 == Overview ==
 
+This RFC updates !MapGuide to use the latest version of Berkeley DB XML.
+
+For details, refer to Berkeley DB XML 2.3 release notes: 
+
+ http://www.oracle.com/technology/documentation/berkeley-db/xml/relnotes.html
 
 == Motivation ==
 
+There was some report from the user group that the !MapGuide repository got corrupted (though recoverable). The Berkeley DB XML 2.3 upgrade could help minimize such incident.
+
+The benefits of Berkeley DB XML 2.3 release include: 
+
+ * General bug fixes.
+ * Conformance to W3C recommendations for XQuery 1.0 and XPath 2.0.
+ * Performance and scalability improvements.
 
 == Proposed Solution ==
 
+Modifications need to be made to the !MapGuide server and its installer:
+
+ * The server will detect a version mismatch at startup and throw an exception, prompting the user to upgrade.
+ * The installer will back up the existing repositories, then run the upgrade script.
+ * The installer will need to install the upgrade script so that it can be run independently.
 
 == Implications ==
 
+There is no way to revert the upgrade, so the repositories must be backed up.
+
+Users must read documentation on repository upgrade before performing an upgrade, or there is risk of data loss.
 
 == Test Plan ==
 
+Tests need to be done after the upgrade:
+
+ * Resource Service unit tests must all pass.
+ * Scripts that back up, restore, and recover repositories must run successfully.
 
 == Funding/Resources ==
