+abstract: |
+  The Rubin Observatory's Data Butler is designed to allow data file location
+  and file formats to be abstracted away from the people writing the science
+  pipeline algorithms. The Butler works in conjunction with the workflow graph
+  builder to allow pipelines to be constructed from the algorithmic tasks.
