- Abstract
- Within a digital library, collections may range from an ad hoc set of objects that serve a temporary purpose to established library collections intended to persist through time. The objects in these collections vary widely, from library and data center holdings to pointers to real-world objects, such as geographic places, and the various metadata schemes that describe them. The key to integrated use of such a variety of collections in a digital library is collection metadata that represents the inherent and contextual characteristics of a collection. The Alexandria Digital Library (ADL) Project has designed and implemented collection metadata for several purposes: in XML form, the collection metadatada 'registers' the collection with the user interface client; in HTML form, it is used for user documentation; eventually, it will be used to describe the collection to network search agents; and it is used for internal collection management, including mapping the object metadata attributes to the common search parameters of the system

- Abstract
- Based on a decade's experience with the Alexandria Digital Library Project, seven issues are presented that arise in creating georeferenced digital libraries, and that appear to be intrinsic to the problem of creating any library-like information system that operates on georeferenced and geospatial resources. The first and foremost issue is providing discovery of georeferenced resources. Related to discovery are the issues of gazetteer integration and specialized ranking of search results. Strong data typing and scalability are implementation issues. Providing spatial context is a critical user interface issue. Finally, sophisticated resource access mechanisms are necessary to operate on geospatial resources.
