OVERVIEW OF NEES DATA AND METADATA MODELS

摘要

NEESgrid, the system integration of the NEES research collaboratory, uses recent advances inInformation Technologies for modeling the data sets and experimental processes generated at the NEEStesting sites. NEESgrid describes experimental results and processes using object-oriented data modelsexpressed in NEESML, the NEES Metadata Language, which is a subset of RDF (Resource DescriptorFramework). At the present, data models and data dictionaries are being developed for various fields ofearthquake engineering using Protégé-2.0, based on user surveys, usage scenarios and existing data sets.
