Disaster metadata management system based on pycsw and its application
The management and sharing of disaster information has become an important technical mechanism for international cooperation on disaster risk reduction and is an important guarantee for improving comprehensive disaster prevention, reduction, and relief capability. Based on open source pycsw software, this study maps disaster core metadata standard, Dublin core metadata standard, and ISO 19115 geographic information – metadata based on an independently-designed disaster metadata standard. The disaster metadata management system is designed and analysed to realize the functions of online adding, editing, viewing, deleting, and data downloading of disaster metadata.
Metadata system applications can enhance the reliability of early warning systems and provide key support for disaster information by publicizing and sharing dataset information. Establishing metadata standards can provide technical support for sharing disaster data, which is conducive to using this data effectively.
