Going through there docs I came to know that "CATA's Metadata Engine, Minerva, is released now!".

Its a data query engine built upon a combination of three co-operating components: Qri- the data management tool, Drill- the distributed query engine, and IPFS- the storage backend. (source)

Thats a good news. We need to learn more such news to get familiar with whats going on.
Minerva is back bone on CATA. It takes benefit of flexibility of Drill’s query engine and the scalability facto of IPFS's filesystem which is decentralized. Every user of Minerva has a local node, and the Minerva nodes form a peer-to-peer network. A user who has a particular dataset in her local store is a provider for that dataset, and can accept queries about it from other users in the network.
