The renewed IDA has two storage areas for each project

Instead of one storage area per project, the project space in the new IDA will have two distinct areas: a staging area (read/write) and a frozen area (read-only). Both areas share the same project quota, so there is no need to manage or reserve space for each use separately.

In both areas project members can

  • view directories, files and file sizes
  • download files and directories to their own computer
  • share files and directories outside the service via a temporary share link
  • delete files and directories

Staging area is intended for collecting and organizing research data in preparation for storing them in the frozen area. In the staging area

  • project members can add, rearrange, rename, overwrite and delete data
  • directory and file metadata are not saved in metadata repository nor visible for users in the coming tool for describing datasets.
  • files are not replicated, so storing in the staging area doesn't prevent data loss in case of a major hardware failure. Single disk failure will not cause data loss.

Frozen area is intended for storing stable research data in an immutable state. In the frozen area

  • files will be given unique Ids, checksums, and their metadata stored in the metadata repository
  • files will be replicated on another media
  • files will be visible to the coming services supporting digital preservation to be launched in mid-2018

Data should be moved to the frozen area once no further changes are expected to be made. Data in the frozen area is available to new services supporting digital preservation and they can be included as a part of user-defined dataset after the lauch of these services mid-2018.

All project members can move data from the staging area to the frozen area. Because of the procedures for data preservation, data in the frozen area can not be re-arranged, renamed or overwritten. Frozen data can moved back to the staging area or deleted entirely from the service, but users should be aware of the effects of these measures. If data is moved back to the staging area or deleted, the unique file IDs and file metadata will be discarded. This means that any references to those files within any defined datasets and download links to data will become permanently invalid. This applies also to the referencies and download links made before the IDA renewal.

During the spring of 2018, users can continue to describe datasets using Etsin, but adding direct download links to data in IDA is not available. Users will again be able to describe and publish datasets with direct download links to files in IDA in mid-2018, using the new services supporting digital preservation which will be launched at that time.

Please notice, that IDA's frozen area is not long-term preservation. The service for long-term preservation for research data (TPAS) is a separate service, which will be launched later in 2018.

  Project's staging area Project's frozen area
Intended use Collecting and organizing research data in preparation for frozen storage. Data can be added, moved, renamed, and deleted freely by all project members. Storing stable research data in an immutable state.  Data can only be unfrozen or deleted. Data is available to other services supporting digital preservation mid-2018.
Users can upload, rearrange, overwrite files and directories  
Users can download and delete files/directories
Users can share data with temporary links
Suitable for publishing data via Etsin mid-2018 (permanent download links)  
File metadata saved in metadata repository  
Checksums calculated for files  
Files have unique IDs  
Files replicated on another media (recovery from major hardware failure)
