Potential areas of synergy : IVOA and IPDA Some IVOA “generic” protocols, already used in Planetary area VOTable (used by PDAP) SAMP – Simple Application Messaging Protocol TAP – Table Access Protocol Need for updates to better address IPDA needs ? Commonalities amongst Data Access Protocols SIAP, TAP, SSAP?, SLAP? PDAP Commonalities for IVOA and IPDA Resources Registries ? Other potentially useful IVOA “generic” protocols VOSpace ? Utypes ?
