One unified environment for a large community of users

One common grid for most legacy systems ( EMBOSS suite, BLAST …)

General and specialised DBs accessible through the federation

DB mirrors when needed

Duplication of services when needed

The Grid is much more than the “sum” of resources. Beside the evident “plus” of giving access to a wide community of users to the most up-to-date databases and maintained legacy systems

It offers new brand possibilities as joining databases, adding new services (e.g. on top of legacy systems) and generating user interfaces from the meta data for old fashioned systems.

Resources are described by meta data stored in a distributed catalogue and are incarnated into

components that are distributed transparently among all the systems participating on the Grid, with

appropriate relocation and replication mechanisms to guarantee seamless access.

The Grid provides transparent distant access to data and services resulting in a new federated information system of LS resources. Legacy resources can be

easily wrapped into the new system allowing

monolithic LS systems to evolve into an accretive, distributed, federated environment. Moreover, it proposes functionalities such as audit, debug, accounting and security.

The Grid is organized in layers with the possibility to add user-defined upper layers like query processors, script interpreters and expert systems.
