The document discusses building a linked data application for learning resource recommendations. It describes the vision of creating an ecosystem of interconnected learning data from institutions around the world. It outlines some early progress made, including building basic ontologies and linking existing data sources. However, it notes that more work is still needed to fully connect resources and infer relationships. The document also covers some lessons learned, such as the importance of sustainability, provenance, licensing and reliability when creating applications using linked open data.
