Re: [h5md-user] Species Data Type

[Olaf Lenz]

Hi!

Enum types indeed seem to be an excellent idea in the case of species. I wonder 
whether they would not be useful in some other cases as well.
The boundary springs into mind. We could specify that 0 always means "no 
boundary", 1 means "periodic", and when any other value is used, a 
corresponding Enum datatype has to be defined. 
This would avoid the strings-with-variable-lengths problem and still give the 
flexibility to define new values without clash with future versions.
