At the heart of the LTI Resource Search standard is agreed upon (defined) metadata. LTI Resource Search offers a powerful way to improve the search experience for teachers and students by defining specific search terms or metadata fields. This metadata can be associated with learning objects in a repository or catalog using Resource Search. The specific vocabulary to use within each field is defined in the Resource Search Specification.
The special filter attribute “search” allows powerful retrieval from the name, description, learning objective, and subject fields.
The list of metadata available in LTI Resource Search is described in detail within the specification documentation. Here is an overview of the metadata fields included in Resource Search.
