A Workflow-Centred Approach to Managing Semantic Artifacts As Linked Open Data

Semantic Artifacts such as vocabularies and lexica are increasingly published as Linked Open Data, yet their management often relies on fragmented and ad-hoc practices. This paper presents a workflow-centred approach for the ingestion, validation, editing and publication of RDF-based Semantic Artifacts within a dedicated infrastructural pilot developed in the context of the H2IOSC project and integrated with the CLARIN-IT infrastructure. The proposed workflow integrates certified repositories, automated quality checks, controlled editing environments and semantic web publication services, supporting both SKOS vocabularies and OntoLex-Lemon lexica. By formalising each step of the lifecycle of a Semantic Artifact, the workflow ensures compliance with FAIR and Linked Data principles, supports versioning and traceability, and reduces technical barriers for Digital Humanities practitioners.The paper discusses how a workflow-oriented design, as implemented in the LLOD pilot, can improve sustainability, reusability and interoperability of semantic resources across research communities.
