inventaire *means "inventory" in French

  • keep an inventory of your books

    and of what can be done with them: "this book I can lend, this book I can give, this one is for sell..."

  • share it with your friends and communities

    Always dreamed of a collaborative library for your coworking / association / book club? Here it is!

  • Remember the books you lend or borrow

    The books you lend might actually come back now!

our mission & values

  • Empowering the Transition

    This is an experiment about resources and capabilities. Given a resource you have or you look for, what are your possibilities? Make, give, get from a gift, lend, borrow, rent, buy, sell, upcycle, recycle... The goal of the Inventaire project is to map those possibilities, make alternatives visible. At the same time, this is about easing resources data transparency and openness, and the transmission of those data from the business to the customer.

  • Just Books. For now.

    That's already a wide program isn't it? Let's start small: just mapping books in your network or nearby, available for giving, lending or selling. Peer to peer first, but integrating local libraries and local booksellers in the map as soon as possible.

  • Built on and for Open Knowledge

    Information on resources should be free and open for citizens to be empowered in their daily choices. What if our daily interactions with resources, our transactions, were contributing to make everyone's knowledge on those resources grow? Inventaire is an experiment to make a step in this direction, starting by using Wikidata - the awesome public database gathering facts for Wikipedia - as a starting point to gather data on resources. All public data gathered in Inventaire will be published under an open licence.

  • Built on and in Open Source

    Closed centralized systems grow dependency and lock-in the user in this system, while contributive, free and open knowledge needs trust to thrive. Trust comes from the possibility always opened to take what was built together and continue somewhere else, to explore new avenues or if the choices made here start to diverge from what the community expects. That's why Inventaire's code is a Free/Open software published under the AGPL3 licence. Today, the Inventaire experiment has a centralized technical architecture as decentralized architectures are hard to achieve: efforts are focused on bringing users value from open knowledge with as little pain as possible, but finding ways to overcome this centralization is part of the trip.

  • You own your data

    For advanced users, you can already download your inventory data at any time. In the future, data should be interoperable and synchronizable with Personal Data Stores. In the current architecture, the user has to entrust Inventaire with all her data: those private data won't be shared with any third party
