License conflict? MIT & LGPL #307

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The swfobject v2.1 and v2.2beta source references several other works
(search for "based on"), including James Edwards' cross-browser onload.
Follow the link you give in the source
(http://brothercake.com/site/resources/scripts/onload/) and you will see
James' code is licensed as LGPL. Do you have agreement from James to
license as MIT?

There are no license conflicts with any of the attributed sources named in the
swfobject.js file (all swfobject 2+ versions).

We reference these sources for the following 2 reasons:
1. Give people credit for the great research they have done and the work have 
shared
with the community
2. Give SWFObject authors a reference to more in depth details to a particular 
solution

Let's discuss all "based on" attributions in depth for SWFObject 2.2 
(uncompressed src):

1. Line 45, IE/Win feature detection based on Andrea Giammarchi's solution ->
This is just a description of the technique, no license attached

2. Line 78, cross-browser onDomLoad, Internet Explorer workaround based on Diego
Perini's solution ->
- license only required when using download script, which we don't use
- we have written our own custom code which is loosely based on the techniques 
described
- Diego Perini was kind enough to help us with the development of the customized
version: http://code.google.com/p/swfobject/issues/detail?id=165

3. Line 149, cross-browser onload, based on James Edwards' solution
- license only required when using download script, which we don't use
- we have written our own custom code which is based on the techniques described
- James also published this exact technique without attached licensing in the 
book
The JavaScript Anthology (http://www.sitepoint.com/books/jsant1/, p.15/16, a 
book
that James co-authored and I had the pleasure to tech-edited)

4. Line 540, cross-browser dynamic CSS creation, based on Bobby van der Sluis
- license only required when using download script, which we don't use
- we have written our own custom code which is based on the techniques described
- hey, the author is me

So there are really no licensing conflicts.
