ISCC - Resources

The open-source software and live demos that make up the ISCC ecosystem. Everything below builds on ISO 24138:2024, the International Standard Content Code.

Looking for independent assessments, research, or press coverage? Those are collected on iscc.io/standard/adoption. The ISCC Foundation's own papers and talks are listed at iscc.io/foundation/publications.

Open-source ecosystem

Every repository below is developed in the open under the Apache-2.0 license.

Core components

iscc-coreStable Authoritative ISO 24138:2024 reference implementation. The low-level codec and fingerprinting algorithms that every ISCC build rests on. View on GitHub → iscc-sdkStable High-level Python toolkit adding media-type detection, metadata extraction, and content processing. The primary integration entry point. View on GitHub → iscc-schemaStable JSON Schema, JSON-LD contexts, and Pydantic models for ISCC metadata interoperability. View on GitHub → iscc-libBeta High-performance polyglot implementation of the ISO 24138:2024 core algorithms. A Rust core with bindings for Python, Java, Go, Node.js, WASM, and more, conformance-tested against iscc-core. View on GitHub → iscc-cryptoBeta Ed25519 signing, W3C Verifiable Credentials, and cryptographic verification for signed ISCC declarations. View on GitHub → iscc-sumBeta Fast single-pass CLI for Data-Code and Instance-Code generation in Rust with Python bindings, from the BioCodes project. View on GitHub →

Discovery infrastructure

iscc-webStable REST API service for ISCC generation. Powers the public web demo at web.iscc.io. View on GitHub → iscc-hubBeta Reference timestamping and declaration service. Issues ISCC-IDs with cryptographic receipts for public content declaration and discovery. View on GitHub → iscc-searchBeta Specialized multi-index similarity search with sub-millisecond retrieval for ISCC codes and SIMPRINTs. View on GitHub →

ISCC Semantic Codes

iscc-sctBeta Semantic Text-Codes built on deep learning. Generates SIMPRINTs for granular text matching across languages. A core pilot component. View on GitHub → iscc-sciBeta Semantic Image-Codes for visual content fingerprinting and similarity detection. View on GitHub →

Specifications & quality assurance

iscc-iepsDraft ISCC Enhancement Proposals documenting new features and algorithms that inform future ISO standardization. View on GitHub → twinspectStable Benchmarking framework for near-duplicate matching and similarity search across text, audio, image, and video content. View on GitHub →
Stable Production-ready, stable API, ISO-aligned where applicable Beta Feature-complete, API may change before v1.0, suitable for pilots Draft Proposal documents under discussion

Cover Matching Demo

Three million book covers from the Amazon Reviews'23 dataset, indexed and searchable through ISCC similarity matching.

ISCC Web Demo

Minimal web application for generating ISCCs directly in the browser. Live instance of iscc-web.

ISCC Playground

Interactive Hugging Face Space for exploring every ISCC-UNIT and inspecting how codes change as content changes.

BioCodes Imagewalk Demo

Interactive visualization of the proposed Imagewalk algorithm for robust bio-image traversal and ISCC-CODE generation.

Publications & talks

Third-party publications, assessments, and coverage of the ISCC are collected on iscc.io/standard/adoption. The ISCC Foundation, which maintains the standard, lists its own papers and talks and its press kit on iscc.io.
