Analysis Production Data
Programmatic interface to the LHCb experiment Analysis Productions database, which allows retrieving information about the samples produced. It queries a REST endpoint provided by the web application, and caches the data locally.
Usage
The apd
Python package is available in the lb-conda default
environment.
From Python
The Python module allows interacting from analysis scripts, doing e.g.
In [8]: import apd
In [9]: datasets = apd.get_analysis_data("SL", "RDs")
In [10]: datasets(datatype="2012", polarity="magdown")
Out[10]:

The apd-cache command allows caching the Analysis metadata to a specific location.
Design
Analysis Production information endpoint
This module allows downloading and using Analysis Productions information from the endpoint https://lbap.app.cern.ch/
Details about the endpoint can be found at https://lbap.app.cern.ch/docs#/stable.
