1 00:00:00,957 --> 00:00:02,895 Cos'è CommonsDB?

2 00:00:03,603 --> 00:00:07,980 Simply put, it is a registry for public domain and openly licensed works.

3 00:00:08,092 --> 00:00:11,972 With it you can look up if an image is known to be in the public domain.

4 00:00:12,541 --> 00:00:14,293 Come funziona?

5 00:00:15,515 --> 00:00:20,038 CommonsDb uses a system built upon the International Standard Content Code,

6 00:00:21,072 --> 00:00:24,568 che è anche uno ISO-standard, ISO 24138.

7 00:00:25,875 --> 00:00:30,354 Questo significa che a code is generated by feeding the image to an algorithm.

8 00:00:31,908 --> 00:00:35,413 The code is then stored in the registry, along with some metadata.

9 00:00:37,343 --> 00:00:41,773 Any other image can be compared to all the codes that are in the registry.

10 00:00:44,385 --> 00:00:47,163 Thanks to the cleverness of the algorithm,

11 00:00:47,163 --> 00:00:50,346 the comparison can tell how similar the images are,

12 00:00:51,067 --> 00:00:55,417 and it is resistant to scaling and compression artifacts.

13 00:00:57,871 --> 00:00:59,586 Come può essere usato?

14 00:01:00,358 --> 00:01:04,396 The obvious usage would be to check if a new image is in the registry.

15 00:01:05,092 --> 00:01:07,770 If it is, we are sure that we can use it,

16 00:01:08,868 --> 00:01:12,132 and that could possibly even select the right license template.

17 00:01:13,517 --> 00:01:17,351 But there are also many other things these codes enables on the media

18 00:01:17,383 --> 00:01:20,305 già su Wikimedia Commons.

19 00:01:20,597 --> 00:01:26,817 Per esempio, we could see if media has conflicting copyright claims compared to the registry,

20 00:01:26,817 --> 00:01:30,461 meaning that someone selected the wrong license template during the upload.

21 00:01:32,611 --> 00:01:38,092 Or, we could find various kind of duplicates when we see that images are similar.

22 00:01:39,132 --> 00:01:42,303 Some are rightfully so, like restorations,

23 00:01:42,893 --> 00:01:46,052 but there may also be involuntary ones.

24 00:01:46,516 --> 00:01:51,191 Finding them can help the community decide if they should be deleted,

25 00:01:51,191 --> 00:01:54,549 kept or perhaps get the categories improved.

26 00:01:55,900 --> 00:01:58,099 The registry is being built,

27 00:01:58,190 --> 00:02:01,034 but how we as a Wikimedia community would like to use it

28 00:02:01,034 --> 00:02:03,852 and how it should be integrated is still up for discussion.

29 00:02:04,943 --> 00:02:07,166 What would be most useful to you?

30 00:02:07,166 --> 00:02:09,814 Let us know at this page on Meta.
