Legality of sharing Perry's Databases #71

Closed dejac001 closed 3 years ago

dejac001 commented 3 years ago

Is it legal to copy data tables from Perry's chemical engineering handbook and redistribute them under an MIT license?

I know the book costs about $100-$200 bucks.

Hi Robert,

I am not a lawyer. The coefficients in Perry's are public; and they are developed by AICHE's DIPPR, not Perry's publisher actually. As regressed coefficients are the result of a computer program and cannot be copyrighted, there is no issue.

For the record, I would be happy to work with the DIPPR should they see an issue with this distribution. The data in Perry's is a tiny portion of their very impressive work. They are an incredible team and have written many excellent papers that have helped both me and Thermo!

Sincerely, Caleb

In order to be a secondary distributor of DIPPR, you need a license: https://www.aiche.org/dippr/events-products/801-database/secondary-distributors

It looks like it costs at least $150 / year.

They say "To become a secondary distributor, please contact us at dippr@aiche.org."

Hi Robert, This is an open-source non-commercial project. I don't have a relationship with the DIPPR, nor did I obtain these coefficients from them directly; we have no contractual relationship. Sincerely, Caleb

I realize that. I'm just saying that you should be careful.

I'd like to use these data tables too, but I'm going to email DIPPR and see if it's allowed first.

@CalebBell, in the rare case you ever come by any issues with the use of data (like DIPPR) in your open-source projects, let me know and my lab group and institution will see how we can help.
