It always takes new eyes like ours to uncover these kinds of issues, those working with the code for any length of time will have the different IDs etched into their minds.
Yes, it makes sense inside Wookie, but how these are exposed in the representations of Widget and WidgetInstance in XML doesn't really help.
Here's a widget: <?xml version="1.0" encoding="UTF-8"?> <widgets><widget id="3" identifier="http://www.getwookie.org/widgets/todo"; width="320" height="460" version="">
<title short="">Ta-Da!</title>

</widget>
</widgets>
As you can see there is:
widget.id = the internal id used for the widget (i.e. its database key)
widget.identifier = the external IRI used to globally identify the
widget. (In the code this is sometimes called the widget guid. In W3C
Widgets this is called the widget id attribute).
A request for information about the widget uses widget.id, e.g.
GET /wookie/widgets/3
A request for a new widget instance uses widget identifier, e.g.
POST /wookie/widgetinstances
api_key=TEST
userid=test
shareddatakey=test
widgetid=http://www.getwookie.org/widgets/todo
Here's a widget instance:
<?xml version="1.0" encoding="UTF-8"?>
<widgetdata>
<url>http://localhost:8080/wookie/wservices/www.getwookie.org/widgets/todo/index.html?idkey=ELrI91u2Oi.sl.A1Yt9NqOBDkbfoB4.eq.&proxy=http://localhost:8080/wookie/proxy&st=wookie%3A89wrKZFnvFSyAOQbsc%2B7JSYgexSEgUxKBGCajZffBt1zGQchTpFpoyLga7wcN6agQzTXiz8JoE4RDciuBPFyG2%2FPXjk%2BC7Xdgeps2btrVPpZ4%2FvrGLuYdhQ1GXsQ7680QaKE6WNXs2eMYaRfm7PZVZxU9otmA%2BR%2BE1Y5BpnF3Pg0N6fB1PUmIfVPO4281uE23r8kgw%3D%3D

<title>Ta-Da!</title>
<height>460</height>
<width>320</width>
<maximize>false</maximize>
</widgetdata>
widgetinstance.identifier = the hash of the widget instance composite
key (same as idkey param in widgetinstance.url)
So not very consistent unfortunately.The representations of all objects are created by classes in the org.apache.wookie.helper package - you could also extend these, for example, to produce alternate representations using JSON as well as XML, and to tweak the output to be more consistent and obvious.
