The document discusses the development of a provenance management system (Sensor PMS) for linked sensor data, focusing on the importance of sensor provenance for effective data discovery and management. It outlines the integration of a domain-specific ontology to enhance the sharing and integration of provenance information and describes a future plan to implement provenance query operators. The presentation was part of the 48th ACM Southeast Conference held in Oxford, Mississippi, in April 2010.
