Resolve LICENSE issues

[rightparen]

Audere needs a LICENSE file checked into the repo that we can use to check the client filter code into our open source repo.

The license for the server (including binary model and code) at least needs to allow us to run the server and to modify the code for internal usage. We probably have enough documentation spelled out in Slack and emails that this may not need to be an explicit file.

The license for the model file used by the client filter at least needs to allow us to run and distribute the binary freely. We do need this checked in as a LICENSE file, preferably next to the model file so that we can include the LICENSE along side the file in our client binaries.

We probably need the license for the client code to be compatible with the MIT license. MIT and BSD are both good options here. We need this checked in as a LICENSE file, preferably in a directory above all the source code so that we can include the LICENSE in our repo and specify that IPRD holds copyright on all code underneath.

Assigning to @kumaakh for now, please feel free to redirect as appropriate.

In an email thread, @smakthal replied to my comments above, saying:

We agree with what you are outlining below and I think an AGPL license on just the tf-lite model file will still allow you to freely distribute it. If we put the model in a separate folder (Which I think it already is) and put its own LICENSE file in it will that suffice?

All server side code will be in a docker container and remain closed source. IPRD will issue a perpetual license for Audere to use and modify this code without any restrictions/obligations. As you say below, we might not even need a separate LICENSE file since it is documents in emails/Slack. All client side code (Phone App) will be released under the MIT license. The only exception to this will be the tf-lite model file which will be provided to Audere under AGPL.

This all sounds good to me. I think this implies the following changes in the repo:

1) Replace the contents of rdt-reader/LICENSE with text that specifies: (a) IPRD's ownership of copyright, (b) the grant of perpetual rights for Audere that you mention, and (c) a note that specifies that all files in the repo are governed by this license except where a closer LICENSE file overrides. 2) Put a copy of the MIT license that reserves copyright to IPRD in rdt-reader/RDTCamera/LICENSE. 3) Put a copy of AGPL license that reserves copyright to IPRD in rdt-reader/RDTCamera/app/src/main/assets.

Does that work?

@smakthal Please work with @kjhanna to resolve this. I can add stock license statements easily but I think @rightparen is indicating that we should refine them as described in the last comment

[smakthal]

@kumaakh I should have the perpetual license text by tomorrow.

@smakthal okay, sounds good.

For now, the main thing blocking me is that I need the MIT license on the Android code and AGPL on the client model. Once those two are in place I can land the client code in our repo.

The perpetual license for the server is helpful, but not urgent.
