If the prov.dir option is used, the provenance directory is not normalized to use Unix-style paths. In Windows, for example, the provenance directory may appear as c:\prov instead of c:/prov in the JSON file. This could be addressed by adding winslash="/" in line 175 of API_core.R:
base.dir <- normalizePath(getOption("prov.dir"), winslash=”/”, mustWork=FALSE).
