+- Publisher NFTs are Metaplex Certified Collection (MCC) NFTs that have can have many "apps" associated with them.
+- App NFTs are _also_ MCC NFTs that can have many "releases" associated with them.
+- Releases are immutable Metaplex NFTs that can only be issued once per-version. Any new releases must be re-issued as a new NFT.

+All releases for a dApp store entry will be grouped under an "App" collection, which itself will be an NFT that contains JSON metadata representing “global” immutable data for a dApp’s catalog entry. This actually ends up being just _one_ extension property, the app package name.
