OpenAtlas

This will be an ongoing task. Thank you Bernhard for providing an initial requirement.txt based on your system. I moved it to the install folder and made minor adaptions based on my (Debian/Linux) system.
@Andreas Olschnögger can you please take a look/test it too. Although it doesn't have to be immediately for this (7.2.0) version, we can just add a new issue in case you find/suggest something later.

Typically, the requirements.txt is located in the root directory. Applications will not be able to find/scan it in the /install directory. So an automatic installation of the packages will not be available. But I understand your desire to keep the root directory clean.

I changed one package and added one:

flask-babel from 0.12.0 to 1.0.0¶

The reason for that is this error message:
ImportError: cannot import name 'ImmutableDict' from 'werkzeug' (C:\Users\bkoschicek\Desktop\OpenAtlas\archive venv\test_venv\lib\site-packages\werkzeug\__init__.py)

I don't know why it works on your machine, but also a lot of people has this issue with werkzeug 1.0.1 and babel < 1.0.0. It is also possible to downgrade werkzeug to 0.16.1, but I think, using the right werkzeug version is more important than using the right babel version.

Added rdflib-jsonld¶

If we use the rdflib 5.0.0 instead of 6.0.1 we need another package: rdflib-jsonld==0.5.0. rdflib 6.0.1 included the rdflib-jsonld features and since we only have one graph serilization, I thought it would be safe for development enviroments to use 6.0.1. But since it works with both packages, let's keep it that way

File location
Good point, I moved it back to root.

Version changes
This also sounds fine, I expected this will be an ongoing issue and the more feedback for adaptions we get the better.

File encoding
When doing a git diff for the last commit, git wouldn't show telling it's a binary. Not sure what happened there but turned out encoding was set to UTF-16 so I changed it to UTF-8 and now it works as expected.

File structure
I sorted the list alphabetically which looks more readable

Thank you Bernhard for starting this process, looks like we getting somewhere :)
