+Mediaconch policies to fullfill needs of SLUBArchiv preservation requirements
+=============================================================================
+
+based on:
+* system policy "Example MKV FFV1 digitization policy" by mediaconch
+* public policy "Video file is MKV + FFV1-Intra + PCM or FLAC with CRC32
+  everywhere" by Jérôme Martinez (MediaArea), CC-BY-SA-4.0+
+
+Mediaconch is an open source tool to validate and standardize audiovisual files
+for long-term preservation, see https://mediaarea.net/MediaConch/ for details

+<policy type="or" name="Video file is MKV + FFV1v3 + 16bitRGB with CRC32" license="CC-BY-SA-4.0+">
+  <description>SLUB related policy to test that the video file is suitable for archiving purposes.
+    - Container format is Matroska with error detection (CRC)
+    - Video format is FFV1 with error detection (CRC) and with Intra mode (each frame is independent)
+    - Audio format is PCM (unfortunately it can not contain error detection) or FLAC (it has CRC by design)
+    This policy is based on:
+    - Example MKV FFV1 digitization policy.xml
+    - Video file is MKV + FFV1-Intra + PCM or FLAC with CRC32 everywhere.xml
+    If there are some policy violations or suggestions, please send an email to langzeitarchiv@slub-dresden.de
