Data Classification and Tags
last updated on: Dec 9, 2023
Data classification and tagging can be defined as a process in which data is organized into categories so that data may be grouped and accessed in the most efficient way possible.
Nasuni Access Anywhere enables users and automated processes to attach descriptive information to files and folders in the form of metadata tags and data classifications.
A Tag is a generic type of data classification which is the available default classification in Access Anywhere and the only classification available if no others are configured. Metadata tags applied to files within the Tag classification can be a word, a phrase, a date or any string of characters. All of these are examples of valid tag values:
- sensitive data
- UK only access
- Dec. 2, 2020
Rather than use the generic 'tag' classification, other data classifications can be created that are more appropriate to a business domain.
For example if the Company was a legal company a Classification may be created such as 'Trial of Tom v Jerry' in which metadata tags could be then applied to file or object data that is applicable to this trial.
There are four types of data classifications:
- Classification - A user defined entry that is used to group a collection of tagged data assets.
- Private Classification - Similar to a “Classification” but visible only to the org. admin.
- Date - Similar to a “Classification” but the tag's value can only be a date.
- Content Detection - Similar to a “Classification” but created automatically by the Content Discovery feature. A Content Detection classification is created for each Content Detection category in the organization's Content Discovery configuration.
Effects of Common File and Folder Operations
(as of version 2106.04)
Copies and Moves
When a file or folder is moved or copied uploaded to a working directory (as opposed to trash), the new file in the destination folder will have the source file’s tags and classifications.
When a version file is promoted to be the new head file the new head will have the previous head’s tags and classifications.
When the head of a version file is pushed down by a newer copy of the file, the pushed down version will retain its tags and classifications.
When a file or folder is moved to trash, either directly or as the result of another operation, it retains its tags and classifications.
When a file or folder is restored from trash and does not overwrite another file or folder of the same name in the same location, the newly restored file or folder will have the trash file or folder’s tags and classifications.
When a file or folder is restored from trash and overwrites another file or folder of the same name in the same location, the newly restored file or folder will have the overwritten file or folder’s tags and classifications.
