Adaptive Protocols for Information Dissemination in Wireless Sensor Networks

by Wendi Rabiner Heinzelman, Joanna Kulik, Hari Balakrishnan , 1999
"... In this paper, we present a family of adaptive protocols, called SPIN (Sensor Protocols for Information via Negotiation) , that eciently disseminates information among sensors in an energy-constrained wireless sensor network. Nodes running a SPIN communication protocol name their data using high-lev ..."

-level data descriptors, called meta-data. They use meta-data negotiations to eliminate the transmission of redundant data throughout the network. In addition, SPIN nodes can base their communication decisions both upon application-specic knowledge of the data and upon knowledge of the resources

The MetaCyc database of metabolic pathways and enzymes and the BioCyc collection of pathway/ genome databases

by Ron Caspi, Tomer Altman, Richard Billington, Kate Dreher, Hartmut Foerster, Carol A. Fulcher, Timothy A. Holl, Ingrid M. Keseler, Anamika Kothari, Aya Kubo, Markus Krummenacker, Mario Latendresse, Lukas A. Mueller, Quang Ong, Suzanne Paley, Pallavi Subhraveti, Daniel S. Weaver, Deepika Weerasinghe, Peifen Zhang, Peter D. Karp - Nucleic Acids Res , 2012
"... The MetaCyc database (MetaCyc.org) is a compre-hensive and freely accessible database describing metabolic pathways and enzymes from all domains of life. MetaCyc pathways are experimentally determined, mostly small-molecule metabolic pathways and are curated from the primary scien-tific literature. ..."

EDUTELLA: A P2P Networking Infrastructure Based on RDF

by Wolfgang Nejdl, Boris Wolf, Changtao Qu, Stefan Decker, Michael Sintek Ambjörn Naeve, Mikael Nilsson, Matthias Palmer, Tore Risch , 2001
"... Metadata for the World Wide Web is important, but metadata for Peer-to-Peer (P2P) networks is absolutely crucial. In this paper we discuss the open source project Edutella which builds upon metadata standards defined for the WWW and aims to provide an RDFbased metadata infrastructure for P2P applica ..."

The need for MetaData Standards

by Xam Sdk, Email Service
"... A type of data classification that indicates the bits are no longer changing Classifying this way enables storage systems to meet the requirements of this type of data Most data is created fixed Photos, videos, published/emailed documents, etc. 70-90 % of data becomes fixed at some point Even transa ..."

Ivy: A Read/Write Peer-to-Peer File System

by Athicha Muthitacharoen, Robert Morris, Thomer M. Gil, Benjie Chen , 2002
"... Ivy is a multi-user read/write peer-to-peer file system. Ivy has no centralized or dedicated components, and it provides useful integrity properties without requiring users to fully trust either the underlying peer-to-peer storage system or the other users of the file system. An Ivy file system con ..."

consists solely of a set of logs, one log per participant. Ivy stores its logs in the DHash distributed hash table. Each participant finds data by consulting all logs, but performs modifications by appending only to its own log. This arrangement allows Ivy to maintain meta-data consistency without locking

Provable Data Possession at Untrusted Stores

by Giuseppe Ateniese, Randal Burns, Reza Curtmola , Joseph Herring, Lea Kissner, Zachary Peterson, Dawn Song , 2007
"... We introduce a model for provable data possession (PDP) that allows a client that has stored data at an untrusted server to verify that the server possesses the original data without retrieving it. The model generates probabilistic proofs of possession by sampling random sets of blocks from the serv ..."

the server, which drastically reduces I/O costs. The client maintains a constant amount of metadata to verify the proof. The challenge/response protocol transmits a small, constant amount of data, which minimizes network communication. Thus, the PDP model for remote data checking supports large data sets

Biblio: automatic meta-data extraction

by Carl Staelin, Michael Elad, Darryl Greig, Oded Shmueli, Marie Vans, D. Greig, M. Elad, O. Shmueli - INTERNATIONAL JOURNAL DOCUMENT ANALYSIS AND RECOGNITION , 2006

P2P MetaData Search Layers

Modifying DHTs directly to support meta-data is difficult, and meta-data search systems such as flooding tend to scale poorly. However, a numb ..."
