&lt;br /&gt;
== General description ==&lt;br /&gt;
&lt;br /&gt;
ABCD stands for '''Access to Biological Collection Data''' and is an XML based format. It is a ratified TDWG (Biodiversity Information Standards, formerly Taxonomic Databases Working Group) standard and the current version is 2.06b (though 2.06 is most commonly used).&lt;br /&gt;
&lt;br /&gt;
The ABCD documentation can be found on the TDWG Wiki: http://wiki.tdwg.org/twiki/bin/view/ABCD/WebHome&lt;br /&gt;
&lt;br /&gt;
There are over 1400 different concepts that can be expressed in ABCD of which 1100 can contain data. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Extensions ==&lt;br /&gt;
ABCD allows for extension to the schema for special purposes that are not covered by ABCD. The two most notable extensions are ABCDDNA and ABCDEFG. &lt;br /&gt;
&lt;br /&gt;
=== ABCDDNA ===&lt;br /&gt;
ABCDDNA is the ABCD extension for DNA data and is also a ratified TDWG standard. It is maintained by the [http://wiki.bgbm.org/dnabankwiki/index.php/ABCDDNA DNA Bank Network]. &lt;br /&gt;
&lt;br /&gt;
=== ABCDEFG ===&lt;br /&gt;
ABCDEFG is the ABCD Extension For Geosciences and it is maintained by the [http://www.geocase.eu/efg GeoCASe Project]. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Software ==&lt;br /&gt;
&lt;br /&gt;
The ABCD format is used by biodiversity networks like [http://www.gbif.org/ GBIF] and [http://www.biocase.org BioCASe]. &lt;br /&gt;
&lt;br /&gt;
ABCD files can be created using the [http://www.biocase.org/products/provider_software/index.shtml BioCASe Provider Software] (it also works for the DNA and EFG extensions).&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Sample files ==&lt;br /&gt;
A sample document can be found in the documentation wiki for the BioCASe Provider Software: http://wiki.bgbm.org/bps/index.php/SampleABCDDocument&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Identification ==&lt;br /&gt;
&lt;br /&gt;
The XML namespace for ABCD 2.06 is &amp;lt;code&amp;gt;&amp;lt;nowiki&amp;gt;http://www.tdwg.org/schemas/abcd/2.06&amp;lt;/nowiki&amp;gt;&amp;lt;/code&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
The XML namespace for elements from the DNA extension is &amp;lt;code&amp;gt;&amp;lt;nowiki&amp;gt;http://www.dnabank-network.org/schemas/ABCDDNA&amp;lt;/nowiki&amp;gt;&amp;lt;/code&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
The XML namespace for elements from the EFG is &amp;lt;code&amp;gt;&amp;lt;nowiki&amp;gt;http://www.synthesys.info/ABCDEFG/1.0&amp;lt;/nowiki&amp;gt;&amp;lt;/code&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== References ==&lt;br /&gt;
&amp;lt;references/&amp;gt;&lt;br /&gt;
&amp;lt;!--List articles, books or web pages describing the format or supporting the evidence.--&amp;gt;&lt;br /&gt;
