Abstract: A method and data repository for the delivery, storage, maintenance and controlled access to test data, stored in a centrally administered data repository. The system allows entities to store individual collections of data which may be public or private in keeping with their business needs, while permitting them to have or obtain access to other data within the repository in which they might have an interest. Reflecting the natural flow of information, the system uses a data storage schema that permits the storage of a virtually unlimited variety of test results in a series of compact structures. To do so, the schema utilizes a series of metadata structures that describe collections of instance specific information.

Abstract: Traceable material property data is maintained in a database and provided to users upon demand. Cohesive and logical definitions of material property datasets are provided that capture the different industry standard facets of a material property. Traceability information includes the manufacturer of the material, the source of the material, the property measuring authority, points of responsibility, facets and constraints of the measurement process. Attributes for dataset ownership and dataset access cost are maintained and only the dataset owner is allowed to update those attributes. The ability to control access to the dataset is provided to the data owner. A dataset's measuring authority is permitted to review and re-grade data. The ability to define groups of users is provided with a designated user having the ability to control group membership and set the group's policies with respect to access of datasets owned by any member of the group.
