About outercurve.org
outercurve.org is published by outercurve.org Editors. The site covers open source licensing and the archived project history of the Outercurve Foundation, which operated from 2009 to 2017.
What we publish
We publish two kinds of material. The first is practical writing about open source licenses, including MIT, Apache-2.0, and BSD-3-Clause, plus explanations of contributor license agreements (CLAs) and how permissive and copyleft licenses differ when you ship a product. The second is reference material about projects and galleries the Outercurve Foundation hosted between 2010 and 2017, such as NuGet, then called NuPack, Orchard CMS, and the ASP.NET Open Source Gallery. In that material we describe what each project was, what license or governance model it used, and where its code or successor project lives today.
We write in American English for readers who scan. Practical guides use numbered steps and tables; historical articles use a timeline and a project table with links to the current or archived repository.
Who this site is for
This site is written for .NET and open source developers, project maintainers, technical managers, and people who need to trace a project or gallery that was mentioned in an old blog post or release note. If you are trying to understand a license choice, the guides describe the practical differences between permissive and copyleft licenses, but they are not legal advice.
How we research
We rely on primary sources where they exist: press releases, archived foundation pages, repository commit histories, and public announcements from projects. When a source gives a date, we keep the month and year. If we cannot find a current repository for a project, the table cell says "no current repository found" rather than guessing.
Attribution is part of the record. Links to the original repository, archived page, or announcement appear in the text so that you can check the source yourself.
Corrections
If you spot an error, write to us through the contact page linked below. We review the claim against the source material and, when a correction is needed, we update the page and note the change. Because some of the Outercurve Foundation's records only survive in archived copies, dated claims should be traceable.
Independence
outercurve.org is an independent editorial project, not affiliated with the Outercurve Foundation, which operated from 2009 to 2017, with organizations that use similar names, or with any organization that used the domain before this project.
