Release Notes 2.3 - Die wichtigsten Neuerungen

ZMS 2.3: CSS-Tuning, WAI, SCORM2004

Oberflächlich betrachtet hat sich wenig geändert bei der neuen Version ZMS 2.3; intern sieht es jedoch anders aus: das Release 2.3 zeichnet sich durch eine strukturelle Überarbeitung aller Standard-Objekte aus. Die HTML-Ausgabe enthält keine Tabellenkonstrukte mehr und setzt auf div-Elemente bzw. CSS. Konsequenterweise wurde auch das Template-Konzept überarbeitet, um eine WAI/Accessibility-konforme Ausgabe zu erleichtern.
Im Detail sind folgende Aspekte in das System eingarbeitet worden:

Über das Meta-Attribut "PageExt" können für jedes Dokument frei wählbare Datei-Erweiterungen (*.html, *.php, *.asp etc.) definiert werden; diese erleichtern die Integration von ZMS-genrierten Dokumenten in andere Programmierumgebungen (z.B. beim statischen Export).

Die Template-Benamung hat sich nach folgendem Prinzip geändert:
Ein sog. "pageelement" ist funktionale Einheit, eine sog. "pageregion" ist eine Layoutzone. Das pageregion-Modell orientiert sich am prinzipiellen Layoutkonzept von XML-FO (Formatting Objekcts). Beispiel: Ein Template "pageelement_Menu" enthält den Code für die Generierung einer Menü-Liste während das Template pageregionTop z.B. das funktionale Template pageelement_Menu aufruft und damit im Seiten-Kopf platziert.

MASTERTEMPLATES
    standard_html_request: Init Request
    standard_html_header: before content
    standard_html_footer: after content

PAGEREGIONS / LAYOUT
    pageregionTop: page top
    pageregionLeft: Left Column [Macro-Nav]
    pageregionBefore: Before Content
    pageregionAfter: After Content
    pageregionRight: Right Column [Context]
    pageregionBottom: Page Bottom

HTMLHEAD
    headDoctype: DOCTYPE declaration
    headLinkrelations: LINK elements
    headCSS: Style elements
    headBodytag: HTML body tag

FUNCTIONAL PAGEELEMENTS
    pageelement_Logo: Logo
    pageelement_Menu: channel bar
    pageelement_Macronavigation: main navigation
    pageelement_Micronavigation: path navigation
    pageelement_Search: search
    pageelement_Searchresults: search
    pageelement_Languageselect: language selector
    pageelement_Styleselect: styling selector
    pageelement_Headline: document title
    pageelement_Description: document description
    pageelement_TOC: document overview
    pageelement_Index: table of content
    pageelement_Links: related documents and links
    pageelement_Teaser: teaser elements
    pageelement_Copyright: copyright information

Hinweis: Die alten Templates aus den Vorgängerversionen sind natürlich prinzipiell weiter einsetzbar; grundsätzlich ist bei Bedarf weiterhin auch das Arbeiten mit einer völlig anderen Template-Nomenklatur möglich.

Die neuen inline-Elemente für Textobjekte (abbreviation, acronym, language) helfen dabei WAI-konforme Inhalte auszuzeichnen; dies betrifft in erster Linie Zeichenketten, die für die Ausgabe über Screenreader detaillierter deklariert werden sollen.

Die Konfiguration von Multi-Sites (Master-Client-Konstrukte) wurde optimiert, indem die Vererbung von Objekten und Attributen überarbeitet wurde; dies bestrifft in erster Linie die Vererbung von Sprach-Dictionaries und eine Restriktion des Löschens von akquirierten Objektdefintionen.

Das ZMS-interne Interface zur Pflege von CSS-Definitionen kann mehrere CSS-Files verarbeiten; zu diesem Zweck kann man über eine Selectliste eine beliebige Zahl von CSS-Varianten initialisieren. Diese werden über einen fortlaufenden Index automatisch benamt.

Der Export-Mechanismus ist in der Lage, auch DTML-generierte Zusatz-Dateien auszugeben; dies ist insbesondere relevamt für die Generierung von SCORM-konpatiblen Content-Strömen. Der dahinterstehende Mechnismus rendert SpecObj-Elemente vom Typ DTML-Methode und platziert das Resultat in den entsprechend exportierten Folder, der das mit der Methode attributierte Content-Object umschliesst.

Das color-Objekt resultiert aus dem Parsing der CSS-Defintitionen, deren Elemente einen Substring "Color" enthalten (wie z.B. neutralColorStrong); ZMS erzeugt eine colormap, die aus den Elementnamen und den entsprechenden Werten besteht. Das color-Objekt kann als Datentyp in ein SpecialObjekt eingesetzt werden und liefert alle im Farbschema verfügbaren Farbwerte in einer entsprechend eingefärbten Liste zur Auswahl.

Für die Standard-Objekte (ZMSTextarea, ZMSTable, ZMSGraphic, ZMSTeaserelement) liefert ZMS default-CSS-Elemente; diese werden dem in der Konfiguration definerbaren CSS vorangestellt. Die verbestimmten Element-Defintionen können somit leicht überschrieben. Die Benamung der CSS-Element ist insofern mit dem neuen Template-Namen identisch, als dass jeder Template-Code mit einem entsprechend funktional benamten div-Element umschlossen ist. Bsp: das funktionale Template "pageelement_Menu" wird von <div id="Menu"> eingeleitet. Gemäß der Objekt-Hierachie lassen sich per CSS auf diese Weise die Sub-Elemente (ul, li, a) eindeutig identifizieren.
Wenn man die Seitenkonstruktion komplett ins CSS verlagert, wird dieses naturgemäß komplexer, während der Template-Code wesentlich schlanker wird.
