Goal
The aim is to specifiy and create a generic software library for timeseries with measured data. The library must be able to store timeseries with associated metadata. The library should consist of two parts:
An interface for other components that would like to store or access timeseries data. The library must enforce certain restrictions on incoming data, such as a valid timestamp. For accessing the data an database-cursor like interface seems appropriate.
The library must be able to characterize the data based on an empirical cumulative distribution function (ecdf). This means that min/max, average, median etc. should be represented based on the full data, not only the data that has been reduced in resolution. NOTE: This is currently an open issue, to be solved using complex stream processing techniques.
The library must store metadata for a given sensor.
