> Exporting this TTL from a Model:
> {noformat}
> <http://me.com> <http://zam.com/ns/cheesey> "WOW" .
> #<http://me.com> <http://zam.com/ns/cheesey> ( "png" "jpg" "tif" "gif" ) .
> <http://notme.com> <http://zam.com/ns/cheesey> ( "png" "jpg" "tif" "gif" ) .
> <http://www.twotowers.com/a>
> <http://shadowfax.com/ns/height>
> "262144"^^<http://www.w3.org/2001/XMLSchema#int> ;
> <http://shadowfax.com/ns/width>
> "262144"^^<http://www.w3.org/2001/XMLSchema#int> .
> {noformat}
> Yields the expected JSONLD:
> {noformat}
> {
> "@graph" : [ {
> "@id" : "http://me.com";,
> "cheesey" : "WOW"
> }, {
> "@id" : "http://notme.com";,
> "cheesey" : {
> "@list" : [ "png", "jpg", "tif", "gif" ]
> }
> }, {
> "@id" : "http://www.twotowers.com/a";,
> "height" : "262144",
> "width" : "262144"
> } ],
> "@context" : {
> "rest" : {
> "@id" : "http://www.w3.org/1999/02/22-rdf-syntax-ns#rest";,
> "@type" : "@id"
> },
> "first" : {
> "@id" : "http://www.w3.org/1999/02/22-rdf-syntax-ns#first";
> },
> "cheesey" : {
> "@id" : "http://zam.com/ns/cheesey";
> },
> "width" : {
> "@id" : "http://shadowfax.com/ns/width";,
> "@type" : "http://www.w3.org/2001/XMLSchema#int";
> },
> "height" : {
> "@id" : "http://shadowfax.com/ns/height";,
> "@type" : "http://www.w3.org/2001/XMLSchema#int";
> }
> }
> }
> {noformat}
> However, removing the one comment in the TTL and adding an additional triple
> prevents the compaction of the property "cheesey" from being shortened:
> {noformat}
> {
> "@graph" : [ {
> "@id" : "http://me.com";,
> "http://zam.com/ns/cheesey"; : [ {
> "@list" : [ "png", "jpg", "tif", "gif" ]
> }, "WOW" ]
> }, {
> "@id" : "http://notme.com";,
> "http://zam.com/ns/cheesey"; : {
> "@list" : [ "png", "jpg", "tif", "gif" ]
> }
> }, {
> "@id" : "http://www.twotowers.com/a";,
> "height" : "262144",
> "width" : "262144"
> } ],
> "@context" : {
> "rest" : {
> "@id" : "http://www.w3.org/1999/02/22-rdf-syntax-ns#rest";,
> "@type" : "@id"
> },
> "first" : {
> "@id" : "http://www.w3.org/1999/02/22-rdf-syntax-ns#first";
> },
> "cheesey" : {
