embARC (“metadata embedded for archival content”) manages internal file metadata including embedding and validation. Created by FADGI (Federal Agencies Digital Guidelines Initiative), in conjunction with AVP and PortalMedia, embARC features flexible options for DPX (Digital Picture Exchange) files to support FADGI’s Guidelines for Embedded Metadata within DPX File Headers for Digitized Motion Picture Film as well as required SMPTE 268 metadata rules. embARC enables users to audit and correct internal metadata of both individual files or an entire DPX sequence while not impacting the image data. Functionality for additional file formats is in development, including MXF files. embARC is developed in JAVA.
