The 1EdTech Content Packaging specification describes data structures that can be used to exchange data between systems that wish to import, export, aggregate, and disaggregate digital content and courses. 1EdTech content packages enable exporting content from one learning content management system or digital repository and importing it into another while retaining information describing the media in the content package and how it is structured, such as a table of contents or which web page to show first. This standard is focused on the packaging and transport of resources but doesn’t determine the nature of those resources. This is because the specification allows adopters to gather, structure, and aggregate content in an unlimited variety of formats. The 1EdTech Common Cartridge standard is derived from this standard. This 1EdTech specification is available as an ISO standard [ISO/IEC 12785].
