Semi-Baked with some questions.

I have questions in parsing. So for now, I am parsing the text from the pdf in the background and saving it in the appropriate record in the db.

You have mentioned in the readme <<extract "project", "location" and "drawing">>, how should be the project and location be parsed. 
  Are they supposed to be got from the metadata?
  If they are supposed to be got from the text in the pdf, is there a specific format to which the pdf's should stick to?
