Introduction
Data-intensive sciences lives from data. More and more interdisciplinary projects are aligned to mutually gain
access to their data, models and results. In order to achieving this, an umbrella project GLUES is established in
the context of the “Sustainable Land Management” (LAMA) initiative funded by the German Federal Ministry of
Education and Research. The GLUES (Global Assessment of Land Use Dynamics, Greenhouse Gas Emissions and
Ecosystem Services) project supports several different regional projects of the LAMA initiative: Within the
framework of GLUES a scientific Geodata Infrastructure is implemented to facilitate publishing, sharing and
maintenance of distributed global and regional scientific data sets as well as model results. The GLUES GDI [1]
supports several OGC webservices like the Catalog Service Web (CSW) which enables it to harvest data from
varying regional projects.

The Project SuMaRiO
One of these regional projects (RPs) is the SuMaRiO (Sustainable Management of River Oases along the Tarim
River) project. SuMaRiO aims to support oasis management along the Tarim River (PR China) under conditions
of climatic and societal changes. SuMaRiO itself is an interdisciplinary and spatially distributed project. Working
groups from 12 German institutes and universities are collecting data and driving their research in disciplines
like Hydrology, Remote Sensing, and Agricultural Sciences among others. Each working group is thereby
dependent on the results of another working group.
This circumstance makes it necessary to establish an infrastructure for scientific data which enable distributing,
sharing, and publishing of data and metadata. Further, this infrastructure for internal uses of SuMaRiO
scientists can be simultaneously enlarged and connected to the GLUES GDI.
General Design
The data infrastructure should bridge the spatial
distribution of participating institutes as mentioned
before and provide interfaces for other services to
harvest the information like the GLUES GDI. For that
purpose we could use the well-established eSciDoc [2]
infrastructure at the German Research Centre for
Geosciences (GFZ). Within eSciDoc a metadata based
data-exchange platform panMetaDocs [3] can be used
by SuMaRiO participants collaborative. The tool
panMetaDocs supports an OAI-PMH [4] interface which
enables an Open Source metadata portal like
GeoNetwork [5] to harvest the information. This enables
the GLUES CSW further to harvest the SuMaRiO data via
ISO 19115 interface from the GeoNetwork CSW and
pass this to the users. However the data download is
protected by a password access.
Further, the data added in panMetaDocs can be labeled
with a DOI (Digital Object Identifier) [6] for publishing
the data subsequently. A WebGIS allows additionally
access to spatial data via WMS or WFS interface. See
figure 1 for all of this described explanations.
Outlook
These components of spatially distributed data repositories, CSW interfaces,
and a WebGIS application complete a preliminary Scientific Spatial Data
Infrastructure (SSDI) [7] for SuMaRiO. It is now increasingly important that as
many scientists project-sided use this infrastructure and populate it with data
and metadata. The next stage of the SSDI is the roll-out of that infrastructure
as data provider for supporting a Decision Support System (DSS) for SuMaRiO.
SuMaRiOs metadata can be requested via the GLUES Catalog website,
searching for sumario.
