Notes

• Protocols VOSpec is using (SSAP and SLAP) are UTYPE-based, so the use of UCDs is secondary

• UNITS DM draft is partially based in the Unit object used in VOSpec

• VODataService is used in the Registry query• Resource identifier is internally used to distinguish the

Registry records • CharDM is indirectly used in two ways: when reading

SSAP responses, and using the SED library, that has Characterization objects

• (There is an implementation of a connection between VOSpace and VOSpec, but currently disabled)
