Use more consistent property names for stored objects

[jfroelich]

• Some property names use a type suffix or prefix, but others do not. Consistently use a prefix or do not use one at all, or at least somehow articulate why behavior diverges
• Some property names use a type suffix, and some use a prefix. It would be better to always use a prefix, or always use a suffix, and not jump back and forth erratically. I think it would be better to always use a suffix.
