Based on such a system, it becomes possible to create automatically a simple interface guiding the user towards any of the services described in the dictionary. This idea has been developed as a prototype tool, under the name of AstroGLU , in order to demonstrate the feasibility of the concept, convince more data providers to collaborate, and help orienting future developments in the domain. But the user does not need to have an a priori knowledge of the existing services, or even of the information types corresponding to potential query results. But the focus is made on the first aspect, the second one being generally kept implicit until the selection of the information type is done. The user can finally select one of the proposed services, and will receive a form for submitting the query to the remote service, to which it is finally submitted for processing.
AstroGLU functionality is constructed around the main dictionary.
At the end, they are sorted in alphabetical order. Step 3 may include, in the future, examples and default values of additional parameters. The complete list of actions can be displayed on request. AstroGLU can be automatically implemented for all or part of the domains cooperating to the GLU system. All the forms are generated from the GLU Dictionary information.
