Add labels to graphs generated by `plotRuns()`
gothub opened this issue · comments
The DiagrammeR
package is used to make lineage trace graphs, and I haven't found a way
to make a legend, so instead the arrows connecting executions and files should be annotated.
The default would use the inverse relations of ProvONE, which are prov:wasUsedBy
and
prov:generated
, in which case the arrows point in the direction of data flow, i.e. from
older objects to newer, which I believe will be more easily understood to users of this package.
The user would be able to override this default and specify that the regular ProvONE labels are
used, such as prov:used
and prov:wasGeneratedBy
, in which case the arrows would point
backward
, from descendants to antecedents.
