Thus far, framing has only been defined over the merged node set from a JSON-LD document. Issue #118 [1] has been an open issue for some time to add support for named graphs when framing, and to allow framing to consider only the default graph. PR #438 [2] solves this, using an algorithm originally developed by Dave Longley. I’ve implemented as well in my Ruby JSON-LD processor. A formatted version of the spec can be viewed here [3]. Basically, if you use @graph at the top level of a frame, it will frame the default graph, rather than the merged graph. Within a sub-frame, the use of @graph will cause framing to occur based on the name of the subject of the nodes that match that frame. For example: { "@context": {"@vocab": "http://example.org/"}, "@type": "Library", "contains": { "@graph": {"@type": "Book"} } } Frames the merge graph, and adds any nodes of type Book from some other graph as values of “contains”. This is used as an example in [3]. Please review and provide feedback by Monday November 28th. Without objection, I will merge this at that time.
