MetaData assigned to Nodes The Requisition UI lets you edit the metadata defined in a requisition. The edit function in the Requisition UI is limited to only edit the context called requisition by intention. All other contexts are reserved for future use by other provisioning-adapters and similar applications like asset-data. While provisioning a requisition, the metadata from the requisition is transferred to the database and assigned to the nodes, interfaces and services accordingly. User-defined contexts If there is a requirement to add more contexts not managed by Meridian, the context name must be prefixed by X-. Any third-party software must take care to choose a context name which is unique enough to not conflict with other software.
