In an effort to achieve better, more seamless exchange of metadata between libraries and related applications, Dublin Core Metadata Initiative (DCMI) proposes a new application profile.
The application profile draws together subsets of elements, qualifiers and permitted schemes and values of existing DCMI metadata standards. Not only that, it also provides support for additional subject specific schemes like those listed or defined by the American MARC library catalog system. The end result of such an application profile is that it is much more specific to the subject and narrow in what it allows than the more general DCMI specification, at the inevitable cost of a more narrow applicability.
The specific uses that the library application profile is created for range from the interchange of data between libraries and related systems in a variety of standardised formats, metadata harvesting and support for the creation of library records within a variety of environments. Most interesting from the elearning perspective is support for exposing MARC metadata to non-library communities, and the possibility for libraries to acquire DC based resource discovery metadata back from other communities into libraries. The upshot is that the application profile could provide a well-circumscribed means to discover learning content in and through library systems.
