The project Learning Resource Metadata Initiatitive (LRMI) was begun in the the spring of 2011 with the initial goal of developing a set of properties and classes to augment Schema.org for description of learning resources. The initial work was led by the Association of Educational Publishers —- the 501(c)(3) division of the Association of American Publishers —- and Creative Commons, and was funded by the Bill & Melinda Gates Foundation and the William and Flora Hewlett Foundation. In the fall of 2014, curation and further development of the initial 1.1 specification was transferred to DCMI for stewardship and further development under the guidance of the LRMI Task Group (LTG).
Shortly after the transfer in 2014, the LTG published the 1.1 specification in fully conformant RDF followed by four concept schemes using the W3C's Simple Knowledge Organization System (SKOS) to provide values for key properties in the LRMI schema. The task group extended it's work to provide support for development of the Schema.org Course entity, and, most recently, the work of the Schema.org Educational and Occupational Credentials Community Group. Since 2018, the LRMI Task Group is represented on the DCMI Usage Board by Phil Barker.
Your interest in LRMI is very important for us. We value any comments, questions, and suggestions that you might have either on the LRMI project itself or on the LRMI metadata specifications for describing learning resources and related entities. Please feel free to contact us through "contact at dublincore.net". If you feel you can contribute to the development of LRMI, please enter any suggestions regarding either LRMI Terms or the LRMI vocabularies can be entered into the LRMI issue tracker on Github. The more feedback we get, the better we can improve our specifications.
