# System metadata

The system metadata are file attributes which cannot be edited (except for the name). The following system metadata are available on CAVATICA:

* **ID** - unique on the Platform (i.e. there are no two files on the Platform with the same ID).
* Status, where possible statuses are:
  * AVAILABLE
  * ARCHIVED
  * ARCHIVING
  * RESTORING
  * UPLOADING
* **Path** - indicates where the file is located, under which project or folder.
* **Name** - unique on the current path (i.e. it's not possible to have two files with the same name on the same path).
* Size.
* **Type** - can be file or folder.
* **Extension** - assigned automatically by the Platform (e.g. Extension = BAM).
* **Checksum** (please note that this information is currently available only for small number of specific files on the Platform).
* **Location** - indicates where the file is physically hosted.
* Creation Date.
* **Modification Date** (note: since file content is immutable, this can be only file metadata modification date).
* **Task ID**, which is available for task output files.
