• From your FlexPaper download, copy the css, js, and locale data folders into /dspace/modules/xmlui/src/main/webapp/static/flexpaper

• Create the following in /dspace/modules/xmlui/src/main/webapps/static/: 

  • template.html

  • bookview-banner.html,

  • bookview-banner.js

  • Source for these files
    • https://gist.github.com/terrywbrady/487acdb7d5bf779036bb
    • Replace $$$YOUR_KEY_HERE$$ with your license key
    • Customize bookview-banner.html to match your theme

• Add the following to /dspace/modules/xmlui/src/main/webapp/sitemap.xmap

  Code Block
  lang xml
  <map:match pattern="static/**.js"> <map:read type="ConcatenationReader" src="static/{1}.js"> <map:parameter name="requestQueryString" value="{request:queryString}"/> </map:read> </map:match> <map:match pattern="static/**.css"> <map:read type="ConcatenationReader" src="static/{1}.css"> <map:parameter name="requestQueryString" value="{request:queryString}"/> </map:read> </map:match> <map:match pattern="*.txt"> <map:read src="static/{1}.txt"/> </map:match>
