Mersea
project deals with numerous activities,
like sea observations, scientific researches, data assimilation in
numerical models, information management, public information… These
activities are done by providers (, scientific teams, data
centers, modelisation centers, …) which work part of time for
Mersea.
Mersea
providers are classified in two main thematics :
-
observation data providers. Data providers are
observation systems such as ARGO data management system, CLS, Coriolis,
… Managed observation data are in-situ; forcing fields and remote
sensing measurement
-
model providers Models providers are assimilation models such as
Mercator, MFS, FOAM, TOPAZ. Models are both global and regional
Due to the amount of
providers involved in Mersea project, an Information Management System
is necessary for exchanges within the project and relationship with
users. A portal will be the main entry point for users interested
by Mersea results. For more (click)
General context Overview
In order to federate Mersea
services, and considering the fact that services classified in the same
thematic share close operational rules, Mersea services have been
assembled by Thematic Portals (TEP’s).
A
TEP is a logical system entity responsible for
providing services, aggregated on a thematic basis, to other TEP’s,
general services (Mersea Information Management) or users. In general,
a TEP has no physical implementation and consists of a collection
of services distributed among providers physical systems. However, it
is under TEP responsibility to define, describe and insure that
necessary services are implemented.
In
other words, TEP’s are delegation mechanisms to thematic
communities to organize the Mersea services they have to operate. Doing
so, TEP’s are in charge of :
-
federating services embedded in TEP, checking
those services are consistent and not redundant,
-
describing services and products,
-
operating services in a common way.
-
monitoring services and reporting at Mersea
level.
Eight
