A Distributed Metadata Management, Data Discovery and Access System
Mercury is a federated metadata harvesting, search and retrieval tool based on both open source and software developed at Oak Ridge National Laboratory. It was originally developed for NASA, and the Mercury development consortium now includes funding from NASA, USGS, and DOE. A major new version of Mercury was developed during 2007. This new version provides orders of magnitude improvements in ...
متن کاملData and Metadata Management
In this chapter we illustrate fundamental notions of Data Management. We start from the basic concepts of database schema and instance, illustrating how they are handled within dictionaries in relational databases. We then address, from a general point of view, the notion of data model as a means for the representation of information at different levels of details, and show how dictionaries can...
متن کاملSystem for Eeg/erp Data and Metadata Storage and Management
The purpose of this paper is to introduce a system for EEG/ERP (electroencephalography, event-related potentials) data and metadata storage and processing and to summarize the authors’ research in this field. Since researchers have difficulties with a suitable long-term storage and management of electrophysiology data the presented system helps them to increase both efficiency and effectiveness...
متن کاملMetadata Management System (MMS)
Much have been said about metadata which is “data about data” used for classification and retrieval of information. However, metadata is not created by itself. This paper will present the design, interface and implementation of our own metadata tool called Metadata Management System, MMS that was developed to facilitate the creation, maintenance and storage of metadata. This metadata tool suppo...
متن کاملTwo-Level Metadata Management for Data Deduplication System
Data deduplication is an essential solution to reduce storage space requirement. Especially chunking based data deduplication is very effective for backup workloads which tend to be files that evolve slowly, mainly through small changes and additions. In this paper, we introduce a novel data deduplication scheme which can be efficiently used with low bandwidth network in a rapid time. The key p...
