Description

Using this extension point plug-in can provide data elements exporters in different formats.

Format combo box in Data element export dialog shows all formats suitable for selected element.

List of suitable formats depends from data element type, for example semantic network diagram can not be exported in SBML format. DataElementExporterRegistry is used to select suitable formats for the specified diagram type.
