Fluidinfo

Fluidinfo, formerly named FluidDB until early 2011, is an online cloud data store based on an attribute-value centric data model. Fluidinfo is written in Python and characterized by a publicly writeable schema-less database that provides a query language, a fine-grained permissions model and promotes data sharing, both publicly and in groups. The lack of an underlying RDBMS structure may classify Fluidinfo as a type of publicly writeable "collective database".
