The International Standard Content Code is an open standard for decentralized content identifiers. This repository contains the specification of the ISCC Standard and a reference implementation in Python3. The latest published version of the specification can be found at iscc.codes
Installing the reference code
The reference code is published with the package name iscc on Python Package Index. Install it with:
pip install isccUsing the reference code
A short example on how to create an ISCC Code with the reference implementation.
import iscc
# Generate ISCC Component Codes
mid, title, extra = iscc.meta_id('Title of Content')
cid = iscc.content_id_text('some text')
did = iscc.data_id('path/to/mediafile.doc')
iid, tophash = iscc.instance_id('path/to/mediafile.doc')
# Join ISCC Components to fully qualified ISCC Code
iscc_code = '-'.join([mid, cid, did, iid])
print('ISCC:{}'.format(iscc_code))Working with the specification
The entire ISCC Specification is written in plain text Markdown. The markdown content is than built and published with the excellent mkdocs documetation tool. If you have some basic command line skills you can build and run the specification site on your own computer. Make sure you have the Git and Python installed on your system and follow these steps on the command line:
git clone https://github.com/iscc/iscc-specs.git
cd iscc-specs
pip install -r requirements.txt
mkdocs serveAll specification documents can be found in the ./docs subfolder or the repository. The recommended editor for the markdown files is typora. If you have commit rights to the main repository you can deploy the site with a simple mkdocs gh-deploy.
