Achieving mobility of data and applications will be necesary for the next major thrust of the internet.
Roadblocks to mobility are sprouting everywhere as one after another the internet giants create APIs of their own.
How we meld these APIs going forward I won’t venture a guess at, but Simon Wardley has a post on the merits of open source and standards in this effort titled Competition, not greed, is good and it’s worth a read. You may see in the comments that he and I have a slight difference of view on this, I being an OS skeptic, but that doesn’t make his view any less informative.
