WGs Getting started (~0-6 months after RDA endorsement)

The Persistent Identification of Instruments Working Group seeks to explore a community-driven solution for globally unique identification of active instruments in the sciences.


Instruments, such as sensors used in environmental science, DNA sequencers used in life sciences or laboratory engines used for medical domains, are widespread in most fields of applied sciences. The ability to link an active instrument (instance) with an instrument type and with the broader context in which the instrument operates (including generated data, other instruments and platforms, people and manufacturers, etc.) is critical, especially for automated processing of such contextual information and for the interpretation of generated data.


The identification and description of instrument models and instances is gaining momentum. Several disciplines are using established controlled vocabularies (standardised terms) to identify devices. Advances in Semantic Sensor Web technologies (encodings of sensor descriptions that are machine-readable and interoperable) have resulted in new instrument metadata schemas. Some Persistent Identifiers (PIDs), such as Universally Unique Identifiers (UUIDs) or Digital Object Identifiers (DOIs) are already being utilised.


Our group aims to build on these developments and establish a cross-discipline, operational solution for the unique and lasting identification of active devices.



  • Explore the use of a globally unique solution to persistently identify active devices
  • Recommend a metadata profile to describe active devices that harmonises existing identification standards and complements existing metadata schemas
  • Explore methodology/technology to register and resolve the new PID
  • Operationalise the solution, engaging instrument developers and manufacturers in the process


Relationship to other RDA interest and working groups

Current activities


The WG is currently collecting use cases for persistent identification of instruments, working on aligning the collected metadata, and drafting a first metadata schema.
