers Allows for connections among data sources Based on open standards Use a NoSQL back-end to store the dataassociated to the identifiers Optimized to store large amount of flat records 7/8
  8. 8. Linked DataGraph/facts based knowledge representation toolConnect resources to properties / other resourcesWeb-based: resources have a URI Try http://dbpedia.org/resource/Amsterdam 8/8
