Meta inquiry middleware for distributed systems

Project description


jomiel is the meta inquiry middleware for distributed systems. It returns meta data for content on video-sharing websites (e.g. YouTube) and runs as a service responding to client inquiries.

Two core technologies serve as a basis for jomiel:

The client applications can be written in modern languages for most platforms.

jomiel is a spiritual successor to (now defunct) libquvi.

Example (jomiel)


  • Language and platform neutral messaging using Protocol Buffers and ZeroMQ

  • A plugin architecture for extending video-sharing website support

  • Authentication and encryption (CURVE and SSH)

  • Runs fully as a service

  • Highly configurable

Getting started

To install from PyPI:

pip install jomiel        # For the latest release

To run from the repository:

git clone
cd jomiel
pip install -e .

Once you have jomiel running, you can try sending inquiries with:

  • examples - the demo programs written in most modern languages
  • yomiel - the pretty printer for jomiel messages

Website coverage

To view the list of the supported video-sharing websites, type:

jomiel --plugin-list

The website coverage is still very limited.

  • Additional support can be added by writing new plugins
  • The plugin architechture is implemented in Python
  • Python is a fun and easy language to learn

See the src/jomiel/plugin/ directory for the existing plugins.

When you are contributing new plugins

  • Make sure the website is not dedicated to copyright infringement (be that they host the media or the link to it)

  • Make sure the website is not NSFW
