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.

Goals

• 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
  • Simple OpenSearch-compatible interface
  • Powerful OWS Common-based KVP/POX interface (a.k.a. SIR 1.0, see SensorInstanceRegistry)
  • Provide a RESTful API to sensor descriptions with URLs als identifiers (http://opensensorsearch.net/sensors/ea214ou15 (.json, .html, .xml)
• 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

Features

• OpenSearch interface and simple search form
• Multiple output formats
  • HTML
  • KML
  • XML (SensorML)
  • JSON
  • RSS
  • Atom
• Standardized SIR interface (OGC discussion paper > SensorInstanceRegistry)
• SensorML to ebRIM conversion
• Harvesting of web services
  • SOS 1.0.0
  • SPS 1.0
  • IOOS Network based on a catalog file
  • ThingSpeak
  • Xively
• Maven build process and continuous integration
• responsive HTML user interface (see OpenSensorSearchResponsiveUI)

Roadmap

Version 1.0 - GSoC 2013

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