Randall Hauch commented on DNA-67:
----------------------------------

I'm starting to not like the PropertyValue interface.  Doesn't seem to add much usefulness, but it does add overhead.  And it seems like some of its functionality should really be part of Property: the PropertyType reference, and whether the property is null.  Conversion operations for the raw types (e.g., Binary, String, UUID, URI, etc.) should maybe even go someplace else, like in the PropertyValueFactory interface.  (Because, aren't conversion operations just creating copies of the values?)

> The federation engine needs a graph API for working with content.  The federation engine will obtain content from connectors through this API, and the cache will manage the graph instances.  Other components like sequencers, analyses, etc. could also make use of this API (on top of the cache, though).
