| A stepwise integration of existing expertise, distributed information
resources and services of the modeling community is inevitable. A
growing user community calls for consistent access to existing resources
like model documentation, (post-)processing tools as well as climate
model data.
Whereas substantial effort is invested to establish world wide climate
model data handling infrastructures (e.g. the CMIP5/ESG data
federation), e-infrastructural support to integrate information from the
existing modeling groups, data centers as well as computing centers is
missing.
From a technical viewpoint, in this talk we discuss the selection and
development of e-infrastructural components for the European IS-ENES
project. These components should facilitate consistent access to the
european CMIP5/AR5 data and service providers in addition to providing a
consistent view to diverse information and tools provided by the
european modeling community.
The components discussed include: portal technology, information
exchange protocols to collect highly structured as well as less
structured descriptions (metadata) in the portal, semantic web
technology to support searching based on a conceptual model.
A prototype of a semantic search interface for the IS-ENES portal is
hereby described in more detail. It is based on a first conceptual model
taking into account the information model developed in the Metafor FP7
project as well as specific IS-ENES needs. Metafor will provide the
metadata foundation of the future CMIP5 data federation and thus
provides a highly structured conceptual model for the model and model
output related part of the IS-ENES infrastructure. This has to be
related to less structured information sources describing associated
dokumentation, tools, expertise, etc. in the community. |
