Interoperability - Solar Resource Knowledge - Applications Schema

A problem of units ? of terminology ? Consult the Education service.

The SoDa Service contributes to the international efforts made towards the construction of the single and interoperable information space for a better share of knowledge on solar resource. Interoperability denotes the ability of systems to exchange information. The present SoDa Service is fully interoperable and offers unifieds and transparent access to many resources.

Interoperability and Standards
The interoperable technologies behind SoDa are being redesigned in order to obey standards. After a series of consultations with several bodies involved in standards, such as ISO, "GEOSS (Global Earth Observation System of Systems), INSPIRE (Infrastructure for Spatial Information in Europe) and national meteorological offices, a thesaurus has been defined which is specific to solar resource. A thesaurus is a set of terms that describe the solar resource. Together with the thesaurus, a series of tags is defined in the XML language for the practical implementation of this thesaurus: the Schema. A file is constructed that contained this series of tags and can be read by a computer; its extension is .xsd that stands for XML Schema Definition. A first version of the thesaurus was written in 2007 (Gschwind et al. 2007b)

This thesaurus will help in defining metadata. Metadata are essential to exchange knowledge between applications. They describe objects to be exchanged (e.g., a time series of irradiance, a geographical location, a date...).

Moreover, the SoDa Service contributes to the following initiatives:

• the Global Earth Observation System of Systems (GEOSS),
• the International Energy Agency (IEA, SHC Task 36),
• the project MESoR of the European Commission

The Soda Service hosts the application schema developed by the international community on solar resource knowledge. These schema helps to develop web services that are interoperable, i.e., that can be invoked by various portals. See publications.
