00:00We've talked a bit about metadata, but just maybe you could walk us through for the students.
00:05What is metadata and why is it important?
00:08Well, metadata is really simply data about data.
00:13And so that's the easiest way, I think, to think about it.
00:17In a traditional library, metadata is often the biggest bunch of metadata is the catalog,
00:25the description of the holdings of the library.
00:28And so these are ways in which we try to assist the user in discovering what's in the collection
00:35by having those descriptive cues, the title, the author, the date of publication,
00:41and then subject headings being another form of metadata that allows us to look for things
00:47even if we don't know what titles are available.
00:50So in a digital world, every time we build a group, a database of images, for example,
00:57you can't search those images, you can't find anything of use unless you have a way
01:02to grab them that is searchable.
01:06And that's changing over time as we find new ways with artificial intelligence
01:11and other computational forms to study color and other kinds of search methods.
01:17But at the end of the day, most search through images is based on how someone described it
01:24in a text form using metadata.
