stands for the "A
ata". The world largest collection of raw 3D spectroscopic observations of galactic and
extragalactic sources observed with the Russian 6-m telescope of Special
is a prototype of an archive of
heterogeneous science ready
data, fed by ASPID
, where we try to exploit all the power of the IVOA Characterisation Data Model. Multi-level
Characterisation metadata is provided for every dataset. The archive provides powerful metadata query mechanism with access to
every data model element, vital for the efficient scientific usage of a complex informational system. We provide a set of
access interfaces: SIAP/SSAP, HTTP-based characterisation metadata query, Web-service accepting ADQL/x.
We use PostgreSQL DBMS for storing XML metadata, described by the IVOA Characterisation Data Model. System makes
heavy use of initial XML type support in the PostgreSQL in order to provide comprehensive search over
Characterisation metadata tree. This web interface implements HTTP-GET/POST based access and almost direct translation
of the query parameter name into XPath of the data model element in the XML serialisation.
More details of technical implementation and idea behind it are available in the ADASS-XVI posters:
