Query: Validation and Inference of Schema-Level Workflow Data-Dependency
  Annotations   An advantage of scientific workflow systems is their ability to collect
runtime provenance information as an execution trace. Traces include the
computation steps invoked as part of the workflow run along with the
corresponding data consumed and produced by each workflow step. The information
captured by a trace is used to infer "lineage" relationships among data items,
which can help answer provenance queries to find workflow inputs that were
involved in producing specific workflow outputs. Determining lineage
relationships, however, requires an understanding of the dependency patterns
that exist between each workflow step's inputs and outputs, and this
information is often under-specified or generally assumed by workflow systems.
For instance, most approaches assume all outputs depend on all inputs, which
can lead to lineage "false positives". In prior work, we defined annotations
for specifying detailed dependency relationships between inputs and outputs of
computation steps. These annotations are used to define corresponding rules for
inferring fine-grained data dependencies from a trace. In this paper, we extend
our previous work by considering the impact of dependency annotations on
workflow specifications. In particular, we provide a reasoning framework to
ensure the set of dependency annotations on a workflow specification is
consistent. The framework can also infer a complete set of annotations given a
partially annotated workflow. Finally, we describe an implementation of the
reasoning framework using answer-set programming.
