+<section><title>Introduction</title> <p>The File Converter Framework provides
+the following: </p> <ul>
+<li id="GUID-75C46CFD-2B82-5500-AADA-E9E86CE8E894"><p>An abstract interface
+which all converters must implement. </p> </li>
+<li id="GUID-657490ED-CACA-5C43-BE75-5FBB954F2625"><p>APIs to list and search
+for converters. </p> </li>
+<li id="GUID-97761F64-2821-5845-86AD-1912B6E551F8"><p>APIs to determine the
+MIME types supported by the available converters. </p> </li>
+<li id="GUID-4D4812BA-9B84-5022-81B5-784F80FF5C75"><p>An observer interface
+through which the progress and success or failure of the conversion can be
+reported. </p> </li>
+</ul> <p>Converters are implemented as <xref href="GUID-9E92EE30-F2E2-5F28-BB2A-391C09EC69D2.dita">ECom
+plug-ins</xref>, each of which can implement one or more converters. Like
+all binaries, the plug-ins are installed in the <filepath>\sys\bin\</filepath> directory.
+Each plug-in must provide two resource files: one contains a <codeph>CONARC_RESOURCE_FILE</codeph> resource
+to describe the converters implemented in the DLL, and the other is a registration
+resource file required by the ECom framework. </p> <p>The following UML diagram
+shows the key elements of the converter architecture, including an example
+client and an example converter DLL that provides two converters, <codeph>myConverter1</codeph> and <codeph>myConverter2</codeph>. </p> <fig id="GUID-6E58825A-CBE2-52B8-B7BD-6D263A0751F4">
