This 1EdTech standard aims to facilitate the discovery and retrieval of learning objects stored across multiple collections. In the context of this work, a learning object can be anything digital used for teaching, learning, or training. Learning objects can consist of simple assets (e.g. text, images, short videos) that can, in general, be rendered directly in a web browser, or more complex resources that usually consist of multiple components (e.g. text, images, simulations, videos, assessment exercises, etc.) that need to be combined in a precise way to provide end-users with a meaningful learning experience. Learning content specifications such as Content Package and Common Cartridge make it possible for such learning objects to be reused in different learning systems. This is achieved by packaging all the required components in a zip file together with a manifest describing how these components have to be rendered. As a result of this process where specifications have been applied, the content becomes more 'interoperable' and can be more easily exchanged and reused in learning platforms from different commercial vendors or in open-source learning (content) management systems that comply with the relevant content packaging specifications. The LTI Resource Searchspecification has superseded this work, and so the LODE standard SHOULD NOT be adopted.
