Ensure proper processing when no explicit choice for folder has been made in step 4:

&Apache::lonnet::unescape -> &unescape
&Apache::lonnet::escape -> &escape

Existing webct4 code identified as appropriate for WebCT 4 Campus Edition. Vista to follow.

xhtml

- start_page

Remove redundant code now $chome is no longer required by &Apache::lonnet::process_coursefile().

Changes to argument list in lonnet::process_coursefile() - lonnet rev 1.638 - broke stuff.

- ENV -> env

Add option to import WebCT4 IMS package.  Work still required on import of questions and quizzes. Import of BB6 assessments also requires work (BB6 IMS packaging uses  QTI-type packaging for assessments unlike BB5).

Removing debugging code

User's choice of content types to import (e.g., only discussion boards, and quizzes) is now incorporated when building the LON-CAPA structure from the description of course organization in the IMS manifest file.  In addition, a .sequence file is now created for access to all questions contained in question pools.  Previously these questions were only accessible in the case of imports into CSTR.

Save each set of imported questions in a page (for an assessment) or in a sequence (for a pool).  Make sure directories are created, and replicated (if using DOCS to import into a course).  Distinguish between question import for CSTR and DOCS. Also some minor improvements in appearance.

Support for import of Blackboard 6 IMS exports (e.g. Concord RTT), and 'packages' within course content (Blackboard 5).

Set correct URL for inline images and linked files where IMS package import is via DOCS. Also fix some bugs in the parsing of Blackboard resource files.

Bug fixes. Make sure target directories exist, and timestamp is included in path to documents in .page files.

Switch & for + so buttons show correct wording

imsimport.pm - now allows choice of areas to be imported
imsprocessor.pm - fixes to consolidation
imsimportdocs.pm - modifications to accompany changes to imsprocessor.pm

Now allows specification of destination of top level sequence from IMS package (group import into current folder, or creation of a new folder). Propagation of files and folders added to /userfiles area on current server back to /userfiles area in lonUsers directory for course on home server.

Modularization of imsimport.pm -> imsprocessor.pm
imsprocessor.pm contains routines to allow import of IMS packages into both
an author's contrsuction space, and also into a course directly via the DOCS interface.

imsimportdocs provides the user interface for import on an IMS package directly into a course using the DOCS screen. Both are currently incomplete, as additional existing routines in imsimport.pm need to be modularized, (and ins ome cases modified) to support both DOCS and CSTR targets, before routines are moved to imsprocessor.pm
