Issue DM-1255: Metadata Store - experimental prototype v1
This first prototype will involve capturing metadata from a small set of image files. * Create a new schema file in the cat package (lsstSchema4mysqlW15.sql) with definition of tables that will be used to capture image metadata (see Exposure tables in other schema files), and some basic structure for capturing information about the entire repository. Decide which keywords are standard, and which should go to flat key-value area * Pick a directory (or several) with images, candidates: /lsst7/dr7/runs, /lsst7/releaseW13EP, /lsst3/DC3/data/obs/ImSim/pt1_2, /lsst/DC3/data/pt1.2.3k/datarel/ImSim * create test database, load schema * extract metadata for all images in a given directory and load metadata from fits headers.
