We should talk to these folks at the Online Computer Library Center.
There has to be some possible convergence between the Dewey Decimal Classification and block chain technology which facilitates the advancement and diffusion of knowledge.

I'm not sure what it is - but they've been doing what we aim to do for a very very long time.

----------

    So in that spirit - here is my suggestion.


    A Killer Application is designed for the submission and review of erratum such that rather than going to the publisher to find corrections in a book you have just bought - you can feed the Datacoin Browser an ISBN number and it will render a few pages for you to print.

    Inputs would work like this: a reader finds an error and submits the correction to the Killer Application.
    The Killer Application manages consensus for the correction by crowd sourcing yay or nay votes and by allowing the author and publisher to bless a correction through the Killer Application.
    Both the correction and the ongoing vote tally are inscribed into the chain.
    The Killer Application uses its own schema and metadata to curate the collection so that the most valuable data rises to the top and we have full CRUD functionality.

    DTC is used to inscribe the data and to potentially compensate a contributor who will be given or provide a Datacoin address upon submission.

    In the future, a publisher would obtain a GUID for each edition, directly from the Killer Application.
    A reader could scan a QR code of the GUID which then takes them directly to the Killer Application's collection of errors and corrections for the edition.

    Possibly, we could even make the GUID compatible with public-key cryptography so that it is actually the public key to a new edition submission.
    This would enable the mechanics of having a publisher or author bless a correction.
