embARC (Metadata Embedded for Archival Content)
Audio-Visual Working Group

embARC (metadata embedded for archival content) is a free, open source application that enables users to manage (i.e., audit, validate and correct) embedded metadata in Digital Picture Exchange (DPX) files as individual files or an entire DPX sequence as well as RDD 48 compliant Material Exchange Format (MXF) files including FFV1 in MXF , while not impacting the image data. Functionality for other formats will be added over time.

First released in 2019, embARC is in active development to support two major FADGI guideline projects:

• Guidelines for Embedded Metadata within DPX File Headers for Digitized Motion Picture Film (as well as required SMPTE 268 metadata rules)
• SMPTE RDD 48: MXF Archive and Preservation Format
  • Including RDD 48 Amendment 1: Mapping FFV1 to MXF

In addition, starting in 2024, embARC supports FADGI's research work with Software Accessibility for Open Source Digital Preservation Applications. Details about accessibility features are in the user guides.

Comments about all aspects of embARC are very welcome. Please submit comments to Kate Murray ([email protected]).

embARC is developed by AVP (Rebecca Chandler), Medex Forensics (Bertram Lyons and Dan Fischer), and PortalMedia (Caroline Shea and Clement English) with product testing by Metaglue (Oliver Morgan) on behalf of FADGI.

embARC carries a CC0 1.0 Universal public domain dedication.
