Open Sensor Search

Open Sensor Search (OSS) is a platform for discovery of in-situ sensor data. It spans across large scale networks based on heavyweight OGC Sensor Web standards and protocols (SensorObservationService, SensorML, ...) and grassroots platforms and the internet of things (IoT) with a modular and open architecture. Open Sensor Search is based on the SensorInstanceRegistry and can be seen as its next version.

Source Code


  • Make sensor data discovery easy for users
    • Not as complicated as CSW
    • Not as simple as Google (though almost)
    • Tailored to time series discovery
    • Tailored to sensor web websites and data models (SensorML)
  • Make sensor data discovery simple yet powerful for developers
  • Integrate well with existing 52°North sensor web software (towards a Sensor Web Suite)
  • Easy to extend harvesting mechanism based on Javascript

Why is it "open"?

  • open source software
  • open standards for the APIs
  • open standards for the data formats
  • open harvesting mechanism - everybody can write harvesting scripts for their own data



Version 1.0 - GSoC 2013

  • organisation
  • architecture
    • checked Guice
    • checked Java 7
    • unchecked test driven development (unit + integration tests)
  • harvesting
    • checked Javascript
    • checked using quartz for scheduling
  • database backend
    • checked Apache Lucene/Solr
  • interfaces
    • checked SIR 1.0
    • unchecked simple RESTful interface to sensors
    • checked OpenSearch
  • uesr interface
    • unchecked new start page
    • unchecked login and script management

Version x.x (and later, also ideas and long term goals)

  • interfaces
    • CSW (reading)
  • harvesting
    • integrate with scraperwiki?
    • write harvesters in Scala
  • OAuth 2.0 for user authentication
  • database backend
    • use hibernate or Spring Data?
