#UNESCO in partnership with #CODATA has launched a consultation to explore how the principles of #OpenScience could guide efficient policies for #datasharing in times of crisis such as pandemics.

Interested experts are invited to provide feedback on the UNESCO factsheet, guidance document and checklist for Open Science-driven data policies for times of crisis until December 16.

Continued thread

2/3 Continuing on Codata:

- Like operations on a Java interface: define how to get values out, caller chooses which operation to call
- You construct an object with computations (methods) to produce values on demand

Key distinction:

- You consume (destruct) data by pattern matching on a value
- You construct codata by providing computations to implement the destructors

1/3 Demystifying Codata (or coinduction):

In strict functional programming, we typically think about:
- Values (data): constructed upfront, directly visible, accessible
- Computations (functions): consume/destruct data, opaque

Codata flips this around:
- We define how to observe/destruct it
- Construction happens on-demand when observed (observed = selecting one of the methods in the object to call)

I have released fundamental_constants v1.3 with the just released 2022 #CODATA adjustment. Don’t expect great features, I will keep it simple (my only plan is to update it every four years). It just offers #Fortran modules with parameter values containing the 355 physical constants.
