Learning objects are the digital files that are used to construct e-learning experiences,and repositories provide mechanisms to encourage their discovery, exchange,and reuse. Portals for On-line Objects in Learning (POOL) is a consortiumproject of the TeleLearning NCE to build a learning object repository scalable to thenational level. Funded in part by the CANARIE Learning Program, POOL effortshave resulted in the development of two focal technologies: POOL, POND andSPLASH, a distributed architecture for a peer-to-peer network of learning objectrepositories; and CanCore, a practical metadata protocol for cataloguing learningobjects. The authors conjecture that the technology of learning objects andrepositories is in an early phase of development and that significant evolution canbe expected as user communities form, protocols emerge for the functional linkingof these structures, and the underlying technology becomes less visible.
