Hello RJ,
Thanks for the updates and clarifications. I listed Jamendo because it was
the first service I managed to work with. Today, I managed to use
SoundCould’s Rest API to search and download music making GET requests, so
this will be part of my proposal too.
Going through the code, I've seen that SoundSource doesn’t provide a way to
stream from an online service. That is why I asked if I’m allowed to
download the audio file (and also because I didn’t know what to do from a
legal point of view).
The way that I see my proposal is: the user will be able to make queries
regardless the cloud service he is using. After the information is
collected from the user, a request, specific to each service, will be made
(using its API), and after a response is received (XML or JSON) it is
parsed. After this, the relevant information (artist name, track name,
download url, etc.) will be delivered to the user. This information
delivered to the user should be the same for each service. In this way, a
new cloud service will only need to implement how to make a request with
its API using the information provided by the user, and how to parse the
response in order to give the user the response in the desired format.
I was thinking that it will be useful for the user to also have the
possibility to download music from his personal cloud storage (for example
Google Drive). This would imply an additional authentication module, but
besides this, the searching and retrieving information mechanism will be
the same as for a cloud service like SoundCloud. What do you think about
this?
I’m working at my proposal as we speak and I’ll let you know when a first
version will be available.
Thank you,
Irina
