PyBossa is an open source platform for crowd-sourcing online (volunteer) assistance to perform tasks that require human cognition, knowledge or intelligence (e.g. image classification, transcription, information location etc).

PyBossa was inspired by the BOSSA crowdsourcing engine but is written in python (hence the name!). It can be used for any distributed tasks application but was initially developed to help scientists and other researchers crowd-source human problem-solving skills!

PyBossa powers CrowdCrafting.org and ForestWatchers.net

Installing and Upgrading

Important: if you are updating a server, please, be sure to check the Database Migration scripts, as new changes could introduce new tables, columns, etc, in the DB model. See the `Migration Section`_ from the documentation

See installation instructions.

NOTE: The latest version uses M2CRYPTO and the pypi version has a bug that does not allow you to sign properly RSA keys, however it will install it perfectly well. For this reason, you will need to install it using this other version: pip install -e git+https://github.com/Hypernode/M2Crypto#egg=M2Crypto

Running Tests

Set SQLALCHEMY_DATABASE_TEST_URI e.g.:

SQLALCHEMY_DATABASE_URI = 'postgres://pybossa:pass@localhost/pybossa'

Then run the tests (requires nose):

nosetests -v test/
