Metadata may not be the most exciting thing in the GIS world, but it is one of the most important. Without properly documented metadata, datasets – and the analysis that occurs on them – are practically useless. It’s essential to know the source and intended uses of all data being used in a GIS analysis. In short, it’s crucial to know your data.
In ArcGIS 10, metadata workflows have changed quite a bit compared to previous versions. For more information regarding metadata in ArcGIS 10, see “A New Approach for Metadata with ArcGIS 10 Part 1, Part 2 and Part 3.”
One of the most common questions we get in support is: “How do I know what to put in the metadata?” The answer depends on a number of things, most notably, what type of metadata is being created. The type of metadata created depends on what metadata style is specified in the ArcCatalog Options dialog. See the help here for more information on how to set the metadata style.
A simple way to determine what you need to enter when you’re authoring metadata is to look at what’s displayed in the context help at the bottom of the ArcCatalog window. For instance, as shown below, when the cursor is placed under Description in the Item Description section of metadata created using the North American Profile of ISO 19115 2003, the context help will produce a message that indicates what type of information is expected.
The above message outlined in red indicates that information included in the Description of the metadata should be similar to information included in an abstract.
In some cases, the Context Tip may not offer enough guidance. That’s when it’s time to refer to published content standards. These content standards are a wealth of information regarding what can be included in metadata. All content standards, including FGDC, North American Profile of ISO and INSPIRE are available on the Web.

I have used metadata (9.3.1 format) for a number of years now, but am really struggling to figure out the terminology in the new tools. It seems all the terms have changed and bear little resemblance to what the standards (FGDC at least) are asking for. If I want to put in information about a source document, where does it go? What is a Feature Catalogue? It seems that in order to create FGDC metadata, I must study the ISO standard to understand how the two relate. That seems a bit unrealistic.
