@@ -87,6 +87,29 @@
  * reworking of the metamodel handling in OJB and XDoclet
    * merging of the two metamodels
    * new helper class that allows easy creation of the metamodel at runtime from classes
(via reflection 'magic')
+   * definition of Java 1.5 annotations for OJB (similar to the javadoc tags)
+
+ * enhancement of connection/model configuration
+   * introduction of !PersistenceConfiguration (PC) that combines one JCD with one Model
(descriptors) and defines additional mappings:
+     * concrete sequence-managers to sequence-names used in the descriptors
+     * concrete object-cache's to aliases used in the class descriptors
+   * allow definition of multiple sequence managers in one JCD
+   * easier runtime definition of JCD's and models
+   * ability to use multiple PCs in the same VM
+
+   ''[tomdz] This allows to truly separate model from connection description and to configure
them together as needed''
+
+ * OJB configuration enhancements
+   * should be doable completely at runtime (fully dynamic)
+   * use of fully qualified property names that reflect bean properties of the configured
component, e.g. org.apache.ojb.odmg.locking.!LockManager.maxLocks
+   * implementations are chosen via a *.class property, e.g. org.apache.ojb.odmg.locking.!LockManager.class
+   * the default values should be specified in the components, not in OJB.properties (->
usage of OJB without any external files)
+
+ * ability to specify the used persistent field class per class descriptor/field descriptor
+
+ * optional inheritance (controlled via a flag in the class descriptor) of feature descriptors
between class descriptors which makes copying feature descriptors from super classes no longer
necessary
+
+ * deprecation of 'extent-class' in favour of an extends attribute for the sub-class descriptor
(i.e. more like Java, but without the separation into Class/Interface)
