Conclusion
•You can adapt your existing archive to IVOA-SIAP
and other IVOA protocols (1D Spectrum?,…)
•Easiness depends on archive architecture: threetier 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
