The reference provider currently supports Bitswap and Filecoin protocols. The structure of the
metadata format for these protocols is defined
in [the library](https://github.com/filecoin-project/index-provider/tree/main/metadata).
in [the library](https://github.com/ipni/go-libipni/blob/main/metadata).

The network indexer nodes expect that metadata begins with a `uvarint` identifying the protocol,
followed by protocol-specific metadata. This may be repeated for additional supported protocols.
Specified protocols are expected to be ordered in increasing order.
