Path Metadata Heuristics

Context

Use this when deriving title, author, year, and category from book paths before indexing into Solr.

Patterns

1. Honor explicit filename structure first

   • Author - Title (Year).pdf → author/title/year from the filename
   • Category/Author - Title (Year).pdf → category from folder, author/title/year from filename

2. Use folder depth to separate category vs author

   • Category/Author/Title.pdf → first folder is category, second folder is author
   • Author/Title.pdf → parent folder is author when the filename does not look like a series/journal issue

3. Handle real aithena library cases

   • amades/Auca ... amades.pdf → treat amades as author and strip the repeated author suffix from the title
