Importer for arabesque crawl report .sqlite files, which contain
file/identifier matches based on URL/identifier seedlists.
Uses a SQL query to iterate through table looking for rows with:
- GROBID status 200
- known SHA-1 (base32 format)
- known timestamp
Looks up release (by identifier) and file (by SHA-1). If no release exists,
bail.
If no file exists, create one from metadata (using both direct and wayback
URLs), link to release, and insert.
If file exists, optionally update it:
- if no release match, match to the release
- if new URL not included, add it (and wayback)
Config options:
- default URL rel
- crawl id (for editgroup metadata)
- identifier type
TODO:
- a mode to insert bare files even if identifier not known?
