Andy Seaborne commented on JENA-1971:
-------------------------------------
Jena 4.5.0 switches from JSON-LD 1.0 (jsonld-java) to JSON-LD 1.1
(titanium-json-ld).
Output in JSON-LD 1.1 is only moderately "pretty". It only uses prefixes
defined in the graph or dataset being printed. If there is a prefix for
http://zam.com/ns/, it does use the prefix name form in both examples.

> Key: JENA-1971
> URL: https://issues.apache.org/jira/browse/JENA-1971
> Project: Apache Jena
> Issue Type: Bug
> Components: JSON-LD
> Affects Versions: Jena 3.16.0
> Environment: The code and data used can be found at:

> https://github.com/ebremer/jenabug/blob/master/src/main/java/com/demo/JSONLDBUG.java
> Reporter: Erich Bremer
> Priority: Major

> 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" : {
