Today I stumbled upon wiki.camerabits.com for referencing metadata tagging. It was easy to find Wikimedia metadata Labels (which are like OSM Tags). Here is what I am thinking about mapping using exiftool, a command-line tool for displaying, adding and modifying media file metadata Labels:

• Source (same as Tag source)
• Description (same as Tag description)
• Web URL (same as Tag contact:url)
• Identifier (same as Tag wikidata)

Here are some other Labels that I’ve found to be useful:

• Persons Shown (semicolon separated list value)
• Persons Shown with Details (semicolon separated list of wikidata values)

Here are some static Labels that I would apply to all the public artwork for OSM:

• Copyright Info URL=https://creativecommons.org/publicdomain/zero/1.0
• Copyright=Public Domain
• Copyright Status=Public Domain
• Copyright Notice=Public Domain
• Rights Usage Terms=No Copyright

I would add custom Label=value pairs to the exiftool configuration file (which I am learning) for compiled media formats (i.e. PDF, PNG, JPEG, etc) originally from source (i.e. TeX, ODF, HTML, OpenXML, Markdown, Wikitext (and referencing wikidata instead of URLs/URIs)). These new metadata Labels would encode information about how to organise the source files, maybe even for fonts or images (if necessary):

• Src Format=tex (the file extension format for the source code)
• Src List=main (semicolon separated list of files in the src directory without extension)
• Src main=\documentclass{article} \usepackage[paperwidth=50cm, paperheight...

I am trying to come up with a most likely workflow for putting information boards onto OSM. A simple JPEG is not vector or basemap enough, and I don’t see SVG as a viable typesetter. A goal is to make the format editable by anyone, hence the TeX format in the PDF metadata (.tex file is not itself allowed to be uploaded to Commons, and neither are archive files). The documents I have already prepared will download and insert SVG files hosted on Wikimedia Commons into the document, so they would not need to be sneaked into the metadata. The only problem I foresee is media uploads being filtered by custom Metadata Labels. This is why we need to work together.

Sorry, if this post was not for you. I just want to map everything 1:1. Anyone have ideas how best to achieve this goal and/or where to go from here?
