CommonsMetadata should retrieve custom Credit Line through licensetpl_attr
Closed, ResolvedPublic

Description

On Wikimedia Commons, users may indicate how they wish to be attributed through two specific mechanisms.

One is the {{Credit line}} template − see for example [1]

The other one is the attribution parameter of license templates − see for example [2]

As documented in [3], the attribution line in the second mechanism is marked with a <span class='licensetpl_attr'> − the first one is not but I just made a proposal for it to be.

This information should be retrieved by CommonsMetadata.

bzimport set Reference to bz57460.

The license template part will be covered by the pending patch in bug 57197.
{{Information}} fragments have their own mechanism, see the section about infobox templates on [[Commons:Machine-readable data]]. I think it would be better to follow that, and keep the licensetpl_* stuff for actual license templates.

{{Credit line}} already uses a fileinfotpl_credit attribute, except it is a class, not an id. I think the cleanest solution would be to change that to an id, and document it in [[Commons:Machine-readable data]].

Also, licensetpl_* fields will probably be handled in a more complex way due to the possibility of multilicensing - most clients will probably want to show a single license only, so we will try select the least restrictive one and ignore attributes not belonging to that. "Global", license-independent attributes should better not use that mechanism. (Although this is just speculation at this point, there is no proper handling of multiple licenses currently - that is bug 57259.)

Huh, well, not sure what I was supposed to do but whatever. Attribution specified through {{Credit line}} is now wrapped in a class="licensetpl_attr".

The current implementation of CommonsMetadata ignores licensetpl_* fields not wrapped in a licensetpl class, so this won't have any effect. As I said, adding it to the information template metadata syntax seems like a more logical solution to me.

I know. I was merely trying to make a stab at harmonizing Commons various, « inconsistent » ways of specifying attribution. If that’s not useful, well, *shrug*.

Scrap that, I misread your comment. Well, *shrug*² then.

Again, how about adding id="fileinfotpl_credit" (to the first column, not the second) instead of class="fileinfotpl_credit"? That would be at least consistent with how other {{Information}} fields are marked, and trivial to parse.
