FAQ Technical

Are there any deposit requirements?

You are responsible for ensuring the content you deposit in the Atrium aligns with preferred file formats, file naming conventions, and is accessible. You will also be required to provide descriptive information (metadata) about each item you deposit in the Atrium using the online submission form. 

File format requirements 

To promote reuse, interoperability, and long-term access, files should be deposited in open, non-proprietary file formats. Files should also be saved and stored in an uncompressed and unencrypted format. 

For example, text documents, such as Word (DOCX) or PowerPoint (PPTX), should be converted to PDF/A format prior to upload. 

Examples of preferred formats include:

Textual documents

  • NotePad  (.txt)
  • Rich Text Format ( .rtf)
  • PDF/A ( .pdf)
  • Open document text (.odt)
  • XML (.xml OR XHMTL)


  • JPEG 2000, JPEG (.jpeg)
  • TIFF version 6 uncompressed (.tif)
  • Raw image (.raw)
  • PDF/A (.pdf)

Video recordings

  • MP4

Sound recordings

  • MP3
  • WAV

If you are unsure about the long-term accessibility and readability of your file format(s), please contact us for guidance.  

File naming requirements 

When naming your files, please: 

  • Keep the length of the file name short but descriptive (< 25 characters) 
  • Use date format ISO 8601: YYYYMMDD. 
  • Use alphanumeric characters. Avoid special characters and accented characters. 
  • Include a version number if applicable 
  • Use capitals and underscores instead of periods, hyphens, spaces, or slashes. 

For example:  



File size limitations 

Individual files must be equal to or less than two gigabytes (2 GB) in size for successful upload. There is no specific upper limit to the number of files or total overall storage size that can be added to a record or collection in the Atrium. 

If individual files are larger than 2 GB or if you have a very large number of files to deposit, please contact us for assistance. 


Depositors are responsible for ensuring that all materials they deposit in the Atrium meet accessibility standards according to the Accessibility for Ontarians with Disabilities Act (AODA).  Guidance and resources in support of creating accessible digital materials can be accessed through the Digital Accessibility Resource Centre

You may also refer to the WebAim tutorials (Word, PowerPoint, PDF, Multimedia) for guidance on how to make your work accessible. Note that for textual documents, it is easier to modify the original format (e.g., Word or PowerPoint) than the PDF version. 

Please note that not all content housed in Atrium is fully accessible. If you would like to request an alternate version of any content in the Atrium, please contact us for support. 

How do I obtain usage statistics for my item?

Usage statistics are available for each record in the Atrium. To view the statistics, first navigate to your item. In the right menu bar under the Statistics section, select View Usage Statistics. You will be redirected to a new page that provides basic usage statistics, such as total views, total views per month, number of file visits, top country views, and top city views.
