On Wikimedia Commons, a lot of metadata (including license and author) are not machine readable. There is an API module, iiprop=extmetadata which can be used to retrieve some values (example), but as the information is entered as free text into the file description page itself, this is not perfect. The ongoing Structured data on Commons project aims to move the metadata as fully-structured data and will eventually supersede the machine-readable data presented in this page.

In the meantime, and to ease a transition towards more structured data at a future time, Wikimedia Commons use a set of standard templates which have been made machine-readable in some ways, through HTML elements. Some scripts already make use of that. It is worth noting that this data is available for any wiki using Wikimedia Commons, where it can be read from the html of the File: page just as other local data.

Machine readable data set by infobox templates

These are several standard infobox templates tagging different elements of the template with different tags to allow parsing of the information. Several different styles of tags are used:

  • Microformat tags follow industry standards and can be parsed by already existing tools.
  • <td> id attributes (identifiers) are custom markings which allow more complete tags, which have to be read by custom tools. Most universal infoboxes have two column structure: column #1 holds name of the field and column #2 holds the value
    • Traditionally <td> id attributes were used to tag the name call in the first column in a row. To get the data, you would need to get the contents of the following <td> cell in the second column.
    • {{Creator}} and {{Institution}} templates have more complicated structure, so the cells with the actual data are tagged with attributes using magenta background.

Alternative format for CommonsMetadata

Because the table + id based format proved very hard to add to templates which were not formatted similarly to the Commons information template, CommonsMetadata allows an alternative format, similar to license templates: the whole information template has to be enclosed in a fileinfotpl class and the tag containing the specific information needs to have a fileinfotpl_* class (same names as above, but class, not id).

Introduced in October 2010, using classes <span class="licensetpl_XXX">

licensetpl
An element identifying a license. Wraps the entire license code and should be a SINGLE license, not a multi license.
licensetpl_short
Short name of the license: “Public domain”, “CC BY-SA 3.0”, “CC by 2.0 fr”, etc.
licensetpl_long
Long name of the license: “Public domain”, “Creative Commons Attribution-Share Alike 3.0”,

licensetpl_link
The link to the license deed. “www.creativecommons.org/licenses/by-sa/XXX/YYY”
licensetpl_nonfree
“true“ if this is a non-free license (not used on Commons, only on wikis with an EDP)

Multiple licensetpl blocks for the same work might be wrapped in a block using the class licensetpl_wrapper.

{{Partnership-Layout}} used by Partnership templates partnershiptemplate
{{Source-Layout}} used by generic Source templates sourcetemplate
{{Created with}} used by Created with ... templates createdwithtemplate

Machine readable data set by non-copyright restriction templates

Templates regarding non-copyright legal restrictions carry these classes to identify specific types of restrictions.

{{Trademarked}} Trademarked images restriction-trademarked
{{Copydesign}} Copyrighted designs restriction-design

{{Credit line}}
<td id="fileinfotpl_credit" class="fileinfo-paramfield fileinfotpl_credit" style=""></td>

Machine-readable data set by location templates

{{Location}} and similar templates add machine-readable geocodes in the following format: <span class="geo">12.34;24.68</span> (latitude and longitude as floating-point numbers, separated by a semicolon). The coordinates use the en:WGS84 system (same as the GPS and most online maps). See Commons:Geocoding for more details.

  • Do NOT use HTML id's, use classes. An ID can only be used once per page and most of these fields can occur multiple times per page. Consider for instance descriptions of derivative works, which can include information about the original and the derivative.
  • When possible, wrap the actual data, not some field header. This last method is historically used for all our Information templates, but much harder to support in the long run.
  • Wrap data, not the way the data is formatted.
  • Expect that formatting is lost when converting to data. Visual dress up is not part of the information.
  • Don't wrap multiple units of information inside one field. There is a difference between a publication date and a creation date. Both are dates, but both are different 'data fields'. Also CC BY-SA-4.0-3.0-2.5 is not a license name, those would be 3 licenses with the name CC BY-SA-##.
  • Make sure that the data value has one unit, or outputs one consistent unit.
