Metadata

The Metadata object provides metadata information about a file or folder (metadata are things like the track number of a music file, the dimensions of an image, the author of a document, etc). You can obtain a Metadata object from the Item.metadata property if you have an Item object, and if not you can obtain it using the path of the item using the FSUtil.GetMetadata method.

The Metadata object provides different sub-objects as properties that group the available metadata into a number of categories, broadly corresponding to the categories listed on the Keywords for Columns page. You can determine the primary, or main type of metadata available using the default value of the Metadata object.

Property Name	Return Type	Description
<default value>	string	Returns a string indicating the primary type of metadata available in this object. The string will be one of the following: none, video, audio, image, font, exe, doc, other. Note that sometimes more than one type of metadata will be available. For example, author is a document field (and so found under the doc property), but pictures can have authors as well. In this instance, the Metadata object would provide both ImageMeta and DocMeta objects. If the returned string is none it means that no metadata is available for the file, and you should not attempt to access any of the other properties.
audio	object:AudioMeta	Returns an AudioMeta object providing access to audio metadata. The properties of this object are generally returned as their appropriate underlying type (e.g. a numeric field like "track number" will be returned as an int).
audio_text	object:AudioMeta	Returns an AudioMeta object that provides access to the unmodified text form of the audio metadata. This provides access to the same text as displayed in a Lister. For example, a numeric field like "track number" would be returned as a string rather than an int.
doc	object:DocMeta	Returns a DocMeta object providing access to document metadata.
doc_text	object:DocMeta	Returns a DocMeta object that provides access to the unmodified text form of the document metadata.
exe	object:ExeMeta	Returns an ExeMeta object providing access to executable (program) metadata.
exe_text	object:ExeMeta	Returns an ExeMeta object that provides access to the unmodified text form of the program metadata.
font	object:FontMeta	Returns a FontMeta object providing access to font file metadata.
image	object:ImageMeta	Returns an ImageMeta object providing access to picture metadata.
image_text	object:ImageMeta	Returns an ImageMeta object that provides access to the unmodified text form of the picture metadata.
other	object:OtherMeta	Returns an OtherMeta object that provides access to miscellaneous metadata.
tags	collection:string	Returns a collection of strings corresponding to the tags that are assigned to this item.
video	object:VideoMeta	Returns a VideoMeta object providing access to video metadata.
video_text	object:VideoMeta	Returns a VideoMeta object that provides access to the unmodified text form of the video metadata.
