Data directory
This directory contains:



adb_export_sample.xml         
    A sample xml file with about 30 records.

adb_export_sample.json      
    A json file containing the sample data. It was created with:
    xml2json.pl  adb_export_sample.xml| jq '.'  > adb_export_sample.json
    This file serves as an example for how easily the xml format can
    be transformed into another format, via standard tools.

    Example of json format: https://www.astro.com/adbexport/adb_export_sample.json

xml2json.pl
    Perl program used for xml to json conversion.
    Other converters, like node-based xml2json can of course also be used.

c_sample.zip        
    A zip archive containing all data with names starting with C, not encrypted.
    A total of 5866 data records, of which 3692 have AA rating, revision version Feb 2026.
    Researchers should use these data to develop their tools
    and techniques, before requesting access to the full data set.
    For testing software processes which need reliable data this large data set is sufficient.

adbx_dma.xsl              
    A xsl script, which can extract birth data from the xml file into 
    a TAB separated text file. This file serves as an example to show
    how conveniently data from an xml file can be extracted for processing.
    It is used like this:
    xsltproc adbx_dma.xsl  adb_export_sample.xml
