The International Standard Content Code (ISCC) is a similarity preserving identifier for digital media assets.

ISCC-CODEs are generated algorithmically from digital content, just like cryptographic hashes. However, instead of using a single cryptographic hash function to identify data only, the ISCC uses various algorithms to create a composite identifier that exhibits similarity-preserving properties (soft hash). ISCC-CODEs can also be registered using a decentralized protocol to obtain a short, unique and resolvable ISCC-ID.

iscc-did-driver is a service application that resolves Decentralized Identifiers (DIDs) for the ISCC DID method based on the W3C DID Core 1.0 and DID Resolution specifications.

The service provides a REST API for resolving did:iscc identifiers sourced from public ledger registrations. The service can be run standalone or plugged in as a driver for the DIF Universal Resolver.

A public instance with interactive API documentation is available at https://did.iscc.id.

The service is configured via environment variables:

• ISCC_DID_DRIVER_DEBUG - Run the service in debug mode (default: False)
• ISCC_DID_DRIVER_REGISTRY - URL to an ISCC registry instantiation (default: https://iscc.id)
• ISCC_DID_DRIVER_SENTRY_DSN - Optional connection string to sentry.io for error reporting (default: "").

An enviroment configuration placed in a .env file in the working directory will be automatically loaded at application startup.

Requirements:

• Python 3.8 - 3.10
• Poetry

Get up and running with:

git clone https://github.com/iscc/iscc-did-driver.git
cd iscc-did-driver
poetry install
python -m iscc_did_driver.main
