European Space Astronomy Centre (ESAC) Villafranca del Castillo, MADRID (SPAIN) Aurélien Stébé DALToolKit Ingestor & Server September 2006, Moscow DALServer Java server application serving FITS metadata Takes as input : Standard “S*AP” data query string (SIAP, SSAP, SLAP, etc...) Standard “S*AP” metadata query string (FORMAT=METADATA) Config Files & FITS Files & Metadata Table Gives as output : VOTable v1.1 filled with FITS metadata FIELDS info from Config Files metadata Future : Create templates for all the other DAL protocols

European Space Astronomy Centre (ESAC) Villafranca del Castillo, MADRID (SPAIN) Aurélien Stébé DALToolKit Ingestor & Server September 2006, Moscow DALServer - extra Output format : VOTable v1.1 (more soon...) Support for Circle / Rectangular Region Search : POS and SIZE Support for intervals : 18/42 or /42 or 18/ Support for lists : IR, X-Ray, Visible Support for fixed values : Automatic Web Form generation : ”application/fits” AS Format
