The Humboldt Digital Library: Exploring Innovative Structures

4. Testbed for data communication

The request for information from Internet is managed by the Humboldt portal, which offers a graphical user interface, depending on predefined user profiles. This structure offers search for text information on different paths. The first path is the search for text passages, keywords and themes. It leads directly to a text presentation of texts. Another option is to search by a specific date or location in Humboldt’s travel entries. Using the spatial data engine, the user will have access to a variety of map layers. The user can use the maps for zooming in, check for locality names, search for topics in the legend to find points o interest. The result can be presented as a map or a text paragraph in the Web page.

The connection between the text and spatial data will be established by interactive maps, containing graphical objects with attributes. The focus will be on the identification of text attributes in the database and the definition of hyperlinks to access the archive.

To be able to compare Humboldt’s insights with what is known today, it is necessary to allow the user to navigate outside the system to other relevant data banks and return. Thus, the Humboldt digital library needs to be more than a collection of static images with hyperlinks. Only a dynamic system can accommodate navigation among independent data banks and can accomplish the diverse tasks we have outlined.

The consequences of the concept are dealing with search functions in the three dimensional scale, containing predefined keywords as well as a network of information, which is established on the basis of definitions of synonyms to existing keywords no matter of languages, spellings, or kind of texts.
