metadb-core v2.0.0

metadb-core

metadb is a peer-to-peer media file metadata database and file-sharing program. Peers can extract information about their media files and replicate this data with other peers, to build a searchable distributed database of all known files.

This module contains the core functionality - the distributed index and file transfer.
