Conclusions: We have successfully migrated the SEVCO/ HEvKA terminology development process to another domain and achieved a remarkable level of consensus. Feasibility and stability of the process have been demonstrated. That success will lead to coherence across GRADE reports and their computability allowing results of the GRADE process to be widely disseminated.

Background: GRADE is a de facto methodological framework and terminology standard for certainty-of-evidence and evidence-to-decision judgements. Computer applications such as GRADEpro and MAGICapp require crisp and well-defined terms. Formalizing the terminology of GRADE into a harmonized ontology will provide a technical infrastructure that will enhance the efficiency of creating and reusing GRADE data.

Objective: Develop and maintain a standardized, computable vocabulary of terms, an ontology, necessary for the expression of GRADE certainty-of-evidence and evidence-to-decision judgements.

Methods: Using a 13 step HEvKA/SEVCO term definition protocol (Alper et al), an international group of GRADE experts meet virtually each week in open meetings to curate terms from published GRADE guidances, establish preferred and alternative terms for included concepts, define the concepts, and write guidance for application.

Any dissenting comments or votes are discussed until agreement is reached. A globally agreed approach across a diverse community is required to create a comprehensive consensus.
