The sub-fields continuum and mesoscopic modeling, which constitute a substantial portion of the materials modeling domain, describe the behavior of various materials as a function of material properties/parameter and environmental conditions;  Scientists who wish  to describe an observed behavior, face the task of matching an observation with the best-fitting model. Due to the myriad and constantly growing number of available models in the literature and the scientific community, this task becomes increasingly more challenging to tackle efficiently. The MarketPlace platform can help in the discovering process. An important functionality of the platform is to provide knowledge about various topics in the field of materials modeling for various stakeholders such as manufacturers and translators. Among others, it employs a material modeling ontology for classifying  material models and relate it to experimental observations. This ontology consists of three parts: (1) a hierarchic structure of models based on common literature and expert interviews; (2) the observed behavior of the material in the experiment and additional properties that defines the validity of a model for specific conditions, and (3) the model equations themselves, where each equation has a left-hand side and a right-hand side that contain the variables and common constant values required to solve the equation. Based on these three parts of the model description, the user is able to find the best fitting model by composing a corresponding query. Additionally, the MarketPlace will enable community members to contribute to the growing knowledge base.
