Database and Calibration
Storage of Calibration Data in the Database● See: http://
www.wiki.km3net.de/index.php/Database/Product_Tests_and_Parameters
● distinction: ● "data streams“ vs. ● "data sets of unique values to be applied for a finite timespan (e.g.
structures/objects)“.● for calibration: mostly second needed● fits into the already defined „TEST/CALIBRATION/MONITORING“● needed information:
● parameters to store (name, SI unit, range, needed accuracy)● associated products (if any) ● validity span of parameters/update rate (e.g. measured once per year or
once per second)● what are the parameters necessary for (online calibration, offline
calibration, information storage) 2
● Product data+calibration tests description● Basic entity: the «parameter»
● Name● Type● Allowed values● Array/Scalar● Array dependency
● Basic entity: the «test/calibration/monitoring» (includes factory datasheets)
● Name● Description● PBS/Variant of eligible products● List of parameters
● Parameter list: links a test to the parameters

PRODUCT TESTING AND INFO
From: Valencia Coll. Meeting:
● Product data+calibration tests documentation● Testing operation
● What● Where● When● Who● How● OK/FAIL
● Parameter values● Linked to the «parameter list»● Linked to the «testing operation»● NOTICE: Always use International System units
(e.g., not mA but A) – can be defined

PRODUCT TESTING AND INFO
● Product data+calibration tests documentation● Internal test results
● ASCII format for manual upload● XML/JSON format for automatic upload, see: http://
www.wiki.km3net.de/index.php/Database/XML_Data_Service● Automatically generated from test definition● Upload by cURL / wget or other webclients● Used for DarkBox/GreenBox

PRODUCT TESTING AND INFO
● Product data+calibration tests retrieval● GUI interface representation
● Automatically generated from parameter definition● Plots
● Formerly automatically generated● Now switching to plot definition tables in the DB
● Plot definition retrieval OK● Javascript/SVG plots OK● Need some sample data to complete/develop HTML interface
● Programmatic representation● XML/JSON format identical to the one used for upload● Direct retrieval of test results for specific UPI
● Use by cURL/wget or other web clients: see http://www.wiki.km3net.de/index.php/Database/XML_Data_Service

PRODUCT TESTING AND INFO
What needs to be done● Timecalibration (Mieke’s tables) are in place
● Need to establish the writing/reading● Other calibration is also partly done - an example (use case) would
be needed for everything to be stored● Definition document is there (but that is not so helpful if you want to
implement something)● C&S group can help but not do the job
