HOLY: An Ontology covering the Hydrogen Market

This repository contains the current version of the Hydrogen Ontology and all the resources generated througout its development. It's the code corresponding to the paper "HOLY: An Ontology covering the Hydrogen Market"

The Hydrogen Ontology (HOLY), a domain ontology modeling the complex and dynamic structures of hydrogen-based markets. The hydrogen economy has become a politically and economically key sector for the transition to renewable energy, accelerating technological and socio-economic innovations. However, attainment of market insights requires a large variety of informational concepts which are predominantly found in unstructured text data. HOLY provides the necessary structure for the representation of these concepts. Through a top-down approach, HOLY defines taxonomies based on a hierarchical structure of products and applications. In addition, to ensure reusability, the ontology incorporates components from established ontologies in its structure. As a result, HOLY consists of over 100 classes storing information about organizations, projects, components, products, applications, markets, and indicators.
