HAPPI - Heuristic Access to Positions of Photon Instruments

Happi is a database to hold generic information for devices along the LCLS photon beamline.

This is general purpose database for PCDS to organize information on any device along the beamline. The general structure of the Python API allows users to use Device Containers to enter structured information into the database, while still proivding the flexibility needed for abitrary metadata.

Before entering any information, please consult the Conventions page. While the client is intelligent enough to catch certain errors there are still standards within the group we need to uphold.
