Second provenance challenge design overview
This page describes the implementation of how to answer the queries of the second provenance challenge.
The goal of this project is to create an api capable of querying different kinds of databases containing provenance data. The main focus will be on provenance generated by scientific workflows.
primitives
The api will deal with the basic primitives describing workflow executions.
node types:
| dataitem |
| module |
| moduleInstance |
| moduleExecution |
| workflow |
| workflowExecution |
| inputPort |
| outputPort |
