Dynamic Workflow Composition with OSLO-steps: Data Re-use and Simplification of Automated Administration

e-Government applications have hard-coded and non-personalized user journeys with high maintenance costs to keep up with, e.g., changing legislation. Automatic administrative workflows are needed. We present the OSLO-steps vocabulary and the workflow composer: combined, they are a means to create cross-organizational interoperable user journeys, adapted to the user's needs. We identify the requirements for automating administrative workflows and present an architecture and its implemented components. By using Linked Data principles to decentrally describe independent steps using states as pre- and postconditions, and composing workflows on-the-fly whilst matching a user's state to those preconditions, we automatically generate next steps to reach the user's goal. The validated solution shows its feasibility, and the upcoming interest around interoperable personal data pods (e.g., via Solid) can further increase its potential.
