A demand for openness imposes usage of interfaces and exchange of data by commonly accepted
standards. This requirement is satisfied using OGC standards (WMS and WFS) for Web services
interfaces and data interchange. Although Ginis framework offers full support for the Web-enabled
GIS, third parity OGC conformant Web Map and Web Feature servers can be successfully linked to a
WebGIS portal. For further extending of the portal functionality beyond mapping and querying,
extending of this set of standard services should be considered.
