Abstract
    The initial release of OBIS, the Ocean Biogeographic Information System, provided a distributed search mechanism to retrieve marine species distribution records from a range of remote data providers in real time, based on a match on species scientific name and other parameters if specified. This ‘fully distributed’ version 1 of OBIS was upgraded in 2004 to provide improved functionality, system response times, and metadata-level information on available data via the OBIS system, by the introduction of two new components, an ‘OBIS Index’ comprising a species name index and a spatial index, and a local cache of commonly queried attributes of OBIS data items, refreshed on a rolling basis from the remote data providers. The conceptual, implementation and performance aspects of these developments are described in the present paper.
