EDM4HEP Live Notes
==================

This is a document for taking notes during EDM4HEP meetings.

Connected: Andre, Erica, Gerri, Graeme, Valentin, Frank, Tao, Jiaheng

## Introduction and General Points

## Discussion on Run/Event/Collection meta data implementation

* different metadata for runs, events and collections
    * How to store? Depends on IO
    * How to contain
* For FCCSW: just storing arbitrary numbers in root file
    * Implemented in FCCSW Gaudi Reader/Writer
    * Comment: not really EDM, not portable to other IOs apart from ROOT
* What are the necessary interfaces to metadata?

 

### Next meeting:
