• WAII
  • W3C reference implementation for the VISS standard.

  • Has support for historical (persistent) data
  • Has backend abstraction for VSS data stores
  • Architecture supports connecting southbound data feeders to a data store
• Kuksa.val
  • Project hosted in Eclipse.
  • Historically inconsistent support for VISS (Todo: add linkssee AMM presentation and mentioned PR discussion)
  • Architecturally live 'last value' data only. No current support for historical or persistent data.
    • Assumption is that persistence is left to northbound clients?
• Aos Edge
  • The Aos Edge orchestration platform provides a VISS Server as part of the Aos Edge Core embedded part of the platform to provide secure, abstracted data to services orchestrated by the system. Implementation hosted at the Aos Edge Core product site.
  • VISS support equates more to VISS v1, with access control provided by the Service definition controls in Aos Edge, rather than using the access control specified in VISS v2.
• Other earlier implementations
  • During the early development of VISS (e.g. v1) various groups created implementations.
  • It appears they are no longer maintained but they are mentioned here for completeness.
