Vera was talking to me on Wednesday about developing a short php course for
Commonists for this specific issue; namely getting and changing information
in Commons templates based on user-defined queries. On the other hand, if
all you want to do here is get the list of files that you uploaded with
that text and compare it to the list of files you want to upload in the
next batch, then probably the catscan tool that Magnus created will do the
trick:
The files have "<!--
<metadata_mapped_json>" and then the json-data, in
their file description, there the field "gwtoolset-url-to-the-media-file"
seems to be perfect. Thus if you can get the full text-page corresponding
to the file it must be possible to easily parse the text to get this part
and store it as json?
How to get the wikitext's I do not know exactly (but that seems quite
trivial).

Subject: Re: [Glamtools] Getting metadata back from Wikimedia Commons
We dont have great support for this. The best i know of is the "credit"
field in
https://commons.wikimedia.org/w/api.php?generator=categorymembers&gcmti…
<https://commons.wikimedia.org/w/api.php?generator=categorymembers&gcmtitle=%20category:%20Media%20from%20Open%20Beelden%20%20&prop=imageinfo&gcmtype=file&iiprop=extmetadata%7csha1&action=query&formatversion=2&gcmlimit=max&format=json>
but might need to parse some html (unless the data is included in exif/xmp
in which case there is a different api query you can use). Also keep in
mind you have to use the continue parameter to get the next page of results.
Hope that helps,

Hi everyone,
We’re trying to get a clearer picture of what material we have on
Wikimedia
Commons so that our next batch upload doesn’t duplicate with
material that is already on Commons. The category: Media from Open Beelden
contains all the files and we would like to have all the metadata on
Commons for that category (specifically the 'source' URL) to match against
our new content upload.
Does anyone know how to gather this using the Commons API? Basically, a
call to
the API with the “File:title” field that would return a JSON object
with all the metadata is exactly what we need. Help would be much
appreciated!
Best,
Jesse
