public interface GeneralMetaData
extends StandardMetaData

The metadata naming interface for general metadata. Some meta groups are standard regardless of implementation. To handle standard metadata, we defined interfaces that are implemented by protocol-specific metadata groups. The GeneralMetaData interface contract is that the implementor supports meta data we might find as common general metadata, such as:

• FILE_NAME
• FILE_GROUP_NAME
• SIZE
• CREATION_DATE
• MODIFICATION_DATE
• OWNER
• ACCESS_CONSTRAINT
• FILE_COMMENTS
• DIRECTORY_NAME

An implementation specific class, such as SRB general metadata support these fields, but also may support further other metadata fields, such as:

• Replication number
• File type
• Data classification name
• Data classification type
• Access constraint
• Comments
• Comments date
• Deleted flag
• Owner domain
• Owner email address
