## ISSN

From CSV file:

    # See "start off with" command above
    time ./fatcat_import.py import-issn /srv/fatcat/datasets/journal_extra_metadata.csv

Usually a couple minutes at most on fast production machine.

## ORCID

Usually tens of minutes on fast production machine.

    time parallel --bar --pipepart -j8 -a /srv/fatcat/datasets/public_profiles_1_2_json.all.json ./fatcat_import.py import-orcid -

## Crossref

Usually 24 hours or so on fast production machine.

    time xzcat /srv/fatcat/datasets/crossref-works.2018-01-21.json.xz | time parallel -j20 --round-robin --pipe ./fatcat_import.py import-crossref - /srv/fatcat/datasets/20180216.ISSN-to-ISSN-L.txt /srv/fatcat/datasets/release_ids.ia_munge_20180908.sqlite3

## Matched

Unknown speed!
