Bug #1320

- CMS option "ANGEL" changed to "ANGEL 5.5" to emphasize that existing support is for the IMS packages generated by the 5.5 version.
  (More recent releases create IMS content packages with different packaging).

Consistent Wording: "Discussion Board"

XHTML:
Added quotation marks to HTML attribute values

Version headers for CVS, so one can immediately see the version of the packages.

Changes to support import of standalone question library from WebCT (d2lquestionlibrary type, with filename of questiondb.xml; items tagged as "objectbank" in XML file).
- rcardinality set to "Single" if only one answer is correct (even if questiondb.xml has attribute set to "Multiple").
- correctness of response based on numerical test of text defined by setvar tag.
- itemfeedback accumulated and displayed in <postanswerdate> block for all response types.

- Keep count of files renamed to report as files copied when reporting results of IMS import into CSTR.

Some changes for import of content from WebCT Campus Edition 4:
- Naming of sequence files now uses the title of the item identifier (with the IMS identifier key appended for uniqueness).
- for content files in my_files, file path used in src attribute in resource tag in a map is part which proceeds my_files in entry in hrefs array.
- .html files are only generated if there are links to include
General change:
- localization of content type titles

WebCT Campus Edition 4.1 differences
- varname attribute in <setvar> is set to que_score instead of answerValue
- <matimage> inside <presentation><flow><material>

Fix typo:
Replace webct4ce with webctce4

Modifications so WebCT Vista 4 learning modules are imported.  Change file name modifications so Spanish language characters are preserved in file names.

Removing >:utf8 directive when writing problems to file, as spanish characters were not being saved correctly.  Apparently need either both <:utf8 when reading in from source xml AND >:utf8 when writing to source or neither of them (tests run by Guy).  Adopting second of these for now.

Fixes so matching questions imported from WebCT Vista 4 IMS packages now work correctly.

Support for import of WebCT Vista 4 "Jumbled Sentence" question type.

Import of WebCT Vista 4 "Combination" question type supported (maps to LC problem with radioresponse).

Adding support for import of WebCT Vista 4 IMS packages. Work in progress.  True/False, string, shortanswer, multiple choice, essay all functional.   Matching, jumbled and combination still require work.  Work in progress.

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

Use relative paths in src, when constructing <img src="" /> tags in items imported into CTSR so images will load when viewing resources prior to publication of imported items.

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.

Can now convert BB6 pool and assessment questions to LON-CAPA problems. Some fixes made to bb6 parser.  Mapping of feedback items to hints still needed.

sub parse_bb6_assessment() complete.
sub write_bb6_questions() will be next.

Start on parser for BB6 assessments/pools.  Saving my work.

Do not need to decode entities in Web CT4 quiz DB import (already done by HTMLParser). Correct &nbsp as &nbsp; etc. Make img src tags xhtml compliant, while avoiding converting <img src /> to <img src / />.

Fix scope for unitid; units now imported.

foilgroup options need quotes.

Now converts all WebCT CE functions, except sum(), to LON-CAPA equivalents.

Additional conversions of WebCT math functions.  More to follow.

Stop script block appearing before <problem> tag as it confuses the colorful editor.

Put all XML/HTML cleanup into separate handler

Fetch remotely stored images, referred to img src tags, and store locally, and convert img tags.  Other fix-ups to BB5 import code.  xhtml compliance.

- ENV -> env

Correction to parsing of WebCT 4 quiz_properties files.  Include <param></param> entries (with randompick parameter) in homework sequences, where webCT4 questions were N of M picks (N < M). Also pass randompick parameter into make_structure() so that problem container is identified as .sequence instead of .page, when randompick applies.

Clean up. Remove or replace debugging to STDERR with logging via &logthis(). Cetegory info and settings hashes for webct4 question database need to be passed by reference to process_assessment() because questionDB.xml is only processed the first time process_assessment() is called.  Change to imsmanifest parser so quiz_properties attributes are stored.

Various fixes to import of questions from webct4 question database. Notably:
attempt to handle underspecified string response type questions, by assuming order of answers (in resprocessing area)  matches order of answer boxes in a multi-part problem.

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).

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.

Remove debugging output.

Import assessment questions from quizzes or surveys into DOCS as simple problems.

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).

Fix for an oversized %ENV when launching unzip. Required for 1.2

Suppress display of output from unzip. Fix bug.

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.

Make sure first item in sequence file is always set to type=start.  As we are no longer putting Blackboard announcements first in top level sequence folder, checkfor announcements is no longer required.

Fix so titles will be retrieved for items in the imsmanifest.xml file for ANGEL packages.

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

Continuing consolidation to support import of IMS packages into both construction space, and directly into DOCS. Calls to lonnet::userfileupload now included to allow unpacked files to propagate back to home server for the course, when the IMS import process is called from DOCS.

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
