Standardized Metadata Elements

The following table describes the standardized metadata elements that File Content Extraction can create.

NOTE: Accessed, created, and modified dates are retrieved from values stored within the document, and are typically set by the creating application. For documents that exist on disk, this may differ from what the operating system reports - for example, if the document was moved or copied.

NOTE: Raster image documents (for example TIFF files) can contain multiple images, so File Content Extraction outputs metadata for the primary image.
