3. Main Message Digital libraries can help advance education. Chile is invited to engage in NSDL, CITIDEL, NDLTD, and other ventures. UNESCO Analytical Survey on Digital Libraries in Education is recommending DLE in each nation. Local and national support can stimulate activities, including collaboration promote a sharing culture, especially in research and teaching leverage others’ investments (networking, computing, …) encourage / facilitate learning, innovation and problem solving

8. Metadata vs. Data Data refers to digital objects or digital representations of objects Metadata is information about the objects (e.g. title, author, etc.): descriptive, interpretive, administrative, … Many digital library efforts, including the Open Archives Initiative (OAI), focus on metadata, with the implicit understanding that metadata usually contains useful links to the source digital objects Purists would argue metadata is just data

NDLTD Members and ETD-MS NDLTD members will Share metadata for their ETDs Providing that in either ETD-MS Or if they use a version of MARC locally, work to have that eventually shared in either MARC21 or UNIMARC Run OAI, either locally or in consortia, so their metadata can be harvested, according to necessary terms and conditions

48. CS Teaching Center (CSTC) Instead of building large, expensive multimedia packages, that become obsolete and are difficult to re-use, concentrate on small knowledge units. Learners benefit from having well-crafted modules that have been reviewed and tested. Use digital libraries to build a powerful base of support for learners, upon which a variety of courses, self-study tutorials & reference resources can be built.
