The documentation provided here describes how to use the Design Server.
Schema designer
Use the schema designer to define, modify, and view schemas. A schema describes the syntax, structure, and semantics of your data.
Testing part of a schema
You can test a schema by generating test data for an item or a group. The schema designer creates source and compiled maps that generate and validate the test data. The test-data-generation map automatically runs and produces a text file with the sample data. After that, the test-data-validation map automatically runs on the sample data file.
Invalid input message from test data generation
The message One or more inputs was invalid displays when test data generates successfully but the validation map flags some data as not valid. This message can occur when there are data type constraints, component rules, or restrictions that the sample data does not account for. Trace the validation map and inspect the generation map rules to find the data types that are not generating correctly.

- Flows
  A flow node invokes a sub flow within a flow. Sub-flows need not be wired to other nodes; it is valid to have a flow that is comprised of multiple sub-flows that each have listeners.

- Flows
  This documentation describes how Flows can be run from REST API, listeners, or they can be scheduled.
