Kia ora koutou,
Has anyone played around with Twitter cards and/or Open Graph with Dspace? The
goal being that, if someone tweets a link to an item in the repository, Twitter
(or Facebook or whoever) automatically displays a little preview of the item’s
title, thumbnail etc. This seems likely to improve click-throughs/engagement.
I’ve edited page-structure.xsl (we’re on XMLUI, Mirage2) to get some basic
metadata in – following the Google Scholar Metadata section:
<!-- Add Open Graph tags for
appearance on social media -->
<meta property="og:type"
content="article"/>
<meta property="og:site_name"
content="Research@Lincoln"/>
<meta property="og:image"
content="https://ltl.lincoln.ac.nz/wp-content/uploads/sites/20/2020/01/lincoln.png"/>
<xsl:for-each
select="/dri:document/dri:meta/dri:pageMeta/dri:metadata[@element = 'title']">
<meta
property="og:title" content="{.}"/>
</xsl:for-each>
<xsl:for-each
select="/dri:document/dri:meta/dri:pageMeta/dri:metadata[@element =
'identifier']">
<meta
property="og:url" content="https://hdl.handle.net/{.}"/>
</xsl:for-each>
Which experiments on Twitter show works! :)
But note the image is a static logo, and I haven’t managed to get a description
in. This content doesn’t appear to be included in the dri structure – except
that dcterms.abstract is buried in the xhtml_head_item which is a giant
blob-thing of xml as text so I can’t reach into it (unless maybe I play with
substrings). Is there any other way to get at the abstract here?
And is there a way to access the mets data from page-structure.xsl? (If so, I
should be able to get the item’s thumbnail to use for the image.) We have in
item-view.xsl and I don’t see why it wouldn’t be accessible from
page-structure.xsl, but maybe that shows how much I know. In any case so far
all my trial-and-error messing around trying to access it has resulted in
errors.
Ngā mihi,
Deborah
