The proliferation of online teaching, learning, and assessment resources is hampering efforts to make finding relevant resources easy. Metadata, while valuable for curating digital collections, is difficult to keep current or, in some cases, to obtain in the first place. Social metadata, paradata, usage data, and contextualized attention metadata all refer to data about doing with digital resources that can be harnessed for recommendations. To centralize this data for aggregation and amplification, the Learning Registry, a store and forward, distributed, de-centralized network of nodes was created. The Learning Registry makes it possible for disparate sources to publish learning resource social/attention metadata—data about users of and activity around resources. We describe our experimentation with social metadata, including that which describes alignment of learning resources to U.S. teaching standards, as a means to generate relationships among resources and people, and how it can be used for recommendations.
