Now that we have a more basic answer to our original question “what is metadata”, let’s take a look at what others have had to say. Without having context, data has little reuse value. This anecdote hopefully starts to form an idea that data on the data is as important as the data itself. Not only is the object lost but even if recovered it has lost its provenance or meaning! This is why looting of archaeological sites is so damaging. If I unearth an artifact and I take it out of its context, that is, I remove it from the site, what would happen to its scientific value? That depends on how well I describe that provenance and if I use the right keywords and organizational principles that are used to categorize, describe, analyze and curate similar objects and artifacts. Provenance was the word used back then to describe the origins and the nature of objects. In 19, we had basic tcp/ip, but we did not have the array of digital tools we have today. Enrico Fermi had a lab there and the US Department of Energy saw this facility as having historical significance. It was also where the United States processed enriched Uranium for the bombs dropped on Nagasaki and Hiroshima in 1945. Hanford is the US extraction facility for weapons grade plutonium. In the early 90s, I was a (then) young archaeologist working for Battelle Pacific Northwest Laboratory on the Hanford Project. I am not that old, but I am old enough to remember doing my job without digital aids. Certainly metadata schema can be simple or complex, but they all have some things in common. The possibilities for describing things seems endless. You may have begun with a word, phrase, meme, place name, slang or something else. That search started with the metadata you had in your mind about something you wanted to find. Think about the last time you searched Google. If we use analogies, we can think of metadata as references to data. I like to answer this “what is metadata” question as such: metadata is a shorthand representation of the data to which they refer. Learn more about Metadata in this article: All you need to know about Metadata. Metadata can be created manually to be more accurate, or automatically and contain more basic information. Metadata summarizes basic information about data, making finding & working with particular instances of data easier.Data that provide information about other data.
