Hi Evelthon,
actually there already is an MD5 checksum calculated for each
bitstream. It's easy to construct the URL in XSL - in your stylesheet
override the <xsl:template match="mets:file"> from item-view.xsl.
You'll need to add the
xmlns:util="org.dspace.app.xmlui.utils.XSLUtils"
xmlns:exdate="http://exslt.org/dates-and-times";
attributes to the stylesheet tag
and "util" and "exdate" to its "exclude-result-prefixes" attribute.
To construct the URL, use these values down in "a href":
<xsl:value-of select="@CHECKSUM"/>
<xsl:value-of select="exdate:date-time()"/>
That's the easy part - displaying the link. Now to actually make that
link work, you have to change
dspace-xmlui/dspace-xmlui-webapp/src/main/webapp/sitemap.xmap
starting from
<map:match pattern="bitstream/handle/*/*/**">
to include the new parameters - checksum and timestamp.
Then you have to make use of those parameters in
[dspace-src]/dspace-xmlui/dspace-xmlui-api/src/main/java/org/dspace/app/xmlui/cocoon/BitstreamReader.java
That should be enough to point you in the right direction.
Anyway, I'm wondering what's the reason you want to do this?
