VISS Protocol Server
Notes on known OSS VISS Servers:
- WAII
- W3C reference implementation for the VISS standard.
- Hosted by W3C as part of the W3C and Covesa cooperation agreement
- 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 links)
- 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
- Project hosted at 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- It appears they are no longer maintained but they are mentioned here for completeness.
VSS Data Store / Embedded DBs
WAII VISS server currently supports the following DBs are data store backends:
Notes on DB candidates to be added:
- Apache IoTDB
- MongoDB Realm
