    Constant Field Values
  - BAGGING_DATE
```
public static final String BAGGING_DATE
```

    See Also:
    
    Constant Field Values
  - BAG_SIZE
```
public static final String BAG_SIZE
```
    The size or approximate size of the bag being transferred, followed by an abbreviation such as MB (megabytes), GB (gigabytes), or TB (terabytes): for example, 42600 MB, 42.6 GB, or .043 TB. Compared to Payload-Oxum (described next), Bag-Size is intended for human consumption. This metadata element SHOULD NOT be repeated.
    
    See Also:
    
    Constant Field Values
  - PAYLOAD_OXUM
```
public static final String PAYLOAD_OXUM
```
    The "octetstream sum" of the payload, which is intended for the purpose of quickly detecting incomplete bags before performing checksum validation. This is strictly an optimization, and implementations MUST perform the standard checksum validation process before proclaiming a bag to be valid. This element MUST NOT be present more than once and, if present, MUST be in the form "_OctetCount_._StreamCount_", where _OctetCount_ is the total number of octets (8-bit bytes) across all payload file content and _StreamCount_ is the total number of payload files. This metadata element MUST NOT be repeated.
    
    See Also:
    
    Constant Field Values
  - BAG_GROUP_IDENTIFIER
```
public static final String BAG_GROUP_IDENTIFIER
```
    A sender-supplied identifier for the set, if any, of bags to which it logically belongs. This identifier SHOULD be unique across the sender's content, and if it is recognizable as belonging to a globally unique scheme, the receiver SHOULD make an effort to honor the reference to it. This metadata element SHOULD NOT be repeated.
    
    See Also:
    
    Constant Field Values
  - BAG_COUNT
```
public static final String BAG_COUNT
```
    Two numbers separated by "of", in particular, "N of T", where T is the total number of bags in a group of bags and N is the ordinal number within the group. If T is not known, specify it as "?" (question mark): for example, 1 of 2, 4 of 4, 3 of ?, 89 of 145. This metadata element SHOULD NOT be repeated. If this metadata element is present, it is RECOMMENDED to also include the Bag-Group-Identifier element.

    Constant Field Values
  - INTERNAL_SENDER_IDENTIFIER
```
public static final String INTERNAL_SENDER_IDENTIFIER
```
    An alternate sender-specific identifier for the content and/or bag.
    
    See Also:
    
    Constant Field Values
  - INTERNAL_SENDER_DESCRIPTION
```
public static final String INTERNAL_SENDER_DESCRIPTION
```
    A sender-local explanation of the contents and provenance.
