For current drawing classified DWGs

For a classified DWG (page 2057) used as the current drawing, the metadata is

stored inside the DWG. Because the DWG file stores the location of the data

source, the metadata will be updated (page ?) with each data update, or each

time it connects to updated data.

When you export metadata from a current classified DWG, it is transferred to

an MTD file. Although the file has an .mtd extension, its format is XML. A

linking file is also created and placed in the same location as the MTD file. If

the following conditions are met, the linking file retains the location of the

data, and the exported metadata are kept current.

■ The MTD file and the linking file are kept together

■ The data source remains in the same location

■ Auto update is selected in the

Metadata Options dialog box (page 1756)

For non-DWG files and feature classes

An MTD file is also generated when you create metadata for a non-DWG file

or a feature class (which is one type of resource (page 2072)).

When you export metadata for a feature class, a feature source definition (FSD)

file is created in addition to the MTD. In this case, it is the FSD file that keeps

the metadata linked to its source data.
