File Types/Sizes

Answer: There aren’t any limits on file sizes. However, if they are really large, then contact us and we will work with you on a solution to upload these taking into account connection speed, bandwidth, etc.

Answer: The Common Cartridge option is not a requirement but it can improve the ability of others to reuse your materials. The Common Cartridge option may be a plug-in your LMS administrator will need to add to get the export option for Common Cartridge. A Common Cartridge captures the application files, assessments, web links, and discussion topics in an LMS course for easy import into any other compliant LMS. Here is information about Common Cartridge :

You can upload the LMS export file of the OER materials to the SkillsCommons repository for now.

Answer: To enable others to easily access and work with all CCBY-licensed content, content should be made available in a file format that allows anyone to natively and directly edit the content. For CCCS-licensed content, closed file formats are acceptable. Content may be made available in multiple formats, but at least one of these formats must be openly editable by providing the original file format used to create the content. The type of file format varies by type of media:

For documents: Openly editable formats include original Microsoft Office files (e.g., doc, .docx., .ppt, etc) and other editable document files. An example of a closed document format is a PDF, since files with the .pdf extension do not allow edits.

For images: Source files should be shared for images (e.g. Adobe Photoshop), video clips, or Flash (such as FLA). 

For video: Common video formats include MP4 (H.264), MOV, OGM, WEBM, FLV, and AVI

For audio: Common audio formats include MP3, OGG, FLAC, and WAV, Theora and MP4. For audio-only files, exporting to OGG Vorbis and MP3 is recommended. Include high-resolution versions of videos where possible.


Answer:  Given the broad availability of Microsoft Word®, you can upload the material in the .doc or .docx format, so that other people can edit the original with full fidelity.
