What kind of free license for a library?
« on: April 04, 2008, 04:43:25 PM »
I have just released TrIDLib. It's a library that wrap the feature of my TrID tool, to add filetype recognition to an app in a quick & easy way.

N.B. The webpage is a work in progress, as the docs. But there are some code samples that should already provide the basic info to get some work done.

But back on the topic. I intend this release to be a free edition, and I was hoping that there's already a known license (I mean, like GPL, LGPL, BSD, etc.) that I could publish this under, without having to write some convoluted semi-legalesuqe text!

My requirements would be:
  • the DLL will have to be distribuited along a brief txt file (ex. TrIDLib.txt)
  • a notice of the use of TrIDLib & me as its author will have to appear on the about box, docs & website (where applicable) of the app/tool/plugin that will use it
  • Just personal, educational, research but not commercial, not business, not for profit use

The rational is that I would like to see it used and spread around (someone for example coded a Total Commander plugin using TrID), and then if someone would see an use in a "money-making" project he would get a "full" version.

Any suitable license come to mind?

Thanks,
Bye!

I don't know an existing license that would cover this but there should be one.. Please do share with us whatever you decide to use since I'd be interested in it as well.

Sure!
A friend for example mentioned one of the Creative Commons variations/derivatives:
Attribution-Noncommercial-Share Alike 2.5 Generic.
It surely come very near what I was thinking. But I'm a bit perplexed because I haven't typically seen software using CC licenses.

Iirc your notice requirement is incompatible with the GPL - but you're best off staying away from that junk anyway. Also, if you only plan on releasing a .dll and not source, GPL is entirely no-go.

There's probably an existing license that at least comes close, so you could hunt around, and add a few clauses of your own if need be :) here's a list of opensource licenses, perhaps one is close enough that you can copypasta it :)

Yes, that's for sue! I quoted it just to explain what I was searching for.

Will keep searching around.
BTW, speeching of searches, this thread is already indexed on Google. I know they are pretty fast with popular sites but... this fast?! Impressive!
