Twinbase: Open-Source Server Software for the Digital Twin Web

Digital twins are expected to form a network, “Digital Twin Web”, in the future. Web follows similar structure World Wide and consists of meta-level digital that described as twin description documents distributed via TwinWeb servers. Standards must be established before can used efficiently, having an easily accessible server implementation foster development those standards. Twinbase is open-source, Git-based developed with user friendliness mind. stores Git repository, modifies them workflows, distributes users static web server, from which accessed client library or regular browser.
