The Metadata Enterprise Resource Management Aid (MERMAid) is a tool to develop, validate, manage and publish metadata records via secure internet access. It allows users and data providers to establish unlimited metadata databases to organize their metadata records as they choose (i.e. by program, project, data type, personnel). Some of the key features in MERMAid include (1) user-defined roles and permissions at the metadata management and database levels; (2) change tracking; and (3) enhanced validation. Also, your existing FGDC compliant metadata (in XML format) can be ingested into and managed through MERMAid.
MERMAid was developed by the National Coastal Data Development Center (NCDDC).
