I try to put a license file and appropriate statements in the documentation and code for all of my PLaneT packages. [Remember that the license for the code may be different that that for the documentation.] I've almost certainly missed doing that sometimes. So, I think it would be good to make it easy (or a firm requirement) to supply the license(s) in the meta-data. <div class="gmail_quote">On Tue, Oct 25, 2011 at 7:37 PM, Matt Jadud <<a href="mailto:jadudm@gmail.com">jadudm@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Hi all, I thought it was neat to see someone submit a Firmata library to the Planet. <a href="http://planet.racket-lang.org/display.ss?package=firmata.plt&owner=xtofs" target="_blank">http://planet.racket-lang.org/display.ss?package=firmata.plt&owner=xtofs</a> That said, it contains nothing whatsoever about a license. I can't remember: does the package metadata have an explicit license field? Should it be a required field? I poked a few libraries in the list; Untyped seems to be reasonably fastidious about including a LICENSE file, but this doesn't show up in the metadata. The handful of other libraries I looked at contained nothing in the docs or the code w.r.t. either copyright or license. Does this matter? When a GPL'd piece of Racket code does a planet require and pulls in code of unknown provenance... is it pulling in a binary? Source? Is that code still GPL'd, or is it now in violation (or some other confusing state of being)? Just to spot check what other communities do, I looked at CPAN. (No doubt mentioning CPAN in the same message as PLaneT could start a flame war, but that's not my intent...) <a href="http://www.perlfoundation.org/cpan_licensing_guidelines" target="_blank">http://www.perlfoundation.org/cpan_licensing_guidelines</a> They require a clear license. I don't really do enough hacking/contributing in the PLT space at the moment for this to be much more than a "troll" in some ways, but it certainly isn't meant that way. It's just that I was glad to see a connectivity layer for working with the Arduino appear, and then realized that the code wasn't licensed in any way... raising questions about how I could use it in my own programming.
