O2A REGISTRY ​

Manage metadata for platforms, devices and sensors or product related information for permanent transparency.

REGISTRY aims to create an authoritative repository for managing platform, device and sensor-related information. It was first launched in August 2016 and it will be continuously improved.

REGISTRY supports:

  • Metadata versioning including minting of PIDs for individual versions along with citation. Example: https://registry.o2a-data.de/items/93/versions/66/2361.
  • Provenance metadata for repositories as good-scientific pratice. Example: https://doi.org/10.1594/PANGAEA.961717 links dataset in PANGAEA to sensor description, under event information https://registry.o2a-data.de/items/93/versions/66/2361
  • Management and discovery of standard sensor-specific information (e.g. manufacturer information, inventory number, history of actions, precision, photos, etc).
  • Management and discovery of data-specific information (calibration reports, physical characterization of individual sensors, etc).
  • Management of parameter properties that trigger the automatic quality flagging.
  • Autocompletion of station metadata (required under "Actions") for all large and medium-sized german research vessels (Polarstern, Sonne, Meteor, Alkor, Heincke, Merian and Poseidon) using PANGAEA expedition catalogue.
  • Bookkeeping of ownership / affiliation of devices.
  • Machine-friendly access to metadata. Example: OGC compliant output standards.
  • Sensor properties are used in machine-friendly monitoring of data streams in near real-time.
  • Re-use of information in portals and various national and international service infrastructures. Example: https://marine-data.de/?site=platforms.
  • Use on board of RV Polarstern including synchronization of DSHIP action log with sensor actions.
