Array Data 4 . Data

Example 1 This example shows two binary data blocks. The first one was compressed by the CBF CANONICAL compression algorithm and is presented as hexadecimal data. The first character ‘H’ on the data lines means hexadecimal. It could have been ‘O’ for octal or ‘D’ for decimal. The second character on the line shows the number of bytes in each word (in this case ‘4’), which then requires eight hexadecimal digits per word. The third character gives the order of octets within a word, in this case ‘¡’ for the ordering 4321 (i.e. ‘big-endian’). Alternatively, the character ‘¿’ could have been used for the ordering 1234 (i.e. ‘little-endian’). The block has a ‘message digest’ to check the integrity of the data. The second block is similar, but uses CBF PACKED compression and BASE64 encoding. Note that the size and the digest are different.
