 Description  « Hide
While there is no native "map" construct in JSON documents, we can simulate it by storing a map as an array of entries, with each entry having a "key" and "value" field with those being nested (if persistable), or just the value (if non-persistable). This then (potentially) provides us a way to query maps

SVN trunk now adds an array of "entry" objects each with "key","value" fields and this provides the (nested) embedding mechanism
