Major API Refactor: The API functionality has been refactored to require creating an Opal object for establishing a connection. Methods are now called on this object for interacting with the LMS API, replacing the previous function-based approach.
Added a verify_qti() function to validate XML documents against the QTI v2.1 schema. Two schema versions are supported: the original IMS Global schema and an extended version that permits additional HTML tags.
Added new constructor functions assessmentTest(), assessmentTestOpal(), assessmentSection().
The default values of the "academic_grading" parameter/slot have been updated in the functions assessmentTest(), assessmentTestOpal(), test(), and in the classes AssessmentTest and AssessmentTestOpal. This parameter/slot is a named numeric vector that defines the grade table shown to candidates as feedback at the end of the test. The updated default follows the German grading system: gt <- c("1.0" = 0.95, "1.3" = 0.9, "1.7" = 0.85, "2.0" = 0.8, "2.3" = 0.75, "2.7" = 0.7, "3.0" = 0.65, "3.3" = 0.6, "3.7" = 0.55, "4.0" = 0.5, "5.0" = 0), where each grade corresponds to the minimum percentage score required to achieve it. To disable the grading table at the end of the test, set this parameter to NA_real_.
Generic functions are now exported to allow advanced users to extend the functionality of S4 classes (createItemBody(), createResponseDeclaration(), createOutcomeDeclaration(), createResponseProcessing(), createText()).
Added support for the preview_feedback option within 'params' in the YAML section of R Markdown files.
Renamed the service name in the keyring system credential storage to "rqtiopal".
Renamed the "contributor" slot in QtiContributor to 'name'.
QTIJS rendering (DirectedPair type, round Score and Maxscore values).
Added a '<div>' tag as a root child within the 'itemBody' element for Entry type tasks to ensure compatibility with the LMS OpenOlat.
The functions qti_metadata() and qti_contributor() have been deprecated. Use qtiMetadata() and qtiContributor() instead.
The 'question_type' column has been removed from the data frame returned by extract_result(level = "item").
Fix parsing R Markdown files with tables according the latest pandoc version.
Fix extract_results(level="items") for Ordering type, when candidate response
is not given.
Fix error at createQtitask(obj, zip=TRUE).
New API OPAL function get_course_elements() returns dataframe with elements of
the course by course id.
New API OPAL function get_course_results() returns an xml with data about
results by course id and node id.
New API OPAL function publish_courses() for publishing a course by Resource ID.
method createQtiTask() can create XML or zip files, to control this use
parameter zip=TRUE.
QTIJS rendering shows feedback and score for tasks.
Handle problem with xsd scheme for xml validation.
Handle some problems with html and mathml entities.
Improved the appearance of the tasks in QTIJS viewer.
Added constructor functions for task classes: singleChoice(), multipleChoice(),
essay(), ordering(), entry(), directedPair(), oneInColTable(), oneInRowTable(), myltipleChoiceTable().
Added constructor functions for content of Entry class: numericGap(), textGap(),
textGapOpal(), inlineChoice().
Added constructor functions for the feedback objects: modalFeedback(),
correctFeedback(), wrongFeedback().
Added the ability to upload SURVEY resource type to Opal using the API. The upload2opal() function now includes a new parameter, "as_survey", which allows you to specify the resource type. Set "as_survey = TRUE" to upload as a SURVEY
resource type.
Added the ability to put metadata in the manifest file for tests. To store metadata information AssessmentItem and AssessmentTest use slot "@metadata" that takes QtiMetadata (and QtiContributor inside) classes as type. Two construction functions have been added to create objects: qti_metadata() and qti_contributor().
Added the missing qti.js for rendering Rmd-files with tasks.
Added processing of the pandoc --embed-resources parameter for pandoc versions < 2.19.
AssessmentItem, AssessmentSection and AssessmentTest objects are checked for compliance with QTI requirements.
