DALIngestor: Client Tool for Spectra Ingestion Isa Barbarisi

2. DALToolKit: few steps to visualize your spectra
Why DALToolkit: we needed to create new SSAP servers for different sets of spectra and visualize them with VO-Clients (e.g VOSpec) in a simple and fast way
DALIngestor is a simple java applet which allows the ingestion of local spectra in a database following the directions of a Config File containing the SSAP parameters and the corresponding fits keywords. The fits headers are parsed to get the values of the SSAP parameters and if some keywords are not found the user has the possibility to insert them manually to mantain coherent the matrix of correspondences.
A fully compliant SSAP server is created around the database and it can be registered.In few minutes we had available two SSAP servers for XMM data (they can be seen with VOSpec)
In the future DALIngestor will be compatible with other VO standards (SIAP/SLAP..)

3. DALIngestor : Fits Files  Database
You have to provide: - your set of Fits Files - Config Files containing the list of the SSAP Parameters desired and the correspoding Fits Keyword

4. The Logic of DALIngestor
SSAP Server
DATABASE
FITS FILES
HEADER RA=10 DEC=41 TTYPE1=WAVE TTYPE3=FLUX …..
RA DEC X_AXIS …
WAVE
CONFIG FILE
Lots of different Fits Files!!
SSAP Parameters I want to extract from Fits Files are: RA DEC X_AXIS …
It’s configurable by the user

5. Config File Example <?xml version="1.0" encoding="UTF-8"?>
<RequiredParams>
<MetaColumn>
<ColumnName>Ra</ColumnName>
<ParamName>POS</ParamName>
<UTypeName>POS_EQ_RA_MAIN</UTypeName>
<FitsKeyword>RA_PNT</FitsKeyword>
<Description></Description>
<DataType>Double</DataType>
<ArraySize></ArraySize>
<Unit></Unit>
<UCD>POS_EQ_RA_MAIN</UCD>
<Values></Values>
</MetaColumn>
<ColumnName>SpectralAxis</ColumnName>
<ParamName>X_AXIS</ParamName>
<UTypeName>Dataset.SSA.SpectralAxis</UTypeName>
<FitsKeyword>TTYPE1</FitsKeyword>
<DataType>String</DataType>
<UCD></UCD> ….

6. Register and Open VOSpec
Once the SSAP Server is created it has to be registered so that VO-Clients (VOSpec..) can visualize it
