The Materials Innovation Network is a collaborative environment built to fuel the Materials Genome Initiative by managing users and their digital data for microstructure driven materials development and improvement. SOCIAL NETWORK Manages users, projects, and expert communities engaged in materials science related efforts. A melting pot for materials scientists, big data, and integration. CODE REPOSITORY A platform with an embedded versioning system to develop codes and deployable tools for the MATIN community at large. This platform will enable good coding practices and rapid delivery of academic utilities to market quickly. DATABASE The database is the unifying feature of MATIN. This graph database is specifically designed to store nearly all types of materials datasets, maintain data provenance, semantically query metadata, learn design patterns ( or workflows ), support the big data generation, and establish a federated database with access control for academia, industry, and national labs.

TS Microstructure Informatics is a data-
driven system to mine structure-property/processing connections from experimental and simulation materials science information. The system is agnostic to material system and length scale, objectively quantifiable, and rapidly iterates in less cycles for both materials improvement and discovery.

DATA MINING MODULES
Microstructure Material Processing Property
Mining modules are machine Learning solutions to extract rich bi-directional structure-property/processing linkages from materials & microstructure datasets. Mining modules create structure taxonomies, homogenization and localization relationships, ground truth comparison between simulation and experiment, materials discovery, and materials improvement.
