RE: [dsdp-mtj-dev] Release parts of MTJ in a permissive license
|
We haven't had much trouble using the UEIimporter of MTJ as it is for our SDK,
so we never really discussed doing changes to it to fit our needs, so for us,
the licensing hasn't been an issue.
The problems we have had with it were in combination with an internal version of our
SDK, but then we made the changes to the SDK instead to fit with MTJ, since our external
SDK version worked fine with MTJ.
I don't see any need for a change from Sony Ericsson's part,
Br Tomas

Subject: Re: [dsdp-mtj-dev] Release parts of MTJ in a permissive license
Please note: This is my personal opinion, and does not reflect the
opinion of my employer... ;)
I somewhat concur with both, Gorkem and Dan - Changing the licensing
to EDL would make it easier for companies to create "proprietary"
implementations without contributing back to Eclipse, and yes,
publishing sample code is a "easy way out" for writing documentation.
We need to think through the advantages and disadvantages of such a
license change, and I'm curious to hear more feedback from potential
"adopters".
I dont know if there are companies "out there" who would like to
implement a closed source SDK importer but have struggled to do so.
IF this is the case, and we as a project want them to use MTJ, we could
a) Improve our documentation and help them implement their closed source
importer
b) "give away" the UEI importer to be used by them as a template.
(which would require EDL, otherwise their importer would have to be EPL)
c) convince the company that they should create an open source (EPL)
version of their SDK importer.
I wonder how this would affect people contributing "back" to the UEI
importer?
I assume that even if people create their own EPL version of an SDK
importer, they would not contribute any improvements back into the UEI
importer code?
On the other hand - I understand that the EDL license for the UEI
importer would allow another company which has a "almost UEI" compliant
SDK to use a proprietary modified UEI importer w/o giving changes back.
This is probably mostly concerning, considering the UEI standard is not
actively maintained, and there is a potential for incompatible
extensions to the UEI standard by companies.
Again, this was really just a "testing the waters" proposal, and i would
like to hear feedback from the wider community, especially from
companies who are currently implementing their own SDK importers (RIM?
Ericsson? S/E?).
Given that this would be a difficult process to change the license, we
would need a very good reason for this.
