upper_lower_case_letters_in_songHash
Firstly, I have to say that thank you so much for your great contribution to the boxrr-23 dataset, and also thank you for letting me know such an interesting dataset. All of this is full of challenges and freshness for me, a newcomer to the VR field. Here are some questions about the songHash id.
In the XROR file under each user's motion data (TAR folder), I have some confusions regarding the lower or upper case of songHash id.
The situation is if I follow the songHash id in any xror file of a user, such as "70BB751FE43AAD67463B6514E41DBD59BDE681D6", I download the corresponding map data according to the link "https://r2cdn.beatsaver.com/{songHash_id}.zip". But it doesn't work. After exploration, I found that after the uppercase letters in the songHash id are converted to lowercase letters (that is, "70bb751fe43aad67463b6514e41dbd59bde681d6"), I can find the map data of the corresponding song according to the above link.
I'm not sure whether the case problem of songHash id in the dataset may be due to a unified format problem processed by the dataset author when collecting data, or other factors, because it is actually just a case problem. However, it is easy to confuse people who are learning about the dataset for the first time (because people often directly look for the corresponding map data based on the hash id in the file, and if they can't find it, they will search the corresponding song name in the file from beatsaver, but they often can't find it, because there are many versions of the same song - the one you find may not match your current hash id. Therefore, users may only realize the fact that songHash id should be all lowercase letters by going to the beatsaver website to download existing songs and checking the composition pattern of the songHash id in the download link.
So, my main question is: (1) should the songHash id be converted to lowercase first before the corresponding map data can be found? Or (2) is there a better way to link to the corresponding song map data in the songHash design? In other words, is there another way to link to the map data that I don’t know yet?
Really looking forward to your reply. Thank you so much.
Hey Shujing,
thanks for pointing that out – I actually never tried to download the map data myself, so I never experienced this problem.
To your questions:
- sounds about right
- not that I know of
If I understand correctly, you had been able to solve your problem on your own already, but feel free to document your observation in the readme via Pull Request :-)
