Interdisciplinary collection-based research is impeded by the fact that object data in collections are created with different domain-specific perspectives. This heterogeneity prevents the linking of object data, even if they have subject-related references to each other, and affects the following phases in the research data lifecycle: describe, discover, integrate. This TRAIL focuses on one aspect of this problem: interoperability of prove-nance descriptions of objects from archaeological and

Based on domain-specific data models, the subject of this TRAIL is the development of a con-ceptual data model realizing semantic interoperability for collection object provenance data for the different disciplines, its formal description using the Web Ontology Lan-guage (OWL) and its reference implementation in WissKI.
