There is a way to add proper custom constants to the Omnis environment. One could write an external component that reads a text file during component registration and builds a c++ table of constants. To add constants would simply then be a matter of editing the text file, although a restart of Omnis would be required. In this way the constants would be available from the Omnis catalog and would also translate well to JS Client.
Perhaps this could be a mini project, combined with a session, at EurOmnis 2017. What do you think Mike?
