TerminusDB is an open-sourcegraph database. It is designed for collaboratively building and curating knowledge graphs. It is a nativerevision control database that is architecturally similar to Git and other distributed version control systems. TerminusDB's is also a document store and a RDF store (as listed on DB-Engines[3]).

Data collaboration is facilitated through TerminusHub, which is a freemiumSaaS that allows users to manage access to databases and collaboratively work on shared resources.

TerminusDB is available under the permissiveApache 2.0 license.[4] The development team claim that it will be 'open source now and forever'.[5] TerminusDB is implemented in Prolog and Rust and accessible using a transactional HTTP endpoint. TerminusDB uses JSON-LD as a lightweight, language-independent data interchange format.

History[edit]

DataChemist[edit]

TerminusDB, previously known as DataChemist,[6][7][8] was founded in Dublin, Ireland. It was launched by Irish TánaisteSimon Coveney in August 2018.[9] TerminusDB opened a research and development hub in Utrecht, Netherlands in 2019.[10]

ALIGNED Project[edit]

Starting in Trinity College Dublin,[11] the development team behind TerminusDB ran the Horizon 2020 project ALIGNED that worked from February 2015 to January 2018.[12][13][14] An open-accesse-book entitled Engineering Agile Big-Data Systems was published on completion of the ALIGNED project[15]

Seshat[edit]

Seshat is an international scientific research project of the nonprofitEvolution Institute which uses TerminusDB as data infrastructure.[16] Seshat has been working with the development team from the ALIGNED project onward.[17] This work has been reported in several major newspapers.[18][19] TerminusDB is also the database behind the associated Institute for Economics and Peace and Oxford Universityhistorical peace index project.[20]

The results of some aspects of this research, focused on the relationship between complex societies and moralizing gods, appeared in Nature,[21] the prestigious scientific journal. Kevin Feeney, one of the founders of TerminusDB, is an author of the paper and sits on the Board of directors of Seshat.[22]

Open source[edit]

Terminus Github

Version 1.0 was released in October 2019.[23] TerminusDB was first released under the GPLv3 licence with the client libraries are released with the Apache 2 licence. TerminusDB 1.1, with the newly integrated terminus-store, was released in January 2020.[24] Version 2.0 of the database was released in June 2020[25] and 3.0 was released in July 2020.[26] Version 4.0 was released in December 2020[27] under the Apache 2.0 license. The shift was discussed extensively.[28]

Name[edit]

TerminusDB is named after the Roman God of Boundaries, Terminus. It is also named after the home planet of the Foundation in the series of science-fiction novel by Issac Asimov.[29] TerminusDB uses a CowDuck mascot - the motif finds its origins in the examples used by core engineer Matthijs van Otterdijk when first demonstrating the append only immutable data store[30]

Main features[edit]

TerminusDB is a full featured in-memory graph database management system with a rich query language. The design of the underlying data structure, which is implemented in a Rust library, uses a succinct data structures and delta encoding approach drawing inspiration from software source control systems like Git.[31] This allows all of the Git semantics to be used in TerminusDB.

The TerminusDB infrastructure is based on the RDF standard. This standard specifies finite labelled directed graphs which are parameteric in some universe of datatypes. The names for nodes and labels are drawn from a set of IRIs (Internationalized Resource Identifiers). TerminusDB uses the XSD datatypes as its universe of concrete values. For schema design, TerminusDB uses the OWL language with two modifications to make it suitable as a schema language; it dispenses with the open world interpretation and insist on the unique name assumption.[32] This provides a rich modelling language which enables constraints on the allowable shapes in the graph. TerminusDB supports a subset of OWL that provides for the following schematic control features:

  1. Classes and sub-classes for modelling taxonomies and inheritance hierarchies, with special classes for modelling complex relationships and entities
  2. Typed properties for modelling the attributes of things
  3. Datatypes for modelling the different types of data
  4. Scopings for modelling things that change with time, space and confidence
  5. Constraints for applying logic and rules to things[33]

TerminusDB has a promise based client for the browser and node.js it is available through the npm registry, or can be directly included in web-sites.[34] It also has a Python client for the TerminusDB RESTfulAPI and the pythonic version of the web object query language, WOQLpy.[35]

Query language[edit]

WOQL (web object query language) is a datalog-based query language. It allows TerminusDB to treat the database as a document store or a graph interchangeably, and provides query features to make relationship traversals easy. WOQL's primary syntax and interchange format is in JSON-LD. This gives a relatively straightforward human-readable format which can be easily stored in TerminusDB itself.

Example[edit]

This demonstrates a simple query which creates a document in the database, along with labels and cardinality constraints.[36]
