Dear Peter and Thierry, thank you for your answers. I indeed contacted transfermarkt.com and write this just to finish up this conversation.
Here is part of their answer: "thank you for getting in touch with us. Basically our data is copyrighted under German law by Transfermarkt, so there is no license whatsoever. Therefore, we�re also no friends of data scraping and tend to block bots more and more. Rather we support the scientific community by providing data sets for single purposes in a structured process." Seems like this is a polite way of saying: do not create an R package with this purpose. My first package is going to be something else. :( Thanks and have a great day, Daniel [http://wweb.ktk.pte.hu/info/email-alairas/Oktat%C3%B3k/Dr.%20KEHL%20D%C3%A1niel/magyar/image001.png] Dr. KEHL D�niel adjunktus [http://wweb.ktk.pte.hu/info/email-alairas/Oktat%C3%B3k/Dr.%20KEHL%20D%C3%A1niel/magyar/image002.png] P�CSI TUDOM�NYEGYETEM K�ZGAZDAS�GTUDOM�NYI KAR K�zgazdas�gtan �s �konometria Int�zet H-7622 P�cs, R�k�czi �t 80. | www.ktk.pte.hu<http://www.ktk.pte.hu/> +36 72 501 599/ 23144 | ke...@ktk.pte.hu<mailto:ke...@ktk.pte.hu> ________________________________ Felad�: Peter Meissner [retep.meiss...@gmail.com] K�ldve: 2018. janu�r 24. 18:59 C�mzett: Thierry Onkelinx M�solatot kap: Kehl D�niel; r-package-devel@r-project.org T�rgy: Re: [R-pkg-devel] new package? - Sports data from transfermarkt.com using rvest 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.

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. Best regards, ir.
