The inventory is part of the Economy System, the first ready feature in the Ponifia System. It's been used for the water deliveries around the Tall Tails and other Ponifia's routes. The credits for building entire inworld setup goes to Vana Trouble and Mara Lucente.

The inventory allows you to keep resources that are RP-use and they don't have a non-RP value. Especially, we provide a fully RP currency: "Stirrup", that is not simply exchangeable to SL, then RL value. We wanted to avoid mindless farming and enhance roleplay and activity around Second Life.

Everyone can have one inventory attached to their account. It's where you collect things like stirrups, apples, water, work-tokens for doing the chores. Things around the economy backend needs to be implemented in world, it's why this feature will show its features in time.

For now the development is kept private but there is a plan to make an API available for developers.
