@mire contribution of new theme to support easier development and branding.Provides the following:

1. A Restructured dri2xhtml base templates for easing locating specific XSLT templates
2. A Basic Theme based on the above restructured library that contains the templates that need customization most often in the UI.

dri2xhtml-alt

See committed source for dri2xhtml-alt here: http://scm.dspace.org/svn/repo/dspace/trunk/dspace-xmlui/dspace-xmlui-webapp/src/main/webapp/themes/dri2xhtml-alt/

Configuration and Installation

The alternative basic templates has been committed, and is currently dubbed "dri2xhtml-alt".
Any of the existing themes can be updated to reference this new set of templates by replacing in your theme.xsl:

<xsl:stylesheet xmlns:i18n="http://apache.org/cocoon/i18n/2.1"
	xmlns:dri="http://di.tamu.edu/DRI/1.0/"
	xmlns:mets="http://www.loc.gov/METS/"
	xmlns:xlink="http://www.w3.org/TR/xlink/"
	xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
	xmlns:dim="http://www.dspace.org/xmlns/dspace/dim"
	xmlns:xhtml="http://www.w3.org/1999/xhtml"
	xmlns:mods="http://www.loc.gov/mods/v3"
	xmlns:dc="http://purl.org/dc/elements/1.1/"
	xmlns="http://www.w3.org/1999/xhtml"
	exclude-result-prefixes="i18n dri mets xlink xsl dim xhtml mods dc">

    <!--
        comment out original dri2xhtml
        <xsl:import href="../dri2xhtml.xsl"/>
        and enable dri2xhtml-alt
    -->

    <xsl:import href="../dri2xhtml-alt/dri2xhtml.xsl"/>

    <xsl:output indent="yes"/>

Because the contents of dri2xhtml-alt is identical to the current dri2xhtml.xsl and its derivatives, updating any of the existing themes to reference the new dri2xhtml-alt should not impose any changes in the rendering of the pages.

Features

• No changes to existing templates found in legacy dri2xhtml
• Drops inclusion of Handlers other than DIM and Default
• Templates divided out into files so they can be more easily located, divided by Aspect, Page and Functionality

Basic Theme

Features

• reset css: ensures the styling is consequent amongst all browsers
• uses separate css files for different rendering situations: reset, base, print, handheld, ..., and the regular style.css which is similar to the one used in all other themes
• concatenation and minification ability for the css, js and json files:
  • This is disabled by default, and will need to be enabled in the configuration
  • The IncludePageMeta has been extended to generate URL's to the concatenated version of all css files using the same media tag (if enabled in config)
  • The ConcatenationReader has been created to return concatenated and minified versions of the css and js files
  • This is built to use the list of included css files, last modification timestamps, ... for caching purposes.
  • In order to enable this for any of the existing themes, the theme sitemap must be altered as well
• javascript loading if jquery is moved to bottom of page for fast loading
• uses new dri2xhtml-alt, and everything which is replaced in the theme, is included using the exact same hierarchy, for a good overview
• the rendering of item display and item lists has been completely redesigned
• the browser is no longer determined using the sitemap, but is determined in the page-structure.xsl: this is supposed to be more reliable
