Mora - Mongo Rest API

REST server for accessing MongoDB documents and meta data

Documents

When querying on collections those parameters are available:

query  - use mongo shell syntax, e.g. {"size":42}
limit  - maximum number of documents in the result
skip   - offset in the result set
fields - comma separated list of (path-dotted) field names
sort   - comma separated list of (path-dotted) field names
extended_json - set to "true" to return responses in [MongoDB Extended JSON](http://docs.mongodb.org/manual/reference/mongodb-extended-json/) format
