The CDS has recently developed a tool for managing URLs in a context of distributed heterogeneous services (GLU, Uniform Link Generator: Fernique et al. 1998). This includes the development of a `URL dictionary' maintained by the data providers contributing to the system. Based on such a system, it becomes possible to create automatically a homogeneous interface to the services described in the dictionary. This tool is currently available as a prototype, under the name of AstroGLU, with the aims of demonstrating the feasibility of the concept, and helping orienting future developments in the domain. Being a flexible, easily maintainable tool, AstroGLU is a strong incentive for an increased cooperation of all astronomical data providers.
