DOGMA-MESS achieves its overall objective of supporting collaborative communities in defining a relevant common ontology in an evolutionary process in which (core) domain experts and knowledge engineers interact intensively and in a focused way.
- In a preliminary stage, a "meta-ontology" is defined by the knowledge engineers, which captures the philosophical foundation of the ontology building process. This process only needs to be done once, and does not require involvement by the (core) domain experts
- Then the common ontology is produced in a "common meaning distillation" process, taking a number of iterations. Each iteration produces a validated version (see: Background - Ontology Versioning). The meaning distillation process consists of three stages:
- In the ontology elicitation stage, the participants articulate their definitions, making relevant tacit knowledge explicit, providing the raw material for the next layer of collaborative knowledge.
- In the semantic analysis stage, the quality of elicited definitions is improved and commonalities and differences in definitions are determined.
- The various individual and common definitions are compared in the meaning negotiation stage. The outcome of this process is a set of common definitions which provide either the final common ontology or the input for the next iteration.
