Symposium

3. EnvEurope project
• Proposes a design for environmental high
quality monitoring and long-term research
sites
• Exemplary establishment of common
parameter sets to be collected across LTER
Europe network
• Based on existing infrastructures = lot of
valuable date series
• Focuses on 3 types of ecosystems
(terrestrial, marine and freshwater)

Symposium

4. EnvEurope project
• Aims to select&collect data from E-LTER to
provide information on environmental
quality in respect of indicators and
methodologies applied in main European
networks (E-ELTER, EIONET, Natura2000, etc.
• Reorganise E-LTER network on the basis of
suitable sites, reflecting ecological, political,
economic stratification of Europe = will
contribute to SEIS and GMES

5. EnvEurope project – use cases
• 2 user groups
• Exchange data
• Services
• Metadata

BAD SCHANDAU (SAX) # DECIN (CZE) 23-24/5/2011
Symposium

6. Metadata in EnvEurope
• Metadata levels
– Site level metadata - LTER InfoBase
metadata online entry point
– Dataset level metadata – no centralized
metadata management tool, no online
discoverable metadata
– Both levels are important for users
GI2011-X-BORDER-SDI/GDI
BAD SCHANDAU (SAX) # DECIN (CZE) 23-24/5/2011
Symposium

7. Dataset level metadata
• EnvEurope MD specification development
– Reference MD specification – EML
– Extent definition - which element for what
purposes (discovery, evaluation,
use)?&What is required by INSPIRE
legislation?
– Documentation – UML, element details,
XML examples
– Implementation – MD management tool
• Metadata acquisition and USE

8. EnvEurope MD specification
Conceptual model – UML class diagrams derived
from XML schemas

9. EnvEurope MD specification
MD elements description tables
Metadata element name Dataset title
Definition Provides a name of the dataset that is being documented as is
known within community.

Multiplicity 1
INSPIRE/ISO element 1.1 Resource title/360. Title
Example •Density and Biomass of phytoplankton in Lake Candia (1986)
Example EML XML encoding <title>Density and Biomass of phytoplankton in Lake Candia

• Totally 20 MD elements defined and described
in this way

20. Conclusions&Future work
• Developed MD specification should
satisfy both EnvEurope users&INSPIRE
• Partial efforts to bring EML2ISO has
been realized
• Further mapping has to be done
• EnvEurope MD management system
has to be implemented
• We have to get dirty with MD and
collect them
