The Walking Metadata (hermes example)

The hermes Python package was released (v1) last week, and now I'm going to show how to read the values instead a given metadata file from a feature class.

import hermes
if __name__ == "__main__":
    fc = r"c:\data_and_maps\usa\census\blkgrp.sdc\blkgrp"
    paperwork = hermes.Paperwork(dataset=fc)
    data = paperwork.convert()
    for k,v in data.iteritems():
        print k, v

In this example, I access the dataset, in this case a feature class.  To convert the metadata to a dictionary, call the convert().  Then you can use the dictionary iterator object to walk the data.

This example is just going to show something like:

metadata {some dictionary value}

Enjoy!
