(note : I touched on this idea a few years ago, nothing has really changed since then)
Idea : A data clearinghouse with public/open APIs. This would be the bridge between people like you and me and our ‘home’ data warehousing needs and the public at large.
Example 1: Billers, Banks, anyone who may send you a statement or bill : Instead of paper bills mailed to your home, they could use the standard API on the ‘outside’ of the clearinghouse to send you data about your bank account transactions, credit card bills, etc. On your side you can choose what to do with that data : feed it into your home version of quicken, file it away as a PDF in dropbox, do nothing, etc.
Example 2: Electronic Media you may buy (books, music, movies) can be delivered in a standard way through the clearinghouse to the storage back end of your choice : dropbox, your home NAS, itunes, etc. No more worrying about where your music is and what device can play it. All media players can support the standard API and they are in. Presto.
Example 3: Sharing data with friends and families : you choose the sharing rules, access, etc with your own API scheme and they do the same on their end but the public side of the clearinghouse uses a standard API to transfer the data and meta data.
The possibilities are endless and anyone could start this project and have it turn into something huge. If someone wants to start a company with me I’m in.
