Seven Slides to a Provocative CyberInfrastructure John Rumble Information International Associates Oak Ridge TN CyberInfrastructure in Materials Science My Credentials CyberInfrastructure in Materials Science Standards • Why • For What • How CyberInfrastructure in Materials Science Standards - Why • To help materials R&D exploit the Information Revolution • The NSF CyberInfrastructure wants ideas! CyberInfrastructure in Materials Science Standards – For What The Basics • Material Uniqueness – that specific material Equivalency – two materials are the same to a specified degree • Properties and characteristics • Conditions under which that property and characteristic is valid CyberInfrastructure in Materials Science Standards – For What Interoperability of • Databases • Software • Data exploitation (visualization, mining and more) • Articles and automated experiment/calculation reporting and deposition • Archiving • More CyberInfrastructure in Materials Science Standards - How • Neutral formats Allows one to maintain own format Only requires translation into and out of format • Define data elements Include normal data dictionary (ontology) information Identify minimum set necessary Define others in case wanted or needed Allow extensions (self-definition) Do not underestimate difficulties in resolving nomenclature problems • Separate semantics from syntax CyberInfrastructure in Materials Science Standards - How • You must be motivated to build a standard • You must have motivation to use a standard • Industry builds and uses standards for business reasons • If it is hard to build a standard, the motivation is usually lacking • Why do scientists build standards? CyberInfrastructure in Materials Science The Opportunities for NSF CyberInfrastructure and Materials Science 1. R&D on the use of MatML in data exploitation – visualization, mining, etc. 2. R&D on metadata requirements and use of MatML in software interoperability – up/down material scale; software components 3. R&D on the theory of measurement uncertainty for modeling and simulation: physical models; algorithm development; coding [perhaps with NIST] 4. R&D on standards for materials data/information archiving: who, what, how, support, deposition, compatibility, international issues [perhaps with CODATA] CyberInfrastructure in Materials Science CyberInfrastructure is in Its Infancy Newgrange – Ireland • • • • 6000 years old Aligned to the rising sun in the winter solstice Depended on careful observational data on the rising sun One data point!
