SUMMARY:Enabling Discoverable Trusted Services for Highly Dynamic Decentra
 lized Workflows
DESCRIPTION:Workshop\n\nEnabling Discoverable Trusted Services for Highly 
 Dynamic Decentralized Workflows\n\nBarclay, Simpkin, Bent, La Porta, Milla
 r...\n\nFifth generation (5G) mobile networks will revolutionize edge-base
 d computing by providing fast and reliable network capabilities to remote 
 sensors, devices, and microservices. This heralds new opportunities for re
 searchers, allowing remote instrumentation and analytic capabilities to be
  as accessible as local resources. The increased availability of remote da
 ta and services presents new opportunities for collaboration, yet introduc
 es challenges for workflow orchestration, which will need to adapt to cons
 ider an increased choice of available services, including those from trust
 ed partners and the wider community. In this paper we outline a  workflow 
 approach that provides decentralized discovery and orchestration of verifi
 ably trustable services in support of multi-party operations. We base this
  work on the adoption of standardized data models and protocols emerging f
 rom hypermedia research, which has demonstrated success in using combinati
 ons of Linked Data, Web of Things (WoT) and semantic technologies to provi
 de mechanisms for autonomous goal-directed agents to discover, execute and
  reuse new heterogeneous resources and behaviors in large-scale, dynamic e
 nvironments. We adopt Verifiable Credentials (VCs) to securely share infor
 mation among peers based on prior service usage in a cryptographically sec
 ure and tamperproof way, providing a trust-based framework for ratifying s
 ervice qualities. Collating these new service description channels and int
 egrating with existing decentralized workflow research based on vector sym
 bolic architecture (VSA) provides an enhanced semantic search space for ef
 ficient and trusted service discovery that will be necessary for 5G edge-c
 omputing environments.\n\nTag: Scientific Computing, Workflows\n\nRegistra
