The past few years have seen a variety of big-picture changes in open culture, open data, and open source licenses, both inside and outside the movement. This talk will survey a variety of those changes, including:

  • in Open Culture: the drafting and release of Creative Commons, version 4.0
  • in Open Data: increasing importance and complexity, including ODBL, CC0 and CC 4.0
  • in Open Source: the rise of permissive and web services licenses, interaction of open source licenses with mobile app stores, and javascript licensing
Detailed proposal

The past few years have seen a variety of big-picture changes in open culture, open data, and open source licenses - what options are available, how they are used, and how they apply to the world around us. This talk will survey a variety of those changes, and explain how they are (or aren’t) relevant to the movement.

Open Culture

Creative Commons has released version 4.0 of the Creative Commons licenses. This means changes in a variety of areas, including:

  • translations/ports
  • attribution
  • database rights
  • readability

Creative Commons Zero, a “public domain” license, is also becoming more common. We’ll survey these changes and discuss how they apply to the movement.

Open Data

  • New Licenses: CC 4.0 makes CC a serious option for open data, and the folks at opendefinition.org have seen many more. Are they relevant to us? If so, how?
  • Interoperability: how do ODbL and CC0 (used by Open Street Maps and Wikidata, respectively) work together with CC-licensed content? Do those present problems for us?

Open Source

  • Trends in licensing: while Mediawiki has maintained GPL licensing, much of the rest of the world is trending towards permissive licensing or the AGPL. Why? And does it impact us?
  • App stores and open source: the use of GPL in apps distributed through app stores has been controversial. We'll survey why this is, and how it might matter to the Mediawiki mobile apps.
  • Javascript: Javascript is now a genuine application programming language, and that brings with it licensing challenges. We’ll review discussion on wikimedia-l and elsewhere to see what this should be.

The talk should be of interest to anyone who publishes their work under an open culture or open source license - which is to say, just about everyone at Wikimania.
