Admin
The data models produced by the tools in the Admin category relate to scraping the chain, producing the Unchained Index, and querying the configuration of the system. Additional data related to sharing the indexes via IPFS and pinning the same are also produced by tools in this category.
Each data structure is created by one or more tools which are detailed below.
Status
The status data model is a complex beast. It contains various information including a list of
registered chains, information about many of the internal binary caches maintained by chifra
as well as current status information about the system including version information for both
chifra and the node it’s running against.
The following commands produce and manage Status:

Manifest
The Manifest details the portions of the index of appearances which are called ChunkRecords. Each record in the Manifest details the block range represented by the chunk as well as the IPFS hash of the index chunk along with the associated IPFS hash for the Bloom filter of the chunk. The manifest itself is also pushed to IPFS and the IPFS of the hash of the manifest is published periodically to the Unchained Index smart contract.

ChunkRecord
The TrueBlocks index scraper periodically creates a chunked portion of the index so that it can be more easily stored in a content-addresable data store such as IPFS. We call these periodically-created chunks ChunkRecords. The format of said item is described here.
