Already have that video on my hard drive! I think I’ve seen it twice and skimmed it once.
The first hypothetical situation I have then is pretty tangible I think, so I would like to start there if I may. There is much talk about sharing datamaps as a way to “transfer” data. This concept I understand fully. The data is on the network, so you just need to inform the third party of where the chunks are on the network. To do this, you give them a datamap.
If that datamap is not big enough to have to be split into chunks, do you just give them the hash of the datamap to retrieve, and then they can retrieve the datamap and the data on their own? That would make sense if that’s so. One caviat though, instead of a hash, isn’t the Structured Data type (I believe datamaps are SD) located through a field called an “Identifier” instead of a hash? Either way, the data is still able to be retrieved from the network only using 64 bytes of location information.
On the other hand though, if that datamap is big engough to have to be split into chunks, do you give them the data atlas so that they can reassemble the datamap that you’re trying to give to them?
I may be misunderstanding the data atlas - as I previously believed there to be only one per user, and it having all of your personal datamaps on there. In which case, sharing the data atlas would not be a secure way to allow a third party to access many files.
