I'm not sure if it is required, but I would definitely recommend it  
even if your handles will only be used internally.  This at least  
makes sure that any namespaces you use don't conflict with any that  
are currently in the system, or any that may be added.  While  
conflicts may not be important now, you never know if the identifiers  
you are using may ever become public or used in a different handle- 
aware organization.

I'm not sure I understand the question, but you can store any  
metadata you like (or pointers to any metadata) in handle values.

Not in the handle system itself, but there are instances of "metadata  
registries" which harvest metadata and can perform queries on that  
data to return a list of handles.  For one possible example (that I'm  
not all that familiar with) see:  https://adlregistry.dtic.mil/2/

Thanks,
Sean
