What if I only want to inherit "some" of the values in my project?
You can inherit values by clicking on the "inherit values..." box, and then un-select the box to make additional changes that are particular to that resource. For example, you can inherit the spatial information from a project to a related resource. You can then un-select the "inherit values..." box to add or subtract location keyword terms particular to that individual resource.
You can also use the project as a template for your resource entry. You can simply enable inheritance to "copy" the values from the project, and then turn inheritance off to make specific changes.
