Terminus Server

Build Status

TerminusDB is an open source model driven graph database for knowledge graph representation designed specifically for the web-age.

Terminus Server provides TerminusDB with a RESTful API for interacting with knowledge graphs via the JSON-LD exchange format. This means you can easily string together applications within your own toolchain which utilise the powerful features of graph search and graph storage.

Latest Version


Getting Started

Install from Docker image

To install a docker image with the latest server (RECOMMENDED) follow the instructions here: running the terminus-server from docker.

Building from source

In order to build from source, follow the build from source directions.

Open Dashboard

One you have installed terminus-server either from the docker image or built from source you can go simply enter the server location into your browser to view your database from the dashboard "http://SERVER:PORT/dashboard". (for instance "http://localhost:6363/dashboard").


Microservices API

Terminus Server is organised to be web native which means that all actions and activities are easily automated via a RESTful JSON-LD API.

The Server API is documented here.


WOQL, the Web Object Query Language, allows you to seemlessly traverse the graph extracting graph fragments, nodes, tables or JSON-LD documents. The syntax itself is in JSON-LD, making the syntax a native data-structure in JavaScript, Python, and Prolog.

The Syntax is documented here.


TerminusDB will:

  • Make complex data models easy, maintainable and enforced.
  • Overcome the Object Impedance mismatch without turning your Database into an incomprehensible soup.
  • Allow you to search for repeating patterns using recursion.
  • Give you powerful temporal queries using finite domain constraint logic.
  • Enable the sharing of data using linked open data formats RDF and JSON-LD making scientific or organisational information sharing easy.
  • Help you automate the production of UI and data-entry by knowing what data means.


In order to begin manipulating and querying your database you can simply point your browser to TERMINUS_DIR/index.html which should allow you to manage and query your database.

You can also perform all configuration, querying and management functions via the RESTful API. We have a number of client libraries to help you get started:

The JavaScript client libraries give you assistance with programatic access.

The JavaScript dashboard is an example application allowing manipulation of the database, queries and .

The [Python client libraries] Coming Soon...

Changes in this Version

  • Added additional typing information and documentation
  • Added database bootstrapping for access permissions and controls using the capabilities ontology
  • Added database initialisation utility
  • Added code for instance and schema checking


We are eagerly awaiting the release of our new highly scalable lock-free storage layer, terminus-store, which will be integrated into Terminus-server in a future release.


  • Write tests for Document API
  • Add optimisations to document expansion in JSON-LD avoiding duplicate expansions
