wfcommons/workflow-schema: v1.1

The WfCommons project, an open source community framework that provides a collection of structured methods and techniques, implemented as part of usable tools, for analyzing workflow traces and producing synthetic, yet realistic, workflow traces. The WfCommons project uses a common format for representing collected workflow traces and generated synthetic workflows traces. Workflow simulators and simulation frameworks that support this common format can then use both types of traces interchangeably. This common format uses a JSON specification, which captures all relevant trace information as listed above. This release also provides a Python-based JSON schema validator for verifying the syntax of JSON trace files, as well as their semantics, e.g., whether all files and task dependencies are consistent
