metadata element="identifier" qualifier="handle" is missing in pageMeta or DRI

[euler]

Dear All,

I wonder, if I view the DRI of an item, there is no metadata element="identifier" qualifier="handle" in the DRI or //dri:meta/dri:pageMeta/dri:metadata. I asked because I created a variable name identifier_handle in the global-variables.xsl which will be used by Altmetrics template in item-view.xsl.

    <!-- item metadata reference -->

    <xsl:variable name='identifier_doi'

                  select='//dri:meta/dri:pageMeta/dri:metadata[@element="citation_doi"]'/>

    <xsl:variable name='identifier_handle'

                  select='//dri:meta/dri:pageMeta/dri:metadata[@element="identifier" and @qualifier="handle"]'/>

Below is a snippet of my altmetrics template where the variable identifier_handle is called:

                <xsl:choose>    <!-- data-doi data-handle data-arxiv-id data-pmid -->

                    <xsl:when test='$identifier_doi'>

                        <xsl:attribute name='data-doi'><xsl:value-of select='$identifier_doi'/></xsl:attribute>

                    </xsl:when>

                    <xsl:when test='$identifier_handle'>

                        <xsl:attribute name='data-handle'><xsl:value-of select='$identifier_handle'/></xsl:attribute>

                    </xsl:when>

                </xsl:choose>

Since there is no value for identifier_handle because it is missing in dri:pageMeta/dri:metadata, the Altmetrics badge is not shown. Altmetrics is shown for items with doi by the way since it is present in pageMeta.

My question now is how can I make the handle appear in pageMeta and what file should I modify? I am using DSpace version 6.3 Mirage2. I did not edit any *.java files in this repository, since when I tried to look where pageMeta was generated, I assumed that it is generated by ItemViewer.java (please correct me if I'm wrong) which I did not modify.

In other repositories that I am working on (with almost the exact customizations), the handle is there in pageMeta.

Thanks in advance!

Dear All,

I tried rebuilding using mvn -U clean package but I still don't see the '<metadata element="identifier" qualifier="handle">' in the DRI document under the //dri:meta/dri:pageMeta/dri:metadata structure.

Please help on how I could resolve this.

Thank you so much in advance!

Hello,

in the 'dri:pageMeta' you will only find information about the displayed document, not about the item's metadata (cf. https://wiki.lyrasis.org/display/DSDOC6x/DRI+Schema+Reference#DRISchemaReference-pageMeta)

In 'item-view.xsl' you can directly select metadata values from the 'dim:field' of item's metadata mets.xml ([dspace-url]/metadata/handle/[...]/mets.xml). Take a look at the xsl:templates used there.

I hope this helps and kind regards,

Paul Münch

Dear All,

I would like to reiterate my query about why there is no metadata element="identifier" qualifier="handle" in the pageMeta of my items. I got a response from Paul, thanks Paul but it did not address why it is missing. I am aware that I can select metadata values from the 'dim:field' of the item's metadata mets.xml. What I would really like to know is why it is missing and how to make the metadata element="identifier" qualifier="handle" appear in the pageMeta. I assumed that this is supposed to exist because it is being referenced in the global-variables.xsl in Mirage theme.

Even in my local instance using the default 6.3 version without any customizations, it is still missing. I looked for many repositories of others to see if the element="identifier" qualifier="handle" is also missing and I found an example here: https://iris.paho.org/DRI/handle/10665.2/52154 although it is using the 6.4-SNAPSHOT version.

If anybody could shed light on this and how to resolve and what to look for would be really appreciated.

Thanks in advance!

Well, I can't specifically answer your question, but I can verify that this element exists in v5.10 in the <pageMeta>!

I will add that it is also present in v5.5 and v6.3 but on Mirage (don't know about Mirage2).
