External Nodestore

---

Detailed Description

An external application that manages its own data and data model.

To plug in outside data sources, one can use

• VariableNodes with a data source (functions that are called for read and write access)
• An external nodestore that is mapped to specific namespaces

If no external nodestore is defined for a nodeid, it is always looked up in the "local" nodestore of open62541. Namespace Zero is always in the local nodestore.
