    I regularly use Adobe Photoshop to add and edit info associated with historical images that I have found over the years on the internet.

    I typically add add notes to the description field
    with back ground info about the image, where I found it.

    This only works with jpeg format. When I have tried with other formats such as png or tiff or gif that data is lost when image is saved and later reopened. I may save a two versions of an image such as highest resolution tiff and jpeg,

    To edit metadata in Adobe Photoshop (I am still on version CS2) select File then File Info on an open image. That brings up a dialog window which makes the rest easy. Some image viewer programs let you click and see image metatdata by looking at its properties.

    Web pages have meta data stored in the html code. You can typically select an option to show code associated with any web page to see meta tags. This is the meta data in this web page.

    In astronomy which I do quite a bit with comets and asteroids, or any other field of interest, you can create templates of meta tags for embedding image data. In the astronomy community they typically use an image or file type called .fits which stores all kinds of meta data about the image as it is processed. Fits can be used to store tables of scientific data. It is extensive.. All the NASA data is stored like this and is available to anyone on their data nodes such as their PDS: Small Body Node http://pds-smallbodies.astro.umd.edu/

    I’ve had luck with comparing metadata to the information that used to be put onto the cards in a library’s card catalog. Now, of course, that works best for folks who are old enough to remember what a card catalog is!

    Another example, I have used is to talk about the attributes of a sports card collection. The idea that you could sort and retrieve the card you want by searching for the manufacturer, e.g. Topps; or the sport, e.g. baseball or basketball; the athlete’s name, etc.

    Or another one I’ve found to be helpful is to show them a website like Zappos where you can search by and limit your search based on a variety of different attributs, such as size, style, or color. I explain that each of those attributes could be considered to be the metadata for those shoes.

    Thank you for your comments!

    I appreciate hearing about the ways in which different communities, like NASA, store their data. Using popular consumer sites to provide examples of metadata is another great suggestion, to which I think everyone can relate.
