LRMI

LRMI stands for Learning Resource Metadata Initiative. It is a metadata schema designed to describe educational resources to improve discovery, interoperability, and reuse across catalogs, repositories, and search engines. LRMI is an extension of the schema.org vocabulary and is intended to be compatible with related standards such as Dublin Core, enabling consistent metadata practices across platforms.

Purpose and scope

LRMI provides a set of descriptive properties tailored to education, capturing information relevant to learners, educators, and librarians. Typical use cases include identifying the intended audience, the educational level or age range, the expected learning outcomes, and how the resource should be used. It also supports indicating alignment with educational standards or frameworks and the estimated time required for engagement with the resource.

Key properties

LRMI introduces and clarifies properties such as educationalAlignment, typicalAgeRange, educationalLevel, learningResourceType, timeRequired, and interactivityType. When used, these properties are often embedded within schema.org structured data on web pages or in metadata records for learning objects, allowing automated agents to interpret and filter resources effectively.

Impact and adoption

LRMI is used in digital libraries, school portals, and learning platforms to enhance search, discovery, and filtering of educational content. Its alignment with schema.org improves visibility in mainstream search engines and supports interoperability between repositories and catalogs.

Governance and history

LRMI originated as a community-driven effort to standardize descriptions of learning resources. Development and maintenance are carried out by a collaborative ecosystem that coordinates with schema.org’s education-related extensions, reflecting evolving practices in educational metadata.
