About
Many organizational processes cross the boundaries of individual organizations. This is especially true for the academic sector where mobility programs like "Erasmus+" enable students to be enrolled with different universities throughout their studies. However, the technical means to enable the necessary collaboration between different institutions and their administrations are often not adequate. Many tools for group messaging, file exchange, or domain-specific applications do not work or lack functionality as soon as users or data from outside an organization are involved, such that E-Mail is a widely used fall-back. Based on terminology from the recent Interoperable Europe Act - (IEA) we will present technical and semantic interoperability solutions to address these issues. On the technical side, we present two existing protocols: OpenCloudMesh is an open file sharing protocol implemented by open-source solutions like Nextcloud and ownCloud. The Matrix protocol enables secure, decentralized group and instant messaging, but might also support further use cases like video conferences in the future. On the semantic side, we present a case study where we, based on existing vocabularies, model a university course catalog in the Resource Description Framework (RDF) serialization format JSON-LD. The RDF representation of the course data introduces a semantic context to the course data, making the exchange of the catalog data independent of specific APIs, thus enabling interoperability across heterogeneous data structures and university-specific systems. The introduced technical and semantic interoperability solutions enable public sector bodies like universities and enterprises to improve their cross-organizational collaboration without giving up their digital sovereignty to a centralized, commercial actor.
