rdfs:comment "The Cyber-investigation Analysis Standard Expression (CASE) ontology is a community-developed standard that defines concepts used in a broad range of cyber-investigation domains, including digital forensic science, incident response, counter-terrorism, criminal justice, forensic intelligence, and situational awareness. CASE includes all aspects of the digital forensic process, from evidence-gathering and chain of custody, to generating a final report. The goal is to increase sharing and interoperability of cyber-investigation information among organizations and between forensic analytic tools. CASE aligns with and extends the Unified Cyber Ontology (UCO). The preferred namespace abbreviation for this ontology is: case-master."@en ;
