English preferred label fusion layer services New-Proposed
English note The positioning of some services within the fusion layer might be seen to be ambiguous, as it is possible for that activity defined as ""fusion"" activity to be undertaken directly by services more readily identified as belonging in either the provision or presentation layers. To take an example, commercial abstracting and indexing services, such as ISI Web of Science, are hard to place within the JISC IE architecture. While they might be thought an ""index"", based in part on the generic name of the type of service that they offer, their interfaces are made directly available to the user, and as such might be thought to be a ""portal"", thus placing them in the presentation layer. In other cases, stand-alone fusion services may be developed. In the case of cross-searching, such stand-alone services are typically referred to as brokers. In the case of harvesting and alerting, such services are referred to as aggregators. Services in the fusion layer may combine the harvesting and distributed searching approaches. For example, a fusion service may gather metadata records from content providers using the OAI-PMH, and make the combined database of gathered records available for searching using Z39.50. Published
