  9. 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
