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 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.
Type of compression. Instances of this class represent the limited set of values allowed for the nfo:compressionType property.
An Icon (regardless of whether it's a raster or a vector icon. A resource representing an icon could have two types (Icon and Raster, or Icon and Vector) if required.
A HTML document, may contain links to other files.
A piece of software. Examples may include applications and the operating system. This interpretation most commonly applies to SoftwareItems.
A file containing a list of media files.e.g. a playlist
A resource containing a finite sequence of bytes with arbitrary information, that is available to a computer program and is usually based on some kind of durable storage. A file is durable in the sense that it remains available for programs to use after the current program has finished.
A folder/directory. Examples of folders include folders on a filesystem and message folders in a mailbox.
A filesystem. Examples of filesystems include hard disk partitions, removable media, but also images thereof stored in files.
A service published by a piece of software, either by an operating system or an application. Examples of such services may include calendar, addresbook 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.
A DataObject representing a piece of software. Examples of interpretations of a SoftwareItem include an Application and an OperatingSystem.
A Presentation made by some presentation software (Corel Presentations, OpenOffice Impress, MS Powerpoint etc.)
A file data object stored at a remote location. Don't confuse this class with a RemotePortAddress. This one applies to a particular resource, RemotePortAddress applies to an address, that can have various interpretations.
A file containing a text document, that is unambiguously divided into pages. Examples might include PDF, DOC, PS, DVI etc.
A superclass for all entities, whose primary purpose is to serve as containers for other data object. They usually don't have any "meaning" by themselves. Examples include folders, archives and optical disc images.
A spreadsheet, created by a spreadsheet application. Examples might include Gnumeric, OpenOffice Calc or MS Excel.
Represents a container for deleted files, a feature common in modern operating systems.
A fingerprint of the file, generated by some hashing function.
Code in a compilable or interpreted programming language.
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.
A file attached to another data object. Many data formats allow for attachments: emails, vcards, ical events, id3 and exif...
A compressed file. May contain other files or folder inside.
A MindMap, created by a mind-mapping utility. Examples might include FreeMind or mind mapper.
A stream of multimedia content, usually contained within a media container such as a movie (containing both audio and video) or a DVD (possibly containing many streams of audio and video). Most common interpretations for such a DataObject include Audio and Video.
A folder with bookmarks of a webbrowser. Use nfo:containsBookmark to relate Bookmarks. Folders can contain subfolders, use containsBookmarkFolder to relate them.
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)
A generic document. A common superclass for all documents on the desktop.
A bookmark of a webbrowser. Use nie:title for the name/label, nie:contentCreated to represent the date when the user added the bookmark, and nie:contentLastModified for modifications. nfo:bookmarks to store the link.
A file containing plain text (ASCII, Unicode or other encodings). Examples may include TXT, HTML, XML, program source code etc.
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 website, usually a container for remote resources, that may be interpreted as HTMLDocuments, images or other types of content.
A piece of media content. This class may be used to express complex media containers with many streams of various media content (both aural and visual).
The amount of character in comments i.e. characters ignored by the compiler/interpreter.
Number of channels. This property is to be used directly if no detailed information is necessary. Otherwise use more detailed subproperties.
Models the containment relations between Files and Folders (or CompressedFiles).
Visual content aspect ratio. (Width divided by Height)
The size of the file in bytes. For compressed files it means the size of the packed file, not of the contents. For folders it means the aggregated size of all contained files and folders
States that a piece of software is in conflict with another piece of software.
Indicates the name of the programming language this source code file is written in. Examples might include 'C', 'C++', 'Java' etc.
Name of a class defined in the source code file.
True if the image is interlaced, false if not.
A string containing the permissions of a file. A feature common in many UNIX-like operating systems.
A common superproperty for all properties signifying the amount of atomic media data units. Examples of subproperties may include sampleCount and frameCount.
Number of Low Frequency Expansion (subwoofer) channels.
States that a piece of software supercedes another piece of software.
A name of a function/method defined in the given source code file.
This property is intended to point to an RDF list of MediaFiles.
Name of the algorithm used to compute the hash value. Examples might include CRC32, MD5, SHA, TTH etc.
Name of the file, together with the extension
The encoding used for the Embedded File. Examples might include BASE64 or UUEncode
Vertical resolution of an Image (if printed). Expressed in DPI
Name of a global variable defined within the source code file.
The type of the compression. Values include, 'lossy' and 'lossless'.
Connects a media container with a single media stream contained within.
URL of the file. It points at the location of the file. In cases where creating a simple file:// or http:// URL for a file is difficult (e.g. for files inside compressed archives) the applications are encouraged to use conventions defined by Apache Commons VFS Project at http://jakarta.apache.org/ commons/ vfs/ filesystems.html.
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
The owner of the file as defined by the file system access rights feature.
A common superproperty for all properties specifying the media rate. Examples of subproperties may include frameRate for video and sampleRate for audio. This property is expressed in units per second.
The name of the codec necessary to decode a piece of media.
The original location of the deleted resource.
The foundry, the organization that created the font.
Amount of bits used to express the color of each pixel.
The amount of frames in a video sequence.
Horizontal resolution of an image (if printed). Expressed in DPI.
The amount of characters in the document.
The type of the bitrate. Examples may include CBR and VBR.
States if a given resource is password-protected.
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).
The address of the linked object. Usually a web URI.
Uncompressed size of the content of a compressed file.
