Science Operations & Data Systems Division Research & Scientific Support Department IVOA Tutorial Strasbourg 2003 9 Pedro OSUNA Conclusion You can adapt your existing archive to IVOA-SIAP and other IVOA protocols (1D Spectrum?,…) Easiness depends on archive architecture: three- tier architecture is a good approach Use Translation Layers: they are worth for flexibility and adaptability. Do not need to force your database to use UCDs but you ought to translate to them (see Unified Content Descriptor v2.0 document) Jsp/Servlets/Java has proven to be a good suite for developing this type of application
