Re: [wakaama-dev] License clarification

["Sami Nurmenniemi (Haltian)" <sami.nurmenniemi@xxxxxxxxxxx>]

Hi Wayne, Julien and Mike,

Thank you all for the explanation. It was a bit confusing for me since I didn't find any mention in the Wakaama sources or eclipse.org that it's possible to choose either of those when both EPL-2.0 and EDL-1.0 are present.

Best Regards,

Sami

(I'm responding on behalf of license@xxxxxxxxxxxxxxxxxxxxxx which does not have the ability to post to mailing lists).

I am not a lawyer and nothing stated here should be regarded as legal advice.

As Julien describes, you can choose which of the two licenses that you want to consume Eclipse Wakaama content. That is, our intention is that you can choose to consume the project content under the terms of either the EPL-2.0 OR the EDL-1.0.

The pointer into the FAQ that Julien provided is more concerned with secondary licensing which is a different (albeit related) topic.

The FAQ entry that you're looking for is here:

4.17. If I take a Program licensed under the EPL, compile it without modification, and commercially license the result, do I need to include the source code with the object code distribution?

No. But you do need to include a statement indicating where the source code is available and information on how to obtain it. The source code may be provided by you, or you may choose to provide a reference to where the source code originated from, such as the correct repository hosted at git.eclipse.org.

HTH,

Wayne

Hi,

There is a couple of answer in the FAQ related to EPL/EDL dual licensing and how it works regarding copyleft:
https://www.eclipse.org/legal/epl-2.0/faq.php#epl-secondary

I'm not a lawyer, but from my software engineer PoV, it's either you pick the EPL with the patent clause and the copyleft clause or the EDL, which is a BSD-like license: no patent protection but no copyleft clause.

HTH,

Hello,

I'd like to have some clarification on the license of Wakaama.

The "NOTICE.md" says Wakaanda is licensed with two separate licences:

"This program and the accompanying materials are made available under the terms of the Eclipse Public License Version 2.0 ("EPL") and the Eclipse Distribution License Version 1.0 ("EDL"). "

Basically EPL-2.0 says that it's not possible to distribute the software as binary without also providing the source code. On the other hand, EDL says "Redistribution and use in source and binary forms, with or without
modification, are permitted provided that..."

So shortly:

• I we do include Wakaanda files in our embedded application, do we have to disclose the whole application source code?
  

Thank you,
Sami
