NFTWATCH - an RDF based ontology to describe exhaustively what NFT are, as well as a set of IT tools to interact with it 

The NFT market is booming and is lacking both specialised data vendors and data models to analyse it. The information is spread online, onchain, in multiple marketplaces. NFTWATCH is an open-source project aiming to help the collect and aggregation of all NFT related information.


Motivation for the project:

We will provide a RDF based ontology describing NFT.
We will provide open-source tools to collect, enrich, store, and analyse NFT data coming from multiple offchain and onchain sources.

Generic use case description:

An artist wants to analyse the current NFT trends. What are the collections that sell the best, how to categorise them?
A NFT investor wants to make sure he is buying a legit NFT at the correct price. 

Essential functionalities:

NFTWATCH comes with a data pipeline system, able to collect, store, enrich and query any type of NFT information, organised around a RDF graph.

How these functionalities can be integrated within the software ecosystem:

Reusing the same ontology will enable the ecosystem to create their own data scrappers to feed the same database. Also, the data stored in NFT watch can easily be queried based on the open source and publish RDF graph. 

Gap being addressed:

Getting good quality data on the NFT market. 

Expected benefits achieved with the novel technology building blocks:

We’ll provide the framework enabling the ecosystem to easily collect NFT data and expose it – for whatever use -through API or possibly onchain based oracles.  

Potential demonstration scenario:

An online website initially fed from Opensea data enabling to query NFT data from new data criteria. Eg: show me NFT collections with horses and dogs, how many NFT with animals represented have been sold yesterday, and at what average price.
