Yep, exactly. 

Susan Hoover, over on Slack LD4Libraries gave me a cool query doing just those things. I enhanced the query to include OPTIONAL variables, wrapped it in a Python script that takes a QNumber of a person as input, and outputs a JSON stream describing the person. See attached? Example usages:

  # Abraham Lincoln (attached)
  ./person2metadata.py Q91
  
  # Hector piped to jq for pretty display
  ./person2metadata.py Q159666 | jq
  
  # Charlemagne piped to jq and paged
  ./person2metadata.py Q3044 | jq | less -S
  
The next steps are to:

 1. expand the list of properties so the metadata
    of other things (like honor, beauty, or United
    States of America) can be garnered

 2. allow the script to take multiple inputs

 3. create a network graph file from the results

In the end, I will be able to study and visualize the characteristics and relationships of many named-entities in a given collection of narrative works.

Fun!
