Currently we are storing the whole of the json into the Database inside of OffChainVoteDataJson / offchainvote table
which happens around here:

cardano-db-sync/cardano-db-sync/src/Cardano/DbSync/OffChain.hs

Lines 115 to 118 in c5d6b8a

    
           insert :: (MonadBaseControl IO m, MonadIO m) => OffChainPoolResult -> ReaderT SqlBackend m () 
        
           insert = \case 
        
             OffChainPoolResultMetadata md -> void $ DB.insertCheckOffChainPoolData md 
        
             OffChainPoolResultError fe -> void $ DB.insertCheckOffChainPoolFetchError fe

current functionality was introduced in this PR

TLDR currently we:

fetch offchain metadata
put it into DB inside OffChainVoteDataJson

What we'd ideally like is:

fech offchain metadata
parse metadata
put parsed metadata into a new table with same structure as the parsed type
link newly created row id in OffChainVoteDataJson which is currently of the typeText

We can get the expected structure from cardano-foundation/CIPs#632 once it is merged and finalised.

An initial implementation of this is done at sancho-4-1-0

	insert :: (MonadBaseControl IO m, MonadIO m) => OffChainPoolResult -> ReaderT SqlBackend m ()
	insert = \case
	OffChainPoolResultMetadata md -> void $ DB.insertCheckOffChainPoolData md
	OffChainPoolResultError fe -> void $ DB.insertCheckOffChainPoolFetchError fe
