The goal of BioTorrents is to allow easier and faster exchange of science-related open-access software and datasets.
BioTorrents allows scientists to rapidly share their results, datasets, and software using the popular BitTorrent file sharing technology. (The BioTorrents website)
From Alain Borel (Bibliotheque Scientifique, Lausanne) on the CHMINF Listserv, 1/18/10, in response to the introduction of the subject by Egon Willighagen at Uppsala Univ.:
"The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is a low-barrier mechanism for repository interoperability. Data Providers are repositories that expose structured metadata via OAI-PMH. Service Providers then make OAI-PMH service requests to harvest that metadata. OAI-PMH is a set of six verbs or services that are invoked within HTTP."
