These\nare typically only used internally, so they do not need to be as user-friendly\nas those for \"normal\" datasets.  For example, it is not unreasonable to just\nhave \"path\" (relative to the calibration repository) as a (string) data id.\nDifferent calibration datasets may have different data id *spaces* (names of\nid keys and possible values), or they may share a space.\n\nCreate a SQLite3 file named `calibRegistry.sqlite3` in the repository\ncontaining the calibration files.  This should contain a table for each\ncalibration data id space.  The columns in the table should be \"id integer\nprimary key autoincrement\", \"validStart text\", \"validEnd text\", and then all of\nthe data id keys for that space.  Write a Python script to populate this table\nwith the metadata from the calibration files and put it in `obs_{camera}/bin`.\n\nFor each calibration dataset, write a sub-Policy under the calibrations\nsub-Policy within the mapper Policy giving the table for its data id space in\nthe calibration registry, the reference table in the input (not calibration)\nrepository registry containing the `taiObs` column, and specifying that\nvalidity range checking should be enabled.  If additional data id keys such as\nfilter/band or camcol are necessary, put them in a \"refCols\" entry.\n\nExample::\n\n    calibrations: {\n        gain: {\n            [usual mapping entries]\n            tables: gain\n            reference: raw\n            refCols: \"run\" \"camcol\" \"band\"\n            validRange: true\n        }\n    }\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flsst%2Fobs_base","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flsst%2Fobs_base","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flsst%2Fobs_base/lists"}
