AtomGraph/LinkedDataHub

The low-code Knowledge Graph application platform. Apache license.

What it solves

LinkedDataHub (LDH) addresses the complexity of managing and publishing Linked Data. It provides a low-code environment for researchers and developers to create applications, manage data, and build visualizations directly on RDF Knowledge Graphs without needing to write imperative code like Java or JavaScript.

How it works

LDH uses a data-driven architecture where applications and documents are defined as data. It provides a generic HTTP API and a declarative framework for building user interfaces. Users can edit XHTML documents in-place using an RDFa-aware rich text editor, which allows them to link text directly to Knowledge Graph terms. The platform supports multiple "dataspaces" on a single instance, each with its own admin and end-user applications, and can optionally mirror document history to a GitHub repository for auditability.

Who it’s for

  • Researchers who require an RDF-native, FAIR-compliant data environment for collecting and consuming Linked Data.
  • Developers seeking a declarative full-stack framework that includes out-of-the-box UI and API components for Knowledge Graph applications.

Highlights

  • Low-code platform for managing RDF Knowledge Graphs.
  • Data-driven architecture where apps are defined as data.
  • Built-in RDFa-aware rich text editor for semantic content creation.
  • Optional GitHub integration for graph versioning and audit trails.
  • Supports multiple dataspaces per instance with customizable UI and API.
  • Available as a pre-configured AWS Marketplace product.

    Roboflow‑python is the official Python client for the Roboflow computer‑vision platform. It lets you programmatically create workspaces/projects, upload and version datasets, trigger model training, and run inference on hosted or self‑hosted models. Install via `pip install roboflow` (or the lightweight `roboflow-slim`), authenticate with an API key or login, and use a simple object hierarchy (workspace → project → version) to manage the full CV lifecycle.
