Introduction
The White House’s Materials Genome Initiate (MGI) seeks to substantially improve the process of new material discovery and development, and shorten the time to deployment. Two of the core components of this initiative - new and sophisticated computer modeling technologies and next-generation experimental tools - received initial federal research support through 2012. The third major component is that of developing solutions for broader access to scientific data about materials to aid in achieving the goal of faster development of new materials at lower costs.
Our approach recognizes the need for providing easy access to large amounts of highly distributed and heterogeneous data – including unstructured (scientific literature or publications), semi-structured and structured data. We recognize the need to support a variety of data as well as resources that provide data using APIs and Web services. We recognize the need for tools to be able to easily exchange data. We also recognize the need for integrated provenance (i.e., data lineage) to support data quality and relevance, and access control for organizations to share information when desired and yet keep valuable intellectual property confidential. To address these requirements, we will use recent advances in semantic web (standards, search and query processing techniques and tools, Web of Data or Linked Open Data) and semantic services computing, along with integral support for provenance and access control. In a complementary effort during the first year, the development of domain models and knowledge bases (ontologies, taxonomies, and vocabularies), will be carried out with support from ARFL’s Materials and Manufacturing Directorate.
This three-year project will undertake three broad classes of tasks. The first related to creating semantic infrastructure including ability to create semantic metadata for a variety of data types utilizing domain models and knowledge bases. The second relates to semantic search for all varieties of data, including resources with services based access. The third relates to development of a novel semantic data exchange scheme for materials science (termed Linked Open Materials Data) by developing an open data based approach.
Approach
We identified that Semantic Mediawiki is the ideal tool for the task at hand. There are 11 Templates and 28 properties that we determined to be necessary for capturing the data in Material Science.
Data Model
In this section we discuss the details of the data model and vocabulary modelling. The following table describes the details of the templates

Properties
Property Template Approach
- This section discusses the details of the steps taken to automatically create the wiki pages for the entities in YAGO dataset
- Identify a list of regular properties
- Identify a list of Generic properties
- Create one page per property
- For each property check the count of datatypes it has (using group by query)
- if it has only datatype, map that dt to the wikidata dt (create the has type : type)
- else create an empty property
- if the object is URI then the datatype is Page
- Create a list of regular templates
- The name of the template is taken from the name of the property
- generate the regular template tag.
- Create a list of singleton templates
- The name of the template is taken from the generic property
- Add a UUID property for existing value of singleton property
- Generate the meta-template tag/code for each template
- For prperties created from yago, add another property to capture the data of the original property (make a link from this property to the original property to link to yago dataset)
- Virtuoso configuration.
- Analyze the statistics of the concept
