The wealth of seismic data available from space borne missions (SOHO, CoRoT, Kepler, SDO,…), and from ground-based observations (GONG, Bison, ground-based large programmes…), is stimulating solar and stellar structure and evolution studies but is also opening new scientific perspectives (e.g. characterization of planetary systems, stellar population in our galaxy, etc…). These applications address a broad scientific community within and beyond the solar and stellar communities. They require combining data of various types and from various sources. The Seismic Plus Portal intends to help this increasing use of seismic information by providing, at a well-identified place, a homogeneous description and access for sources of solar and stellar seismic data as well as for sources of complementary and ground-based data. The Seismic Plus portal is now open and available at http://voparis­spaceinn.obspm.fr/seismic­plus/. It is currently being developed in the framework of the SPACEInn project (Exploitation of Space Data for Innovative Helio- and Asteroseismology) financed by the European Union under the Seventh Framework Programme (FP7). We describe here the opening of the Seismic Plus portal and provide a short description of its main functionalities.
