Table 25 describes the details of the Core 2017 Server Facet. This Facet defines the core functionality required for any UA Server implementation. The core functionality includes the ability to discover endpoints, establish secure communication channels, create Sessions, browse the AddressSpace and read and/or write to Attributes of Nodes. The key requirements are: support for a single Session, support for the Server and Server Capabilities Object, all mandatory Attributes for Nodes in the AddressSpace, and authentication with UserName and Password. For broad applicability, it is recommended that Servers support multiple transport and security Profiles. This Facet supersedes the “Core Server Facet”.
