 Express based Web Server that exposes [Linked Connections](http://linkedconnections.org/) data fragments using [JSON-LD](https://json-ld.org/) serialization format. It also provides a built-in tool to parse [GTFS](https://developers.google.com/tansit/gtfs/reference/) and [GTFS Realtime](https://developers.google.com/transit/gtfs-realtime/) transport dataset feeds into a Linked Connections Directed Acyclic Graph using [GTFS2LC](https://github.com/linkedconnections/gtfs2lc) and fragment it following a configurable predefined size.
