Dear List members,

maybe this is not the right place to ask, if that is the case, please forward me to the right place.
I developed some functions to download and transform football/soccer related data from transfermarkt.com.
There are plans to create my first package based on these functions and of course develop them and add more later. As far as I know there is no API to that page, so I am using the rvest package.
My question is: is this an OK thing to do? Should I contact transfermarkt.com? My german is not perfect (just like my english), this is what I've found on thier webpage. Does that mean one can not create a package related to that page? Or can't crawl at all? Or just not allowed to sell the data? If it is allowed, can one post the package on CRAN at the end?

Please if any of you have experience in that or just show me where to ask, do not hesitate!

Dear Daniel,

First of all you need to make sure that the licence of
transfermarkt.com allows the usage that you have intended. If that is
not clear from their website, then you should contact them rather than
us.

CRAN has several packages to assists in downloading data from online
sources. But the source has to allow that kind of usage.

Hey,

I am not a laywer but their terms are quite explicitly prohibiting
redistribution of their data without written consent.

Now you might build a package that does not collect, store and
redistributes the data but only allows to access the data provided there
'live' via some convenience functions. But I don't really know if that
argument actually is valid in any legal sense.

To be on the safe side, you probably should contact them.

Best, Peter
