Discovery Services
Standards make it possible...
• Every NEIEN v1.1 compliant node uses the same WSDL file.
– All Query and Solicit requests use the same calling structures.
– All Nodes respond to a subset of known requests.
• Each Request is unique and is defined in an FCD.
– All Parameters are defined by number, order, type and optionality.
– All Requests produce XML based on a message schema of a specific
dataflow.
• Each Dataflow is unique and is defined in a DET.
– All Data flows have a unique Namespace and contain one root file.
– All Data flows are built from component schema and have at least one
message schema.

Standards make it possible...
The Query Request
• securityToken – string
• request – string
• rowId – string
• maxRows – string
• parameters() – array of strings

How does it work?
The Manufacturing
Process uses
standardization to
build tools and
automate processes.
The Node Discovery
Process works the
same way.
Discovery Services
How does it work?
