5. Convert LCSH headings to GeoNames

Set-up

To complete this step, you need:

• Access to the command line
• Python 3+ with:
  • Beautiful Soup 4
  • numpy
  • pandas
  • requests
  • rdflib
• Scripts:
  • addGeoNames.py
  • convertGeoNamesFromLCNAF.py

---

Run addGeoNames.py

Transformations in this script:

• Transforms those geographic headings in columns spatial_fast and spatial_lcnaf into hierarchical string headings based on GeoNames.
  • Maryland--Baltimore --> Baltimore, Maryland, United States
  • Baltimore (Md.) --> Baltimore, Maryland, United States
  • This is done by finding "sameAs" references to GeoNames within the FAST authority files.
