h1. Overview {anchor:id=SOCref.Social_JCR_Structure.Overview}
Like any other eXo's products, eXo Social fully complies the JCR standard to store data (identity, profile, activity, space and relationship).
The eXo Social JCR structure is organized to conform to the data storage for the individual purpose of eXo Social. With this structure, it is easy for you to manage and access the data properly.

See the eXo Social JCR structure in the chart below:

The root node of Social workspace is _/production/_ which consists of two child nodes named _{noformat}soc:providers{noformat}_, and _{noformat}soc:spaces{noformat}_.

h1. soc:providers  {anchor:id=SOCref.Social_JCR_Structure.socproviders}
The _{noformat}soc:providers{noformat}_ node is used to store the provider entities. In eXo Social, there are two built-in provider entities, including _organization_, and _space_.
