35 * @short_description: Key-Value Paired File Attributes
36 * @see_also: #GFile, #GFileInfo
38 * File attributes in GIO consist of a list of key-value pairs.
40 * Keys are strings that contain a key namespace and a key name, separated
41 * by a colon, e.g. "namespace:keyname". Namespaces are included to sort
42 * key-value pairs by namespaces for relevance. Keys can be searched
43 * for using wildcards, e.g. "std:*" will return all of the keys in the
46 * Values are stored within the list in #GFileAttributeValue structures.
47 * Values can store different types, listed in the enum #GFileAttributeType.
48 * Upon creation of a #GFileAttributeValue, the type will be set to
49 * %G_FILE_ATTRIBUTE_TYPE_INVALID.
51 * The Key-value list is stored within the #GFile structure as a
52 * #GFileAttributeInfoList. This list is queryable by key names
53 * as indicated earlier.
55 * Classes that implement #GFileIface will create a #GFileAttributeInfoList and
56 * install default keys and values for their given file system, architecture,
57 * and other possible implementation details (e.g., on a UNIX system, a file
58 * attribute key will be registered for the user id for a given file). Other
59 * attributes can be appended to a #GFileAttributeList later by
60 * g_file_attribute_info_list_add().
64 * <title>GFileAttributes Namespaces</title>
65 * <tgroup cols='2' align='left'><thead>
66 * <row><entry>Namspace</entry><entry>Description</entry></row>
69 * <row><entry>"std"</entry><entry>The "Standard" namespace. General file
70 * information that any application may need should be put in this namespace. Examples
71 * include the file's name, type, and size.</entry></row>
72 * <row><entry>"etag"</entry><entry>The "Entity Tag" namespace.
73 * GIO use "entity tags" to quickly determine if a file has been modified
74 * from the version on the file system. Entity tags are globally unique identifiers,
75 * and should always be sent with the current revision of a file.
76 * An example of a key in this namespace is "value", which contains the value of the
77 * current entity tag.</entry></row>
78 * <row><entry>"id"</entry><entry>The "Identification" namespace. This
79 * namespace is used by file managers and applications that list directories
80 * to check for loops and to uniquely identify files.</entry></row>
81 * <row><entry>"access"</entry><entry>The "Access" namespace. Used to check
82 * if a user has the proper privilidges to access files and perform
83 * file operations. Keys in this namespace are made to be generic
84 * and easily understood, e.g. the "can_read" key is %TRUE if
85 * the current user has permission to read the file. UNIX permissions and
86 * NTFS ACLs in Windows should be mapped to these values.</entry></row>
87 * <row><entry>"mountable"</entry><entry>The "Mountable" namespace. Includes
88 * simple boolean keys for checking if a file or path supports mount operations, e.g.
89 * mount, unmount, eject.</entry></row>
90 * <row><entry>"time"</entry><entry>The "Time" namespace. Includes file
91 * access, changed, created times. </entry></row>
92 * <row><entry>"unix"</entry><entry>The "Unix" namespace. Includes UNIX-specific
93 * information and may not be available for all files. Examples include
94 * the UNIX "UID", "GID", etc.</entry></row>
95 * <row><entry>"dos"</entry><entry>The "DOS" namespace. Includes DOS-specific
96 * information and may not be available for all files. Examples include
97 * "is_system" for checking if a file is marked as a system file, and "is_archive"
98 * for checking if a file is marked as an archive file.</entry></row>
99 * <row><entry>"owner"</entry><entry>The "Owner" namespace. Includes information
100 * about who owns a file. May not be available for all file systems. Examples include
101 * "user" for getting the user name of the file owner.</entry></row>
102 * <row><entry>"thumbnail"</entry><entry>The "Thumbnail" namespace. Includes
103 * information about file thumbnails and their location within the file system. Exaples of
104 * keys in this namespace include "path" to get the location of a thumbnail, and "failed"
105 * to check if thumbnailing failed.</entry></row>
106 * <row><entry>"fs"</entry><entry>The "Filesystem" namespace. Gets information
107 * about the file system where a file is located, such as its type, how much
108 * space is left available, and the overall size of the file system.</entry></row>
109 * <row><entry>"gvfs"</entry><entry>The "GVFS" namespace. Keys in this namespace
110 * contain information about the current GVFS backend in use. </entry></row>
116 * More namespaces can be added from GIO modules or by individual applications.
117 * For more information about writing GIO modules, see #GIOModule.
