Irene,

You understand exactly. SHACL should support general, disconnected
graphs. However, OSLC Resource Shapes does not. It assumes there is an
initial root node and only let's you express constraints that are
rooted at nodes that can be reached from the initial root node by
traversing properties in the forward direction. SHACL must avoid this
limitation.
