0005 ## Schema versioning
0006 ## This is required to be an integer, and defined as 100*major+minor.
0007 ## Patch level changes are required to be schema invariant.
0008 ##
0009 ## If there are schema version changes that can be evolved, see the podio documentation
0010 ## for an example: https://github.com/AIDASoft/podio/tree/master/tests/schema_evolution

0015 # should getters / setters be prefixed with get / set?

0021 ## Some guidance:
0022 ## - Ensure data products usable without library dependencies (favor PODness where
0023 ## possible).
0024 ## - Move towards EDM4hep compatibility (to allow a transition to mainly use EDM4hep).
0025 ## - migrate away from custom indices in favor of podio relations
0026 ## - Use float most of the time except for 4-vectors where ppm precision is important.
0027 ## - Data alignment:
0028 ## - data should be aligned with a 64-bit structure where possible.
0029 ## - when using 32 bit values, use them in pairs (or after all 64-bit variables are defined).
0030 ## - same goes for 16-bit values (keep them aligned with the largest following component)
0031 ## - Explicitly specify the integer length (use the typedefs from <cstdint>,
0032 ## such as int32_t etc)
