I'm planning a language app for mobile devices using data from Wiktionary. I'm planning on web-scraping the content and compiling it into a database that I'll package with my app.
Most Wiktionary content is dual-licensed under the CC-BY-SA and GFDL. They provide useful information as to what that entails for developers. But it's still not quite clear to me what parts of my app need to be made available under the same licenses.
I think my database would be considered the "derived work". Does that mean I only need to make the database available under the same licenses or the entire app?
