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 | a dataitem that is input/output to a module execution |
| module | the module/service that is to be executed |
| moduleInstance | the module as represented in a workflow |
| moduleExecution | the execution of a module |
| workflow | a description of a process containing modules and connections |
| workflowExecution | the representation of a workflow execution |
| inputPort | represents a specific port thas can be assigned an input to a module execution |
| outputPort | represents a specific port thas can contain a product of a module execution |
Relations
| Relation | Input | Output | |
| exists | all | boolean | |
| equals | all | boolean | |
| annotations | all | dict of key/value pairs | |
