There are really two ways to go about learning how to create metadata. One is to attend a metadata training workshop. Check the Metadata Training Calendar to see if a training workshop is being offered in your area or the Metadata Trainers Registry to contact a trainer in your area about offering a workshop. The other is to learn how to develop metadata on your own. Below you will find some guidelines to help you get started with your metadata development.
Metadata development is more than storing text in a cryptic format.
Strategies must be developed and techniques implement to create metadata. Examining how others document their data sets may provide insight to the most appropriate strategy for you. Choosing the right tool is an important decision. There are numerous collection and management tools out there. These surveys provide basic information on a number of publicly available and commercial tools.
