Business models that focus on data harvesting and persuation architectures causes

  • stagnating innovation
  • alienation amongst citizens
  • a few winners takes all
  • general exploitative environment

We need a new social contract

The Solid ecosystem
brings back choice
by decoupling data and applications
enables personal data control.

The Web strives to be universal, and thereby enables permissionless innovation.

  • Anyone can use the Web, regardless of
    • hardware

      desktop phone tablet watch

    • software

      operating system browser app

  • You don’t depend on these to innovate.
    • Build for the Web!
    • Standards provide interoperability.

Solid gives

  • Everyone a Pod, where you can store and manage your data
  • Everyone an identity, a WebID
  • An authorization system with fine grained control
  • Takes advantage of various security mechanisms

Linked Data


  • It is an address to something
  • You get a document back if you go there
  • It is also an identifier for that document


  • Generalized to identify something physical
  • You will get a description about me if you go there.
  • Can identify anything, including abstract things, like the type of weather.

People choose where they store every single piece of data they produce.

They can grant applications and people access to very specific parts of their data.

Separating app and storage competition drives permissionless innovation.

Permissionless innovation

  • Enables people to experiment with solution to their problems.
  • Counteracts technological elitsm.
  • Has historically brought unprecedented creativity to the world.
  • But isn't the whole solution

Personal Data Control

When people control their own data, they are

  • more resistant to persuation architectures
  • less dependent on data harvesting business models
  • more resistant to forms of exploitation
  • they are free to choose applications that suit them
    • use applications that matches their values
    • enables competition based on value added
    • since people are not locked in, anyone can enter with their innovations

Personal Data Control unlocks Permissionless Innovation

Personal Data Control Enables Smart Cities

  • Smart cities will require personal data.
  • Smart cities will need to respect their users
  • or create an unprecedented surveillance society

Shared mobility is important

It will:

  • Cut traffic
  • Cut emissions


  • City development must be democratically driven
  • People must have personal data control
  • We must not have a winner-takes all situation
