Invoke the bin/export script with the name of the group to be exported
as a parameter.  E.g. to export RDF for the ucdavis group:

$ ./bin/export -g ucdavis [--group=ucdavis]

...which should leave you with output like:

$ tree exported_rdf/
exported_rdf/
└── ucdavis_2019-08-05T23:11:54.601Z
    ├── 0c9895ff-9470-4c70-bee4-b791ee179b34
    └── complete.log

* The output will land in the configured exportBasePath (defaults to
  './exported_rdf'), in a subdirectory named for the exported group and
  the time at which the export was run.
* Each RDF resource will have its own file (named for the resource).
* complete.log will be written at the end of a successful run.


Alternatively, instead of a group, you can export from all groups by specifying
-a or --all instead of a group name, e.g.:

$ ./bin/export -a [--all]

...which should leave you with output similar to what's described above, but with a
directory for each group, all inside of one containing directory for the export, named
'sinopia_export_all_<date>', e.g.:

$ tree exported_rdf/
exported_rdf/
