Should JSON representation of REST resources use URIs for related resources? -

-

is best practice of using uris in json (or xml) representation of rest resources, example

for example resource has list of attachments, every attachment has id can used retrieve using url http://myserver.com/resources/attachments/: 

{     filename: "screenshot.png"     contenttype: "application/octet-stream"     id: 52004 }

should add uri element like

{     filename: "screenshot.png"     contenttype: "application/octet-stream"     id: 52004     uri: /resources/attachments/52004 }

yes, think should include link each item in collection. api not restful (and more importantly, not useful) without links. if think human client rather have link instructions on how request item id, same applies non-human client. should give client idea of how item relates current resource providing link relationship:

link : { uri: "/resources/attachments/52004", rel: "/rels/file-attachment" }

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
