Total storage space of the filesystem, which can be different from nie:contentSize because the latter includes filesystem format overhead.
Unoccupied storage space of the filesystem.
Occupied storage space of the filesystem.
Universally unique identifier of the filesystem. In the future, this property may have its parent changed to a more generic class.

Stream position of the bookmark, suitable for e.g. audio books. Expressed in milliseconds
An address specifying a remote host and port. Such an address can be interpreted in many ways (examples of such interpretations include mailboxes, websites, remote calendars or filesystems), depending on an interpretation, various kinds of data may be extracted from such an address.
A file attached to another data object. Many data formats allow for attachments: emails, vcards, ical events, id3 and exif...
A file embedded in another data object. There are many ways in which a file may be embedded in another one. Use this class directly only in cases if none of the subclasses gives a better description of your case.
The amount of characters in the document.
States that a piece of software supercedes another piece of software.
A piece of software. Examples may include applications and the operating system. This interpretation most commonly applies to SoftwareItems.
Indicates the name of the programming language this source code file is written in. Examples might include 'C', 'C++', 'Java' etc.
An image of a filesystem. Instances of this class may include CD images, DVD images or hard disk partition images created by various pieces of software (e.g. Norton Ghost). Deprecated in favor of nfo:Filesystem.
A common superproperty for all properties signifying the amount of bits for an atomic unit of data. Examples of subproperties may include bitsPerSample and bitsPerPixel
A HTML document, may contain links to other files.
Number of Low Frequency Expansion (subwoofer) channels.
Connects a media container with a single media stream contained within.

States if a given resource is password-protected.
Uncompressed size of the content of a compressed file.
A compressed file. May contain other files or folder inside.
A file entity that has been deleted from the original source. Usually such entities are stored within various kinds of 'Trash' or 'Recycle Bin' folders.
A MindMap, created by a mind-mapping utility. Examples might include FreeMind or mind mapper.
A service published by a piece of software, either by an operating system or an application. Examples of such services may include calendar, addressbook and mailbox managed by a PIM application. This category is introduced to distinguish between data available directly from the applications (Via some Interprocess Communication Mechanisms) and data available from files on a disk. In either case both DataObjects would receive a similar interpretation (e.g. a Mailbox) and wouldn't differ on the content level.
The original location of the deleted resource.
A website, usually a container for remote resources, that may be interpreted as HTMLDocuments, images or other types of content.
This property is intended to point to an RDF list of MediaFiles.
A file containing a list of media files.e.g. a playlist
A single node in the list of media files contained within an MediaList instance. This class is intended to provide a type all those links have. In valid NRL untyped resources cannot be linked. There are no properties defined for this class but the application may expect rdf:first and rdf:last links. The former points to the DataObject instance, interpreted as Media the latter points at another MediaFileListEntr. At the end of the list there is a link to rdf:nil.
A folder with bookmarks of a webbrowser. Use nfo:containsBookmark to relate Bookmarks. Folders can contain subfolders, use containsBookmarkFolder to relate them.
Amount of bits used to express the color of each pixel.
The average overall bitrate of a media container. (i.e. the size of the piece of media in bits, divided by it's duration expressed in seconds).
