1.1 bowersj2 2:
1.4 ! lira 3: LON-CAPA provides several types of resources for organizing your course website.
! 4: Resource roles are determined by file extension. Valid extensions are:
! 5: .xml, .html, .xhtml, .htm, .xhtm, .problem, .page, .sequence, .rights,
! 6: .sty, .task, .library, .js, .css, .txt.
1.1 bowersj2 7:
8: \begin{itemize}
1.4 ! lira 9: \item A \textbf{.css} cascading style sheet file \index{.css}\index{css}\index{cascading style sheet}
! 10: can be published to use in multiple courses.
! 11: Use of a specific CSS style within a resource can be set using an html tag within a text
! 12: block that refers to a class by name, where the class is included in the
! 13: published css file. You would specify use
! 14: of the css file with a \textless link\textgreater tag, and indicate a file dependency with
! 15: an allow tag (if the \textless allow\textgreater tag is not specified LON-CAPA should add it
! 16: at the first publication step).
! 17:
! 18: \begin{verbatim}
! 19: <startouttext />
! 20: <link rel="stylesheet" index="11"
! 21: href="/res/yourname/yourpath/testcss.css" type="text/css" />
! 22: <span class="Yellow">After the Earth and Mars, which other body in our
! 23: solar system is thought to be the next most likely site for finding
! 24: life?</span><endouttext />
! 25: <allow src="/res/yourname/yourpath/testcss.css" />
! 26:
! 27: where testcss.css contains:
! 28:
! 29: .Yellow {
! 30: color: yellow;
! 31: }
! 32: \end{verbatim}
! 33:
! 34: It also possible to indicate use of a css file within a course,
! 35: course-wide, for a specific folder, or specific resource etc, by setting
! 36: the parameter: CSS file to link [Part: 0] (cssfile).
! 37:
! 38: \item A \textbf{.html} HTML file\index{HTML file}\index{content page}\index{.htm, .html, xhtm, xhtml},
! 39: (formerly known as a Content Page), displays course content. It is a conventional HTML page.
! 40: These resources use the extension
! 41: {}``.html''. By using the "New File..." dropdown, you can enter a file name with one
! 42: of the other extensions, htm, xhtml, xhtm, xml. For more information see the section \ref{Content_Page_Overview}.
! 43:
! 44: Although the extensions: xhtml and xhtm imply that the file should be
! 45: xhtml compliant (i.e., be a valid document, according to w3c validation
! 46: meaning (amongst other things): all elements closed; attributes
! 47: case-sensitive; attributes required by certain elements, certain
! 48: specials characters need to be included as entities in some attributes
! 49: etc.), LON-CAPA does not test whether a document with an xhtml extension
! 50: is actually valid xhtml.
! 51:
! 52: Files of type .xml are supported for legacy files, but it is suggested that new files
! 53: are one of the html varieties. See also the .libary file description for xml.
! 54:
! 55: \item A \textbf{.problem} Problem\index{problem}\index{.problem} resource represents problems for the students
1.1 bowersj2 56: to solve, with answers stored in the system. These resources are stored in
1.4 ! lira 57: files that must use the extension {}``.problem''. Problems are coded in a combination
! 58: of Perl and xml markup tags. Most of this manual concerns authoring problems. For an overview
! 59: see the section \ref{Problem_Types}
! 60:
! 61: \item A \textbf{.page} Page\index{page}\index{.page} is a type of \textbf{Map}\index{map} which
! 62: is used to join other resources together into one HTML page. For example,
! 63: a page of problems will appears as a problem set. These resources are stored
! 64: in files that must use the extension {}``.page''.
! 65:
! 66: For performance purposes it is best not to include too may resources in a
! 67: .page (8 would be a good limit; and likely fewer if maxima or R are
! 68: required for computation). The course editor offers similar tool called
! 69: a "Composite page" which resides within a course rather than in the published
! 70: repository.
! 71:
! 72: The underying XML structure, and
! 73: behavior of a .page file are the same as used for a "Composite page",
! 74: which can be added to a course using the Course Editor. One difference
! 75: between the two is that for a .page in Authoring Space, one of the
! 76: Authoring Space editors (Simple Edit or Advanced Edit) will be used to
! 77: modify the contents of the file, whereas for a Composite Page, the
! 78: course editor is used.
! 79:
! 80: Options for reuse of a course Composite page are: (a) use cloning to copy
! 81: everything from the old course to the new; (b) as course coordinator,
! 82: copy the Composite map into the Course Editor's clipboard, change role to
! 83: course coordintator in a different course, and past the item
! 84: into the other course from the Course editor's clipboard.
! 85:
! 86: The course manual describes ways to combine resources in folders,
! 87: which is an alternative to creating composite pages. The advantage of a .page
! 88: is that they can be printed all at once. The disadvantage is that once a .page
! 89: is published, the contents are more difficult to change. Publishing a .page
! 90: in the repository is suggested if the content does not need to change.
! 91:
! 92: For more information on .pages, see the section \ref{Sequence_Page_Maps}
! 93:
! 94: \item A \textbf{.js} javascript file contains javascript code which might be referenced
! 95: with HTML in a textblock in a LON-CAPA problem in a manner similar to a .css file.
! 96:
! 97: \item A \textbf{.library} library file contains LON-CAPA XML which can be imported into
! 98: other .problem files. Typically a .library file will hold commonly used subroutines, or
! 99: data structures (to be called in
! 100: LON-CAPA perl script blocks). It is included in a problem in the
! 101: colorful editor by using the "Import a File" selection in a dropdown
! 102: list in the colorful editor.
! 103:
! 104: \item A \textbf{.sequence} sequence\index{sequence}\index{.sequence} is a type of \textbf{Map}\index{map}
1.1 bowersj2 105: which is used to link other resources together. The users of this resource
1.4 ! lira 106: can use links to follow the
1.1 bowersj2 107: sequence. Sequences are stored in files that must use the extension {}``.sequence''.
108: Sequences can contain other sequences and pages.
1.4 ! lira 109:
! 110: A published sequence contains XML which describes which LON-CAPA resources are to be
! 111: grouped together in a folder. If a .sequence file is imported in its entirety
! 112: then there is limited
! 113: control over which specific resources are shown, and in which order. The
! 114: "Randomorder" and "Randompick" checkboxes in the Course Editor can be
! 115: used to cause the resources to be displayed in a randomorder (randomized
! 116: for each user), and to display M of the total N resources in the
! 117: sequence (again the choice of which M are shown is randomized for each
! 118: user). By contrast, if the "Import from Assembled Map",
! 119: a "Select Map" link will allow all resources in the
! 120: published sequence to be imported into the current folder, as distinct
! 121: resources, allowing them to be reordered, and cut/removed, as preferred
! 122: using the standard Course Editor tools.
! 123:
! 124: Conditional sequences are published sequence files for which conditions
! 125: have been specified for one or more links between resources in the map.
! 126: These have to be created using the "Advanced Edit" button when creating
! 127: a new sequence file in Authoring Space. These are the types of sequence
! 128: for which a student's progress through a series of resources can be
! 129: specified. Grading of conditional sequences can be complicated.
! 130:
! 131: \item A .rights file is used to specify custom access rights for a published
! 132: resource. The access rights to apply to a specific resource are
! 133: specified on publication (or republication) of the resource. A .rights
! 134: file also must be published to be selectable during resource publication
! 135: as a "Custom Distribution File" when "Customized right of use ..." is selected from the
! 136: "Copyright/Distribution" dropdown list. See the section \ref{Publishing_Copyright}.
! 137:
! 138: \item A .sty is a LON-CAPA style file used to apply custom styling to specific
! 139: tags in a LON-CAPA problem. The styles defined in the file can be applied to display of all
! 140: resources in a course using:
! 141:
! 142: Main Menu -\textgreater Modify course configuration -\textgreater Display of resources
! 143: (checked) + click "Display" button -\textgreater Click "Select Style File" link (
! 144: Default XML style file item) to launch window to select published .sty
! 145: file, then click "Save Changes" in main window.
! 146:
! 147: Style files can contain different instructions for different
! 148: targets (e.g., web or tex). For example, the following style file would replace
! 149: the \textless h1\textgreater-tag in all
! 150: incorporated pages by the annoying \textless blink\textgreater-tag:
! 151:
! 152: \begin{verbatim}
! 153: <definetag name = "h1">
! 154: <meta></meta>
! 155: <render>
! 156: <web><blink></web>
! 157: <tex>\section{</tex>
! 158: <latexsource>\section{</latexsource>
! 159: </render>
! 160: </definetag>
! 161:
! 162:
! 163: <definetag name = "/h1">
! 164: <meta></meta>
! 165: <render>
! 166: <web></blink></web>
! 167: <tex>}</tex>
! 168: <latexsource>}</latexsource>
! 169: </render>
! 170: </definetag>
! 171: \end{verbatim}
! 172:
! 173: To use the .sty in a course, within the course, In PARM - "Set Course Environment"
! 174: you can specify a style file for your course under "Default XML Style File".
! 175:
! 176: When printing, LON-CAPA will use the tex \textbackslash section as
! 177: \textless h1\textgreater-rendering.
! 178:
! 179: Note that .css is perhaps a more modern way to acheive formatting.
! 180:
! 181: \item A \textbf{.task} task file is a bridge task file. Bridge tasks permit
! 182: assessment using rubrics. See the section \ref{BridgeTask_About}.
