I like the term “open code” and suggested it be used recently in the openmod working paper to contrast with “open data”. But this was to replace the term “open-source” – which can rightfully be applied to data – and not the term “open modeling”.
When I started the two Wikipedia pages on “open energy system models” and “open energy system databases” I thought carefully about the terminology and came to the conclusion that “model” and “database” offered the best differentiation. Under this scheme, open modeling does not imply open data, while open data is a prerequisite for open modeling.
Regarding categories, Discourse claims to use categories rather than create a large hierarchy of forums and sub-forums. Would this not imply that categories should be used liberally. Or am I missing something?
