Manage the metadata of various storage types

Metadata management varies for different types of storage.

For file systems, extended attributes are commonly used, while for S3 compatible storage, metadata management is included in the protocol. The same applies to tape storage, where LTFS specifies how metadata should be handled.

Nodeum keep the traditional "attributes" : 


modeMetaKey = "Mode" 
uidMetaKey = "Uid"
gidMetaKey = "Gid"
mtimeMetaKey = "Mtime"
ctimeMetaKey = "Ctime"
atimeMetaKey = "Atime"

S3, metadata are set as x-amz-meta-key:

Additional metadata

Conservation of additionnal metadata

To organize and bring more structure to unstructured data, user needs to add specific business attributes.

These additional metadata created by the users are kept during each data movement. The preservation is full and secure. 

Example :

A file mytestext which has an extended attribute defined:

root@srv1:~# getfattr mytestext -d
# file: mytestext
user.ship="boat 1"

Nodeum moves the file into a S3 compatible Object Storage, the following metadata will be defined:  x-amz-meta-custom-ship=”boat 1”.  Additional Metadata are always following the files.
