Common Cartridge is a technical standard designed to enable the seamless packaging, distribution, and interoperability of digital learning content and assessments across various educational platforms. It defines a structured format that encapsulates resources such as HTML files, multimedia, quizzes, and metadata within a single ZIP file, adhering to a single manifest file that describe the content and how to consume it. This allows content creators, publishers, and institutions to export and import course materials efficiently between Learning Management Systems (LMS) and other tools, ensuring consistent rendering and functionality. By supporting features like rich media integration, assessment interoperability, and metadata for discoverability, Common Cartridge enhances the portability and reusability of educational resources, making it a vital standard for streamlining content management and delivery in digital learning environments across Europe and globally.

A conceptual data schema that defines the structure of a metadata instance for a learning object is specified in this standard. For this standard, a learning object is defined as any entity, digital or non-digital, that is used for learning, education, or training; a metadata instance for a learning object describes relevant characteristics of the learning object to which it applies. Such characteristics can be regrouped in general, life cycle, meta-metadata, educational, technical, educational, rights, relation, annotation, and classification categories. The conceptual data schema defined in this standard specifies the data elements of which a metadata instance for a learning object is composed and allows for linguistic diversity of both learning objects and the metadata instances that describe them. It is intended that this standard will be referenced by other standards that will define the implementation descriptions of the data schema, so that a metadata instance for a learning object can be used by a learning technology system to manage, locate, evaluate, or exchange learning objects. The intent of this standard is to specify a base schema, which can be used to build on as practice develops, for instance in order to facilitate automatic, adaptive scheduling of learning objects by software agents.

Learning Resource Metadata Initiative: Eine Sammlung von Klassen, Eigenschaften und Vokabularen, die zur Beschreibung von Bildungsressourcen genutzt werden. Die Vokabulare werden mit Hilfe des Simple Knowledge Organization Systems (SKOS) beschrieben. Die genutzten Klassen und Eigenschaften werden in schema.org integriert.

Learning Tools Interoperability (LTI), a technical standard developed by the 1EdTech Consortium, seamlessly connects external learning tool - like apps, assessments, or content - with platforms such as learning management systems (LMS). Finalized and adopted globally across K-12, and higher education, LTI enhances teaching and learning environments by enabling secure, single sign-on access without separate logins. It supports robust data exchange about users, their roles, and institutional enrollment, fostering an efficient, interconnected edtech ecosystem worldwide. The standard continues to evolve, with 16 extension specifications refining its capabilities.

Question and Test Interoperability (QTI) is a technical standard that facilitates the creation, exchange, and delivery of assessments, quizzes, and test items focused on learning outcomes, skills, and competencies across educational platforms. It incorporates a structured format to define diverse question types—such as multiple-choice, essays, or interactive tasks—along with scoring rules, feedback, and metadata, ensuring consistent performance in learning management systems (LMS) and assessment tools. QTI integrates support for Access For All and Personal Needs and Preferences, enabling personalized accessibility adjustments—like accommodations for visual, auditory, or motor impairments—aligned with individual learner needs and broader educational frameworks. Deployed heavily worldwide for high-stakes assessment scenarios, QTI ensures equitable access and fairness, allowing educators to align assessments with curriculum goals, share interoperable content, and effectively measure skill development in diverse, inclusive digital testing environments.
