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.
We use an advanced git-like model storing append only changes to graphs represented in concise datastructures using terminus-store.
v1.1.1
For Linux we recommend you use our Quickstart installer.
To install a docker image with the latest server follow the instructions here: running the terminus-server from docker.
In order to build from source, follow the build from source directions.
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/console". (for instance "http://localhost:6363/console").
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...
- Now with our own terminus-store backend!
- Extended WOQL to greater functionality for string and arithmetic processing
- Better date handling in WOQL
- Improved type casting in WOQL
- Improvements to query processing speed
We are working hard on our collaboration and data-ops features. They should be available by the end of February 2020.
- Improve error handling and logging
- Convert frames into valid JSON-LD
