Re: [science-iwg] OpenChrom - KNIME

[<Matt.Gerring@xxxxxxxxxxxxx>]

Hello,

Yes here is the thinking...

GDA is not an open source project that can be reused commercially nor does it have a binary that people could reuse. We do not currently have intentions to migrate the GDA code to EPL, certainly not in the short term as I have to think of my blood pressure... It is used at a few locations around the world for data acquisition at synchrotrons but each one builds their own product from the code. It is important to understand this, it is a collection of code not a distributed executable product. We accept each of the licenses of the dependencies when building GDA individually as an institution and use it only internally.

DAWN and January are source and binary distributions and they are useful in many different contexts therefore an EPL license was chosen such that companies and institutions may integrate that code with their products and freely reuse it. We often use DAWN and January code inside GDA (note point made in first paragraph about this:). They are an important part of the whole for scientists using the software.

Some code today released in DAWN or January may have been migrated from a GDA codebase. Diamond Light Source holds the copyright and are free to choose to do this as needed in order to keep DAWN and January permissively licensed. Confusion does occur if I license header is not changed in some files but this is rare because Eclipse Foundation help with it.

NOTE: Soon we will contribute the Scanning project which takes the new awesome scanning algorithm out of GDA and licenses it open source, EPL. I am hoping to check in the code today at some point: https://github.com/eclipse/scanning as the initial contribution is agreed.

So in summary we are breaking up various things from our three millions lines of code and releasing them open source where we can. Other things will not be open source because they are pretty specific. In terms of KNIME it could be an option to release parts separately or do something like Triquetrum has. I like the parts approach because it has actually made our code more modular and testable.

Sincerely,

Matt

While DAWNSci (and January) was never license under GPL, the code came from GDA which was (and still is according to website[1]) GPL. For example what is now January datasets were GPL 5 years ago [2]. On the way it spent a little time as Apache [3].

Perhaps you could talk about that part of the journey?
