A Distributed Microservices Framework Integrating Taverna

Microservices can be described as "a granular set of small, independent, but highly interoperable services" [1] that are an essential part of a sustainable repository ecosystem. The University of Prince Edward Island has adopted a variety of approaches to microservices including scripted batch ingests, custom workflows embedded in content models, and PHP-based microservices [2]. In the last year, UPEI has built on their existing microservices framework by integrating Taverna, "an open source and domain-independent Workflow Management System" [3] and utilizing Taverna Workbench [4], Taverna's desktop tool, to create workflows. Within the repository context, there are several other projects that are using Fedora in combination with Taverna including the SCAPE (SCAlable Preservation Environments) Project whose work focuses on large scale ingestion, migration, and quality assurance to facilitate digital preservation [5]. This presentation will provide an overview of UPEI's microservices framework, their integration with Fedora, and the creation of repository services and workflows to address a variety of use cases.
