Go package for working with Library of Congress data in an SFO Museum context.

lookup
For example:
$> ./bin/lookup -lookup-uri lcsh:// Airplanes
sh85002782 Airplanes
$> ./bin/lookup -lookup-uri lcnaf:// "Lindbergh, Charles A. (Charles Augustus), 1902-1974"
n79100565 Lindbergh, Charles A. (Charles Augustus), 1902-1974
A note about "lookups"
Please have a look at the A note about "lookup" documentation in the go-sfomuseum-airfield package. The issues outlined there are the same here. The "tl;dr" is:
It's not great. It's just what we're doing today. The goal right now is to expect a certain amount of "rinse and repeat" in the short term while aiming to make each cycle shorter than the last.
A note about the data
The data files in this package, and in particular the data/lcnaf.csv.bz2 file, are very big. As of this writing the data are loaded in to an in-memory sync.Map instance which means that a) it takes a non-zero amount of time to load b) consumes a non-trivial amount of memory. As such the lcnaf lookup table, derived from data which has 11M rows, only stores label -> ID pointers. It is not possible, at this time, to lookup the label for a given lcnaf identifier.
Remember: This package is tailored to SFO Museum's specific needs, and it's specific trade-offs, at the time of writing. As mentioned above "It's not great. It's just what we're doing today."
