All the data indexed by EASIN from distributed data sources e.g. used by the widget framework are made available via the interoperable web-services. The services were implemented respecting various open standards, i.e. freely available specifications and rules, such as OpenSearch, OGC, and TDWG.
Using open standards ensures interoperability among different software products made by different manufacturers. These principles mean that users can implement custom solutions without having any knowledge of the service providers. This facilitates just-in-time integration and allows users to implement new ideas easily and dynamically.
Most of the EASIN web services use the RESTful approach and return requested data as XML. The mapping service is built upon OGC WMS 1.3.0 standard, which allows easy integration into users’ mapping applications. In addition, each map layer is accompanied with INSPIRE compliant metadata.
