NkDOMAIN

NkDOMAIN is an Erlang framework to load an manage complex distributed, multi-tenant configurations in a riak_core cluster.

NkDOMAIN can read domain configurations from YAML files, JSON files or Erlang maps, it checks its syntaxis and creates correspondig Erlang processes distributed in the cluster, saving the objects in a NkBASE database, for example:

By default, NkDOMAIN recognizes:

Domains and subdomains (proyects) to any level. Inside domains, the following elements are recognized:
- Groups and subgroups
- Users
- Services
- Nodesets
Aliases
Tokens

Some other features are:

Very high perfomance, it can scale to millions of objects.
Sophisticated role management, based on NkROLE.
Objects are distributed in the cluster using NkDIST. They can be permanent (like domains) or temporary (like users). Temporary objects are automatically reloaded if necessary.
Domains can be re-loaded at any time, only modified items will be processed.
Any element can be removed, and the depending elements (subgroups, etc.) will also be deleted.
Domains and users can have any number of aliases.
Full authentication token management, for users or any other object.
Services are started at all nodes of the cluster automatically.

NkDOMAIN is not yet ready for normal use, but most of it is complete. See the included tests for examples of use.
