In this video Africa Media Online's David Larsen, shows how to edit metadata on your MEMAT archival digital repository system. Metadata is information about information. A caption for a photograph, for instance, is metadata, as is the date of a photo captured by your digital camera. Written instructions on how to edit metadata in a MEMAT site can be found here: memat.blogs.africamediaonline.com/2009/11/08/editing-metadata/. MEMAT is a digital asset management (DAM) system that conforms closely to the ISO standard for long-term archiving of digital media.
