Dutch Ships and Sailors is a project that aims to provide an infrastructure for maritime historical datasets, linking correlating data through semantic web technology. It brings together datasets related to recruitment and shipping in the East-India trade (mainly 18th century) and in the shipping of the northern provinces of the Netherlands (mainly 19th century). For the northern provinces, the database contains data on the personnel recruited, the ships, and other variables (muster rolls of the northern provinces of the Netherlands). Dutch Ships and Sailors is a CLARIN IV-project, hosted by Huygens ING in collaboration with VU University Amsterdam, the International Institute of Social History and Scheepvaartmuseum Amsterdam. The data from this project are divided over 5 datasets. See the ‘Thematic collection: Dutch Ships and Sailors’ dataset for a full overview. This dataset contains the interoperability layer for the Dutch Ships and Sailors (DSS) Linked Data. These RDF(S) files represent the shared classes and properties to which the classes and properties of the four DSS datasets are mapped. Furthermore, it lists the provenance of all named graphs in the datasets using the Prov-O ontology.
