What WissKI is

WissKI is a free virtual research environment and linked open data management system for scholarly data. It is designed especially for galleries, libraries, archives, and museums, with editorial workflows, custom user roles, multilingual content, media management, and custom content types. Ontology-based modeling is optimized for CIDOC CRM while allowing other standards. Pathbuilder provides a graphical way to define ontology-driven structures and translate between Drupal and SPARQL endpoints without writing queries or code. WissKI supports SQL imports, exports in various formats, REST API access, and communication through a SPARQL 1.1 endpoint. Content can use persistent identifiers and Drupal revision control. Integrations include DNB, GeoNames, and Drupal modules. Installation options cover Windows, macOS, and Linux, with WissKI Cloud available for evaluation; web, API, and self-hosted use are also listed. The free plan requires Drupal and a triple store. Current ontology support is limited to OWL 1 DL RDF/XML notation.
