Styx is an experimental RDF database that works like a key/value store, where the keys are RDF IRI terms and the values are RDF datasets. It also exposes a subgraph iterator interface that lets you iterate over all the subgraphs of the database that match a given pattern.
You can use Styx as a Go module by importing github.com/underlay/styx. Alternatively, you can run in the background by building the package github.com/underlay/styx/api:
% cd api
% go build -o styx
% export STYX_PREFIX=http://example.com/
% ./styx
This will start an API server exposing get/set/delete via GET, PUT, and DELETE requests, and subgraph iteration over a websocket RPC interface.
Set the Styx database location by setting the STYX_PATH evironment variable. It will default to /tmp/styx.
Set the API port with STYX_PORT. It will default to 8086.
You also need to set the STYX_PREFIX variable to a string like http://... that all of the keys you'll set will start with. For example, setting STYX_PREFIX=http://example.com/ means that you'll be able to insert datasets with keys beginning with http://example.com/. It will default to http://localhost:${STYX_PORT}. You don't need this if you only ever use the default dataset.
