comments in template files

[floriangantner]

Is your feature request related to a problem? Please describe.
In template files for ReferCrosswwalk (e.g. cerif https://github.com/4Science/DSpace/blob/main-cris/dspace/config/crosswalks/template/project-cerif-xml.template ) there is currently no possibility to make comments. Comments might be necessary for questionable xml Elements or more information about the semantic for elements, for example in cerif xml the version of the openaire guidelines where some element was introduced.

Describe the solution you'd like
We would like some support for single line comment in template lines. This might by any line starting with # and trimmed by whitespaces.

When parsing the file in

DSpace/dspace-api/src/main/java/org/dspace/content/integration/crosswalks/ReferCrosswalk.java

Line 245 in 0dc31d5

private TemplateLine buildTemplateLine(String templateLine) {

, the lines might be first checked for the comment sign and if so skipped and not be added to the templatelines

Describe alternatives or workarounds you've considered

• make comments in git issues or other tracking systems
