Hi,
Yes, you can do this – at least in 5.8 XMLUI Mirage2 we are.
We’ve first got variables:
<xsl:variable name="file_id"
select="jstring:replaceAll(jstring:replaceAll(string(@ADMID), '_METSRIGHTS',
''), 'rightsMD_', '')"/>
<xsl:variable name="rights_declaration"
select="../../../mets:amdSec/mets:rightsMD[@ID = concat('rightsMD_', $file_id,
'_METSRIGHTS')]/mets:mdWrap/mets:xmlData/rights:RightsDeclarationMD"/>
<xsl:variable name="rights_context"
select="$rights_declaration/rights:Context"/>
<xsl:variable name="users">
<xsl:for-each select="$rights_declaration/*">
<xsl:value-of select="rights:UserName"/>
<xsl:choose>
<xsl:when test="rights:UserName/@USERTYPE = 'GROUP'">
<xsl:text> (group)</xsl:text>
</xsl:when>
<xsl:when test="rights:UserName/@USERTYPE = 'INDIVIDUAL'">
<xsl:text> (individual)</xsl:text>
</xsl:when>
</xsl:choose>
<xsl:if test="position() != last()">, </xsl:if>
</xsl:for-each>
</xsl:variable>
Then we can do a test like:
<xsl:when test="$users='AQD (group)'">
Other things we test for are whether any embargo has expired:
test="$rights_context/@in-effect)='true'"
and whether it’s available for the current user:
test="contains(mets:FLocat[@LOCTYPE='URL']/@xlink:href,'isAllowed=y')"
If you need to troubleshoot you can see the raw METS xml at eg
https://example.com/metadata/handle/12345/1234/mets.xml

Subject: [dspace-tech] How to check if bitstream is readable by a specific group
Dear All,
We are using DSpace 6.3 XMLUI Mirage2 theme. I have enabled IP based
authentication in which all users coming from our internal network will
automatically become members of a special group (AQD). What I want to achieve
is to display a logo beside the bitstream link to identify it as downloadable
only for the group AQD. Looking at the item-view.xsl, I see that the lock
glyphicon is rendered if the bistream URL contains the 'isAllowed=n' text. I
cannot use that logic because not all restricted bitstreams are readable by the
group AQD (some are for Admins only). Is there a way using just xslt to check
whether the bitstream is readable by a specific group?
Thanks in advance!
