Principles of ontology development after Wright et al ²⁴ and actions taken in the ENABLE project

Principles	How they have been applied in the ENABLE project
Have specified scope and scientifically sound and relevant content	Selection of established definitions for delimiting the scope, consultation of stakeholders, piloting for data input and platform search.
Meet the needs of community of users	Consultation of stakeholders, steering committee and Action members sampled from the user community and including diverse areas of expertise.
Enabling users to understand the meaning of entities	Naming examples of existing ontologies, piloting Delphi survey, technology description form, user form and platform use.
Be logically consistent	Using the methodology recommended for attribute description, checking consistency via Ontology Web Language.
Be interoperable with existing ontologies	Adopting attributes and labels available in existing ontologies and classifications, expert input on additional attributes and recommendations for interoperability.
Reflect changes in scientific consensus and remain accurate over time	Repository in open access, sustainability plan developed with Action members and stakeholders.
