UUID based NoSQL document store in/for Perl, ideal for graph storage, JSON DBs, etc. Usage is as simple as loading the library and configuring the object - no other processes or servers required (unless your chosen back-end is a DB engine).
Store any kind of data you want, even mixing document types within the same datastore.
Simple plug-in architectures, callbacks, and configurations to modify, extend, or intercept nearly any operation.
Under active development, better documentation forthcoming.
