Integrating our data in a decentralized Web ecosystem

Where is our butler?

The data our butler needs is
stuck in closed ecosystems

We can publish our data on
decentralized data spaces

I am part of the KNoWS lab

• Our lab works on
  knowledge on Web scale
• My research focus is on the
  publishing of personal data

• Integration of open data
  is an optimization problem
• Integration of personal data
  is a governance problem

We need to extend our data spaces
with governance functionality

• We require control of our data
• We require usability of our data
• We need to track usage of our data

We need control over our data

• Policies enforce rules and preferences

• Policies provide flexibility in data selection
• Policies enable static and dynamic conditions
• Agents can negotiate for exceptions
• Reasoning provides proof

We need our data to be usable

• Interfaces reconcile access and control

• Interfaces must reflect our policy requirements
• Interfaces provide only requested data
• Interfaces enable discovery of additional data
• Reasoning provides proof

We need to track usage of our data

• We store receipts of data exchanges

• Receipts give an overview of data exchanges
• Receipts allow us to detect misuse
• We create a feedback loop to our policies
• Receipts provide provenance
• Signatures provide trust

We can automate integration
of our personal data

control

• Policies help us trust
  agents in our data space

usability

• Interfaces help agents find
  relevant data in our data space

usage

• Receipts lets us track data usage
  and adapt our policies accordingly

There is our butler!
