+`core-meta` provides a method of constructing a self-organizing database.
+It is useful to collate element meta-data for things like catalogs and for 
+designer.
+
+Example, an element folder has a `metadata.html` file in it, that contains a 
+`core-meta`, something like this:
+
+    <core-meta id="my-element" label="My Element">
+      <property name="color" value="blue"></property>
+    </core-meta>
+
+An application can import as many of these files as it wants, and then use 
+`core-meta` again to access the collected data.
+
+    <script>
+      var meta = document.createElement('core-meta');
+      console.log(meta.list); // dump a list of all meta-data elements that have been created
+    </script>
+
+Use `byId(id)` to retrive a specific core-meta.
+
+    <script>
+      var meta = document.createElement('core-meta');
+      console.log(meta.byId('my-element'));
+    </script>
+
+By default all meta-data are stored in a single databse.  If your meta-data 
+have different types and want them to be stored separately, use `type` to 
+differentiate them.
+
+Example:
+
+    <core-meta id="x-foo" type="xElt"></core-meta>
+    <core-meta id="x-bar" type="xElt"></core-meta>
+    <core-meta id="y-bar" type="yElt"></core-meta>
+
+    <script>
+      var meta = document.createElement('core-meta');
+      meta.type = 'xElt';
+      console.log(meta.list);
+    </script>
