LPG started in 2006 to develop the GhoSST service (formerly called STSP) [ghosst.obs.ujf-grenoble.fr] that will comprise a set of spectroscopic and physical data bases on several types of solids (atomic and molecular, complex organics, minerals). The current development is focused on the spectroscopic database (spectra and band list) of molecular solids, its associated administration and query interfaces and some related spectroscopic tools. A prototype for band list data will be delivered end of 2008. A preliminary data model covering this field has been developed and will constitute a starting point for the development of a more general data model of physical data on atomic and molecular solids.
