My RDF knowledge is rudimentary, but what i can say for sure the "context" link relation and "@context" from JSON-LD are different things. Here is what JSON-LD[1] documentation says: "The secret lies in the @context, which instructs Linked Data-aware processors on how to interpret the JSON object." which is not the case for the "context" link relation... it's much simpler and must be used to indicate that a resource is a member of another resource and only in cases when we do not have collection/item relationships. For example if i share resource URI which is a member of another resource i can use the "context" link rel to inform processing agent that shared resource is a member of another resource.

No, title attribute is only used for user interfaces i do not think anyone uses it for other purposes. In my apps i only use rel attribute values to decide which link to follow.
