Bug ID: 71690
Summary: MMV: Viewer displays strange "YYYY:MM:DD" colon
separated format
Product: MediaWiki extensions
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: MultimediaViewer
Assignee: [email protected]
Reporter: [email protected]

Web browser: ---
Mobile Platform: ---
Example:
http://commons.wikimedia.org/wiki/File:Pelican_in_its_piety.jpg#mediaviewer/File:Pelican_in_its_piety.jpg
The viewer shows "Created: 2006:03:19 10:29:45"
I'm not sure what that format is supposed to be, but it looks like an error.
Afaik no human readable standard uses that format. It certainly doesn't seem
like something we'd do on purpose (based on a MediaWiki Language or Moment.js
format), which is enough for it to be an error from the user's perspective.
Looking at the regular file page, it seems MediaWiki has no problem parsing
this Metadata:
Date and time of data generation
10:29, 19 March 2006
So seems fair to expect MMV to handle this as well.
Simple Commons gadgets have never had this issue. A simple extraction of the
'.exif-datetimeoriginal' node in #mw_metadata would be a step forward (instead
of the imageinfo API and trying to parse it). Since that's already parsed an
localised server-side. Scraping is ugly, but parsing should make it better.
The value is exposed via the imageinfo API:
http://commons.wikimedia.org/w/api.php?action=query&format=json&prop=imageinfo&titles=File%3APelican_in_its_piety%2Ejpg&iiprop=timestamp%7Cuser%7Curl%7Csize%7Cmime%7Cmediatype%7Cextmetadata&iiextmetadatafilter=DateTime%7CDateTimeOriginal%7CImageDescription%7CLicense%7CLicenseShortName%7CUsageTerms%7CLicenseUrl%7CCredit%7CArtist%7CGPSLatitude%7CGPSLongitude%7CPermission&iiextmetadatalanguage=en
"extmetadata": {
"DateTime": {
"value": "2006:03:19 10:29:45",
"source": "file-metadata",
"hidden": ""
},
"ImageDescription": {
"value": "KONICA MINOLTA DIGITAL CAMERA",
"source": "file-metadata"
},
"DateTimeOriginal": {
"value": "2006:03:19 10:29:45",
"source": "file-metadata"
}
},

Bug seems to originate from
https://github.com/wikimedia/mediawiki-extensions-MultimediaViewer/blob/c86b2bba26726f2c36c340eeff7afd8d7a1c0df4/resources/mmv/ui/mmv.ui.metadataPanel.js#L672-L693
where it attempts to have Moment.js parse this format. Which it can't.
Momment.js has, however, a built-in capability to parse custom formats by
passing the format as the second argument:
> moment('2006:03:19 10:29:45')
< Invalid date
> moment('2006:03:19 10:29:45', 'YYYY:M:D H:m:s')
< "Sun Mar 19 2006 10:29:45"
If this colon-separated format is how all Image metadata is stored by camera's,
I'd say just parse it by telling moment.js the format.
