Sensor, interface and data interoperability ESONET WP2 a) status

This document outlines the current status and future directions for sensor interface and data interoperability within the ESONET WP2 initiative. It highlights key interoperability initiatives, existing standards, and work items aimed at improving sensor systems’ integration and data management. Recommendations for the realization of future observatory systems are discussed, alongside an inventory of current standards and interoperability concepts. The aim is to provide a cohesive framework that fosters collaboration and data sharing across national and international platforms, ultimately advancing ocean observation capabilities.

  1. Sensor, interface and data interoperabilityESONET WP2 a) status Eric Delory dBscaleEnv. Tech., ICCM, ICEO Antoni Manuel, Joaquín del Rio SARTI, UPC-CSIC ChristophWaldmann, KDM

  2. Outline • Interoperability initiatives • ESONET statement and WP2 a) work items • Where we are: inventory of standards and interoperability initiatives • sketch of the application of standards to a generic sensor system • Where we are going: existing systems, to map necessities and drawing recommendations

  3. ESONET statement <<The ESONET federation will oversee standards, data management and co-ordinate observatory deployment. Data will be interfaced to national and international data centres.>>

  4. WP2 Standardization and interoperability a) workitems • Inventory of existing interoperability concepts as possible candidates for future observatory systems • Inventory of existing sensors and interfaces • Recommendations and roadmap for possible realisation schemes

  5. Inventory of standards and interoperabilityinitiatives • Identification and mapping of existing standards • Sensing systems • Communication • Data management • Identification of relevant interoperability initiatives (INSPIRE, GMES, IOOS, GEOSS)

  6. Interoperability initiatives • INSPIRE: InfrastructureforSpatialInformation in Europe • GMES: Global monitoringforEnvironment and Security • EuroGOOS, IOOS Data Management and Communications • IEEE Committee on Earth Observations • GEOSS Global Earth Observation System of Systems

  7. GEOSS SBAs and Systems

  8. Component and servicesRegistrationProcess Done N Component has interface? ESONET or Component Register Component Register Service Y N Uses registered standard? Solution Accepted? SIF recommends solution Work with SIF N Y Y Enter solution in registry Reference registered standard

  9. Interoperability of ESONET at largefrom sensor interfaces to data

  10. Interoperability & Standards What should be standardised ? Interoperability What can be standardised ? “What few things must be the same so that everything else can be different” Eliot Christian, lead of GEO task AR 06-03

  11. Inventory of standards • Sensingsystemsfunctionalgroups • Networks topologies • Power • Data Storage/Memory • Clock • Interface • System Engineering • Languages • Cables • Connectors • Signal Modulation • Other features

  12. Inventory of standards

Inventory of standards • Data managementtowardsinteroperability • Metadata (content) • Data Format • Catalog/RegistryService • Data Access • StreamingProtocols • Semantics • Portrayal and DisplayService • Data TransformationServices • Quality/Assurance, Quality Control • Schema • Modeling, Simulation, or Analytic Processing Service • Archival • Communications and Telecommunications • Data Acquisition • EngineeringProcess • Development Environments and Software Languages • TechnicalDocumentation

  21. Inventory of standards • Data management towards interoperability

  22. Inventory of standards • Data management towards interoperability

  23. Inventory of standards • Data management towards interoperability

  24. Inventory of standards • Data management towards interoperability

  25. Inventory of standards • Data management towards interoperability

  26. Practical example • Many standards were formulated by the industry to define some or all of the following sensor attributes: - Metadata - Calibration methods - Definition - Identification - Means of interaction
