USAGE PARAMETERS

• --cutoff 2023-01-10
  • Grab changes from the specific date
• --list inputlist.txt
• --category "Name of category on Commons" Use either of these to specify which files to use. If using --list, the list must consist of a list of files, eg

Damskor - Nordiska museet - Nordiska kompaniet NK K3c 1 0130.tif

• -- config configfile.json This file defines which changes to grab. It must be structured like

{
"info_template": {"Nordiska museet Bildminnen image" : "description"},
"relevant_sdc": ["P180"]
}

The three things we specify are

1. which infotemplate to process,
2. inside the infotemplate, which field to process (contains descriptions to diff),
3. which SDC statements to diff (P180 is depicts).

• --out outputfile.json Optional, name of output file. If not used, a generic timestamped filename will be used.
