'''Metadata''' is extra non-critical information about the main contents of a file, or about the circumstances in which a file was created, etc.

Many, many formats contain data that could be considered to be metadata, but this page is only concerned with dedicated metadata formats which, for one reason or another, are best documented as separate formats.

Metadata is a great thing to have for publicly-available files, but there's a sinister side to it too... it's come out lately that all sorts of people are snooping into the metadata of your life (such as who you're calling or e-mailing), and this can reveal a lot about you.

Articles about individual metadata '''elements''' are usually listed in [[Elements of File Formats]], instead of here.

Property List

The '''Property List''' (plist) file is a standard feature of the operating systems descended from NeXTSTEP, which includes the current Apple operating systems. It is the standard way for programs developed under such systems to save and load data between the internal representation within the objects defined in an [[Objective-C]] program and disk files, in order to store program settings and other data. The Cocoa framework's standard objects have built-in methods to deal with these files. NeXTSTEP had a text-based format for this, in a style resembling a programming language; Apple replaced it with an [[XML]]-based format for Mac OS X, and later on they also introduced a binary format as well, which is now the default save format for preference files.

Several variations:

* [[Property List/NeXTSTEP|NeXTSTEP Property Lists]]
* [[Property List/XML|XML Property Lists]]
* [[Property List/Binary|Binary Property Lists]]

Current MacOs development frameworks can also use property lists in [[JSON]], but these can't necessarily be precisely transferred to and from the other formats, since the data types aren't exactly the same.
