Collaborating using different object models

A system comprising:

• one or more processors;
• and
• a memory storing one or more databases and instructions that, when executed by the one or more processors, cause the system to perform:
• receiving data corresponding to one or more source objects, the source objects being stored in a first object model, and each of the source objects being associated with information describing an entity;
• determining matches between the respective information associated with the one or more source objects and respective information associated with one or more target objects based on a query, the target objects being stored in a second object model;
• ranking the one or more source objects based at least in part on the matches;
• and
• providing a list of the ranked source objects through an interface, the interface indicating a number of matching target objects for each of the source objects.
