tl;dr
Enable access to the extra
property of pages in the sitemap.xml template.
Full version
As the documentation says we get only permalink
and date
for a page. The sitemaps protocol defines a field called lastmod
. This should be set to the date the page was last modified. Currently zola just set this field to the date
of the post. This is in many cases not the same as the date.
Example: You post something in an blog. The publishing date is the date
-field of this blog entry. 7 days later you update some details on this blogpost. The date
will stay the same but lastmod
should be updated.
I tried to do this by add an extra field into my content and adapted the sitemap.xml like this
1 {% for page in pages %}
2 <url>
3 <loc>{{ page.permalink | safe }}</loc>
4 {% if page.extra.lastmod %}
5 <lastmod>{{ page.extra.lastmod }}</lastmod>
6 {% elif page.date %}
7 <lastmod>{{ page.date }}</lastmod>
8 {% endif %}
9 </url>
10 {% endfor %}
but as we do not have access to the extra
-context in this template this will not work.
So i suggest to enable access to the extra
-content in this template.
