As educational technology becomes pervasive, demand will grow for library content to be incorporated into courseware. Among the barriers impeding interoperability between libraries and educational tools is the difference in specifications commonly used for the exchange of digital objects and metadata. Among libraries, METS is a new but increasingly popular standard. the IMS Content-Package (IMS-CP) plays a parallel role in educational technology. We describe how METS-encoded library content, can be converted into digital objects for IMS-compliant systems through XSLT-based crosswalks. We compare the conceptual models behind METS/MODS and IMS-CP/IMS-MD, document the design and limitations of an XSLT-based translation, and relate the crosswalks to other techniques to enhance interoperability.
