<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 |
4522
|
daigle
|
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.

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.

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 |
4080
|
daigle
|
to other relational databases.
