This presentation at EnviroInfo 2008 in Germany discusses SEIS's challenges and the technical approach of ORCHESTRA in creating a shared information space. SEIS aims to streamline data collection and management, improve accessibility, and reduce administrative burdens in environmental policy. ORCHESTRA's ambition is to develop a service-oriented architecture for risk management in Europe, ensuring data accessibility, interoperability, and common terminology. The presentation explores conceptual and implementation architecture, major services/interfaces, and meta-information for establishing interoperability through cataloging and querying resources efficiently.

Overview • SEIS’s challenging tasks and requirements • Technical Approach to a shared information space (Re-use ORCHESTRA) • Benefits • Conclusion
SEIS’s challenging tasks and requirements • Collect data once; Use and share them many times. • Modernisation and simplification of the collection, exchange and use of data and information for the design and implementation of environmental policy • Manage the data at their source level. • Replacement of centralised systems for reporting by systems based on access, sharing and interoperability • Provide accessibility and availability of data (to public authorities) at any time and at all levels, from local to European, to facilitate reporting obligations as well as to inform citizens about the state of the environment. • Improve the quality and availably of information required for environmental policy • Keep administrative burdens to a minimum • Make information available in relevant national languages • Re-use investments (at regional, national, EU) Source: SEC 2008

ORCHESTRA in a nutshell • ORCHESTRA objectives • To design and implement an open service-oriented architecture (SOA) (e.g. for risk management) in Europe • To develop a set of services that are useful for various environmental (e.g. risk management) applications • To validate the results (i.e. architecture and services) in multi-risk scenarios (pilots) • To improve accessibility and availability of data (e.g.: cross-border) • To enable interoperability between systems by a standards-based IT architecture • To overcome the lack of a common risk management terminology, the diversity of procedures, policies and business models (with the use of semantics).

Meta-information – establishing Interoperability • Service capabilities • Service capabilities comprise a set of meta-information of a service which can be delivered to a service user as a self-description of the service. • They can be specified by means of an ORCHESTRA Application Schema for Meta-Information (OAS-MI), which can be published in a catalogue and used by clients to discover a service. • Furthermore, it contains all necessary information enabling a client to invoke operations provided by a service.
ORCHESTRA catalogue service • Ability to publish, query and retrieve descriptive information (meta-information) for resources (i.e. data and services) of any type. Specific characteristics are described in (Hilbring and Usländer, 2006), such as: • not tied to a particular schema of a meta-information standard (e.g. ISO 19115) • supports application schemas for meta-information designed according to the ORCHESTRA rules • may be used as a data catalogue or a service registry • may be cascaded with OGC catalogues or OASIS UDDI • includes an adapter to Internet search engines (e.g. Yahoo) • includes an extension for ontology-based query expansion and result ranking

Benefits • End users • Flexible and semantically enhanced search of information • Access to all available information • Same understanding (through defined glossaries and ontologies) • Software Developers • It provides a uniform conceptual model of both the information and the service viewpoint and • Tackles the problem of both syntactic and semantic interoperability. • It is specified both on a platform-neutral level and on a platform-specific level. • Investors • Exploit existing investment and experience for your application; enable re-use for other applications • Accelerate developments; reduce development and maintenance costs
Conclusion • SEIS tries to solve numerous problems on various administrative levels in the European Union by defining a new infrastructure with the goal of reducing the number of copies of the same information to a minimum for improved manageability, and maximizing its sharing and accessibility throughout the public authorities and the citizens. • ORCHESTRA worked successfully for about three years to develop a service oriented architecture (including the specification and implementation of services) for an infrastructure as well as to provide a reference model for interoperability and accessibility of data and services cross boundaries. • Certainly ORCHESTRA does not provide an out-of-the-box solution for all SEIS problems and requirements but it can easily be adapted. • It is also noteworthy that the ORCHESTRA architecture is open, which means that every institution and organization can adopt it free of charge. • Most of the services will be licensed under open source. • Thus, “SEIS ready” seems to be a good attribute for ORCHESTRA!
