| Description: The onboard_compression_class attribute identifies the type of on-board compression used for data storage and transmission. Note that the onboard_compression_type identifies the specific compression algorithm used (for example, ICER), whereas the onboard_compression_class gives a simple indicator of the type of compression mode. Valid values: 'Lossless', 'Lossy', 'Uncompressed'. |

| Permissible Value(s) | Value | Value Meaning |
| | Lossless | Lossless compression means that after compression and decompression, the data is the same (bit-for-bit) as the original. |
| | Lossy | Lossy compression means that the data after decompression differs in some way from the data before compression. |
| | Uncompressed | Uncompressed data is also lossless, but use of the "Uncompressed" value indicates that data was not compressed. |
