Auto generated number in Dspace

[Amit Gupta]

Hi All,

For one of our clients we have created the item type - Conference Proceedings, as per the custom fields defined by the client.

The client is seeking a self-generated sequence number for a custom field called 'control number', with the following format: MyRepository/current date/CP/01

Example values for this will be as follows:

MyRepository/23-Jun-2019/CP/01

MyRepository/24-Jun-2019/CP/01

MyRepository/24-Jun-2019/CP/02

Is this possible in DSpace?

Regards,

Amit

AFAIK not out-of-the-box.
Generally spoken, you can use a modified template in the XMLUI and fetch
a number from a service in the background.
Or use Javascript in the web site (security !).

But you need a service (program) to generate the numbers and to keep
track of them (database, e.g.).

this depends  - first, you need to use XMLUI e.g., second, you need to
develop a REST-service which accesses a database (you need your own
tables, DSpace alone will not be sufficient).

This needs a developer, so.
If you want to use that field during submit, you need a template to
replace DSpace's code by your own code like so:

  <xsl:template
match="//dri:field[@id='aspect.submission.StepTransformer.field.dc_yourfield']">
<br/>
  <input type="text">
         <xsl:attribute name="readonly">readonly</xsl:attribute>
         <xsl:attribute
name="id">aspect_submission_StepTransformer_field_dc_yourfield</xsl:attribute>
         <xsl:attribute name="name">dc_identifier</xsl:attribute>
         <xsl:choose>
         <xsl:when test="not(.//dri:value)">
                 <xsl:attribute name="value">
                         <xsl:apply-templates
select="document('THE_URL_TO_YOUR_SERVICE')"/>
                 </xsl:attribute>
         </xsl:when>
         <xsl:otherwise>
                 <xsl:attribute name="value"><xsl:value-of
select=".//dri:value"/></xsl:attribute>
         </xsl:otherwise>
         </xsl:choose>
  </input>
  <br/>
  </xsl:template>

This mus be placed in a file below your theme, e.g.
*/xmlui/Mirage2/xsl/core/ (make your own dir for your company).

Depending on your needs, the code for the service can be several hundred
lines.
Be sure to know what you do !
