A formal approach for customization of schema.org based on SHACL
This addresses the challenge for data publishers in selecting appropriate types and properties from Schema.org, though it appears incremental as it builds on existing vocabularies and SHACL.
The paper tackles the problem of customizing the generic Schema.org vocabulary for specific domains and tasks by proposing a formal domain specification process that generates domain-specific patterns using SHACL operators, demonstrated with use cases in tourism.
Schema.org is a widely adopted vocabulary for semantic annotation of content and data. However, its generic nature makes it complicated for data publishers to pick right types and properties for a specific domain and task. In this paper we propose a formal approach, a domain specification process that generates domain specific patterns by applying operators implemented in SHACL to the schema.org vocabulary. These patterns can support knowledge generation and assessment processes for specific domains and tasks. We demonstrated our approach with use cases in tourism domain.
