Over ten years ago, I wrote a little ‘thing’ for marking and saving records on maps. That was fairly ‘new’ then. For small groups and specific projects, I believe this is still useful, so I’ve revived it and re-written it, using Mojolicious.
There are a number of new features to be added, federation, new languages in the templates and a more general set of parameters.
Meanwhile, the project is here: https://sourceforge.net/projects/datamap/ and the Debian package, tested on Ubuntu 20 AWS and Linux Mint is here: https://sourceforge.net/projects/datamap/files/
I realise that it’ll be less popular, but I’m giving up offering native Windows versions of my software.
