A few days ago I released my language learning site using Tatoeba sentences to teach 6 languages. It is the successor of listeningpractice.org that I abandoned many years ago. It can be found at:
I am currently trying to figure out the best way to collect errors reported by the users and forward them to Tatoeba. It's still pretty early in the development process, there is still a lot of room for improvement, so please let me know if you have any suggestions (especially regarding the potential synergies between Tatoeba and Linguno).
P.S. I have talked to Trang about the site, and there are still some minor changes to be made in the Terms & Conditions regarding Tatoeba sentences. It is going take a few more days.
I really like your site and think it is a great use of open content. Good luck with it. I will be using it myself and have signed up.
However, you are right about the terms and conditions. Copyright subsists in (most of) the sentences, and there is a licence applied to them, which requires attribution and the ability for the end user to reuse the content you are publishing.
Thus, the T&Cs do need to spell out the source for the material and the licence conditions. In my view this needs to be linked on a page whenever it is used, especially if the sources vary. The user needs to be able to find out who wrote it for you to comply with the "by" condition and to know how to reuse the content themselves to comply with the "sharealike" condition. If the user has to trawl several sites to work this out, then the licence isn't being complied with.
This is complied with very well on clozemaster.com where the user can, for each sentence, find their way back to Tatoeba. That's how I found Tatoeba; I suspect the same is true for at least some other more recent contributors.
I hope this is something you agree with and will do. Don't forget you are building on the works of thousands of volunteers, whose work you are asked to appreciate through the licence, and you will want to encourage others to continue to contribute so your own product can grow in the future.
Sorry if that comes off as off hand - I certainly don't mean to be as I really like what you have done – but I am a very committed producer of open content and do believe that it is important for people to respect and promote the open-ness of content through complying with the licences.
It didn't come off as offhand at all. :-) I agree with everything you have said and I added a link to the Tatoeba page on the solution page of the conjugation and listening exercises.
It's an amazing website! I've just registered in there.
When do you intend to implement more languages?
Thank you. :-) Setting up a new language is quite a lot of work, so I don't think I'll get to it for a few more months. Right now, the priority is adding more stuff for the existing languages.
Got it! :D
