Perfect appreciate you citing it in the project as a whole!

MIT license is fine for your library it’s compatible to incorporate with Alv2.

Individual types aren’t likely to have Tika as a reference (some of the data already exists and I’m automating this process), but the project as a whole will include this information.

 

The one thing that I forgot to mention is that the data library is itself MIT licensed (I would choose Apache 2 these days, but this is a choice twenty one years old and I have had too many contributors to relicense

It).

Agree with Tim!

 

Thanks for using Tika, really appreciate it Austin. If it’s not too much trouble would love a link/citation back to Tika in your work.

 

Thanks,

Chris

I can't think of anything in our Apache Software License 2.0 that would cause problems, and you're not infringing on trademark, as far as I can tell.

 

Thank you for reaching out, let us know if you find any problems with our data, and enjoy!

 

Cheers,
