Semantic approaches to data integration are seen as an enabling mechanism to carry out integrated socio-

been developed building upon Umweltbundesamt’s (Federal Environment Agency – Austria) experiences in
developing a semantic database system for managing environmental data.
To validate the development of SERONTO and its uses for future data integration, a proof of concept study was
conducted.

List of parameters
Scope
The scope of the proof of concept was to test:
• The feasibility of mapping relational databases to SERONTO
• Querying of the connected database(s) from the semantic concepts captured in SERONTO
SERONTO
The requirements for accepting the proof of concept were: Results
• The databases must have different structures and must have been developed independently of SERONTO; Query
• The databases must feature reference lists (e.g. species lists);
• The database structures must not be altered as a result of the integration work;
• New concepts may be imported into SERONTO as and when required;
• The databases must contain data relevant to Long Term Ecological Research (e.g. vegetation surveys, records Results
of species occurrences, measurement of biotic and abiotic components). •We could import SERONTO and Units Ontologies into Ontostudio 100
•We could import Database Schemata into Ontostudio 50
•We could do simple and complex database queries 0
SERONTO
•We could readily extend SERONTO classes from the contents of databases Region 1 Region 2
•We could map databases to SERONTO graphically where relations between parameter method

•We could create more complex mappings including at instance level using the parameter_method

SERONTO allows to annotate WHAT is observed WHERE,
