When performing Save as... to existing feed location, ask user for confirmation 
of overwrite before 
proceeding

Attempt to open a non-existent workspace; nothing happens
Try again to access "Open..." dialog: dialog does not appear

Precautions should be taken to ensure user activity does not take place while a 
workspace is being 
read or written.

A modal dialog display for issue 1 
(http://code.google.com/p/shuffl/issues/detail?id=1) might 
resolve this.

If there is an I/O error during load/save of the workspace, the program can end 
up in an 
unpredictable and unreported error state. Take steps to catch erroros and 
report them, maybe in 
the form of a progress dialog while load/store is being performed.

Workspace and card data can be loaded from an arbitrary URI that does not 
respond to AtomPub 
requests.  In such cases, "Save" operations should be disabled, requiring 
instead a "Save new...".

Also, prevent editing cards that cannot be saved.

Also, prevent moving or editing cards in an unsaveable workspace.

This logic should probably be implemented along with a plug-in framework for 
backend storage, 
and refactoring the load logic to accept a storage object rather than just a 
URI.

To reproduce:
Create a card of type freetext.
Populate with several lines of text so that text is longer than display area
Try to scroll:  the up/down arrows in the scroll bar work OK, but attempting to 
drag the scroll bar 
handle simply results in dragging the card around.

This is probably caused by the card-drag handler intercepting the scrollbars 
drag handler.  I need 
to determine how to (a) change priority of intercept, or (b) disable 
card-dragging for the scrollbar 
area.

Shuffl currently has no provision for deleting cards from a workspace.

I'm currently thinking that dragging to a rubbish bin in the stockbar should 
remove the card from 
the workspace, but preserve its data until such time as the rubbish is emptied. 
 It should be 
possible to drag items back from the rubbish area to the workspace.

The project needs a CLA in order to be able to accept third party
contributions.

The attached is a CLA document that has already been approved by the
University of Oxford legal peeps, I have checked that they are happy for
you to use it for Shuffl as well.

The CLA leaves copyright with the contributor but grants permission to
release the contribution under an open source licence.

Note that this is only an individual CLA, we also need to create a
corporate CLA. This is an even simpler document and I will take one through
Oxfords legal team ASAP.

What steps will reproduce the problem?
1.  var rdfdatabank = jQuery.rdf.databank()
            .base("")
            .prefix("rdf", "http://www.w3.org/1999/02/22-rdf-syntax-ns#")
            .prefix("shuffl", "http://purl.org/NET/Shuffl/vocab#")
            .add("<http://example.com/card#id_1> rdf:type shuffl:Card")
            .add("<http://example.com/card#id_1> shuffl:id \"id_1\"")
             .add("<http://example.com/card#id_2> rdf:type shuffl:Card")
            .add("<http://example.com/card#id_2> shuffl:id \"id_2\"")
            ;
2. var jron = jQuery.RDFtoJRON(rdfdatabank);
3. alert (JSON.stringify(jron));

What is the expected output? What do you see instead?

The JRON output containing 4 triples instead an exception is generated.
What version of the product are you using? On what operating system?
The latest version.

Please provide any additional information below.
The bug is located in this bloc of code :
550 for (subjkey in rdfsubjects)
551 {
552 var stmt = statements_toJRON(databank, rdfsubjects, bnodeobjects, subjkey, 
jron);
553 if (stmt) statements.push(stmt);
554 };
555 if (statements.length == 1)
556 {
557 $.extend(jron, statements[0]);
558 }
559 else
560 {
561 var e = "Statements exist for multiple subjects - JRON representation not 
determined";
562  log.error(e);
563 for (var i = 0 ; i < statements.length ; i += 1)
564 {
565  log.debug("- ["+i+"]: "+$.toJSON(statements[i]));
566 }
567 throw e;
568 };
569 return jron;
570 }
