<p>Metacat is a flexible metadata database. It utilizes
|
|
36
|
<a href="http://www.w3.org/TR/REC-xml" target="offline">XML</a> as a
|
|
37
|
common syntax for representing the large number of metadata content
|
|
38
|
standards that are relevant to ecology. Thus, Metacat is a generic XML
|
|
39
|
database that allows storage, query, and retrieval of arbitrary XML
|
|
40
|
documents without prior knowledge of the XML schema. For a user level
|
|
41
|
overview of Metacat, please visit the
|
|
42
|
<a href="../user/metacattour.html">Metacat Tour</a> documentation.
|
|
43
|
</p>
|
|
44
|
<p>
|
|
45
|
The Metacat database models XML documents as a DOM tree, basically
|
|
46
|
decomposing the nodes of the XML document and storing the node data
|
|
47
|
as a series of records in a relational database via a JDBC connection.
|
|
48
|
At this point, only Oracle and PostgreSQL have been tested as a back end databases,
|
|
49
|
but we have avoided RDBMS specific features in order to maintain portability
|
|
50
|
to other relational databases.
