+The DAS servlet itself is served directly from the source, it cannot be edited:
+{{{
+<servlet>
+        <servlet-name>DasServlet</servlet-name>
+        <servlet-class>uk.ac.ebi.mydas.controller.MydasServlet</servlet-class>
+</servlet>
+<servlet-mapping>
+        <servlet-name>DasServlet</servlet-name>
+        <url-pattern>/das/*</url-pattern>
+</servlet-mapping>
+}}}
+
+The servlet reads a file named 'MydasServerConfig.xml' located in the WebContent folder.
+
+Inside MydasServerConfig.xml, all needed properties are set. For example:
+
+* URL of the DAS server (ie. XGAP application running on some IP adress)
+* XSLT transformation services of the DAS output
+* Default stylesheet for data sources
+
+The important bits are in the datasources section. Here we define what data goes into the DAS service. In the example:
+
+* We point to a class file: <class>mydas.examples.EnsemblTestDataSource</class>
+* A coordinate system is entered, needed to map the data to other DAS sources
+* The capabilities are defined. We tell DAS what this datasource can provide.
+
+What we want is:
+
+Phase 1.
+
+* New datasource(s) that provide data from an XGAP database in the form of class file(s).
+* Proper configuration of this source in the config xml.
+* A working connection to a DAS client
+
+Phase 2.
+
+* A plugin to 'edit' the config xml. For example, adjust organism and coordinate system.
+* Smart datasource/config files that serve out the data they can provide, depending on what is in the database.
+* A client integrated in XGAP that uses our own data as a source
+* Expanding the client so it uses other sources as well, build a plugin around this to the user can quickly add/remove sources
+
+The last two can be done by eg. IFRAMing an existing client and entering our application URL to the list of sources, making use of existing software and source listings.
