Includes all Graphic User Interfaces, whether hosted locally (on a user's desktop/browser) or remotely (on the web.) In the context of the JISC IE, presentation layer services interact with fusion and provision layer services via the following protocols and standards: Z39.50, SRW, the OAI-PMH and RSS/HTTP. Presentation layer services are sometimes synonymised with portals; portals, however, should be understood more narrowly, as discrete network services that provide a personalised, single point of access to a range of heterogeneous network services, local and remote. Thus, portals can be seen to be a type of presentation layer service; to synonymise portals with all possible human-computer interfaces can broaden the term beyond meaningful use. |
