[basex-talk] Use with Google App Engine

I realize that BaseX can't be used as-is on the Google App Engine. The question I have is how much work would it be to get it up and running on the App Engine's datastore API instead of whatever you are using for indexing/storage. There is no access to a filesystem. The datastore does have a concept of hierarchical (parent-child) entities. In the datastore, the only operations that are supported are: get/put by key, inequality (<,

, =) filters, and a way to limit results that have a common ancestor

(key). Would this be enough to support BaseX?

Thanks,
