For a general overview of a deployment setup please refer to the System Architecture.

Corporate Memory¤

A minimal single-node deployment for testing/evaluation purposes means:

Depending on how much RAM is dedicated to the triple store, Knowledge Graphs up to several million triples can be built and served.

Operating System / Hardware
- Bare metal server or VM with Ubuntu or RHEL linux OS (see Installation for details)
- 16 GB RAM
- 100 GB free disk space (10 GB for docker images + data + logs over time)
- docker and docker-compose (we deliver an orchestration including all needed components)
Triple / Quad Store
- Stardog 7.4.x
- Ontotext GraphDB
- OpenLink Virtuoso Open Source
Identity Management (delivered with orchestration)
- Keycloak >= v6.0.1
- PostgreSQL >= v11.5
Proxy Server (delivered with orchestration)
- Apache >=2.4 (incl. rewrite and other modules)

For an example of a single-node installation refer to the following scenarios:

In a typical deployment all components are installed on separate VMs (nodes). Therefore, six separate VMs are required.

The following numbers are based on existing customer deployments running Knowledge Graphs up to 300 million triples with 40 concurrent users.

We support all (LTS/ESR) versions of the below listed browsers that are actively supported be the respective publishers:

Note

Internet Explorer 11 as well as Safari Browser are not officially supported. IE11 is reported not to work.

For cmemc, currently Python 3.9 is supported, but Python 3.10 is reported to work as well.

There is also a docker image available.
