What do all of these attributes mean?
![]() Screenshots Download Mailing Lists | Descriptions for what some EA meanGeneral informationThe below tables do not take into account all EA for the system. They are designed as a guide to the libferris 1.1.40+ EA. Once an EA is in the system it rarely changes so these tables should be suitable for future versions of libferris. Some EA generated from libextractor, native kernel EA and RDF sources are impossible to fully enumerate here in a timely manner. Also when you mount a relational database or XML file/database attributes are created to export information of interest. For example a relational database when mounted shows its rows as files and its columns as EA on those files. One should keep this in mind and consider the tables as a reference to only some of the EAs in the system. Another section that is only briefly mentioned is the emblem EAs. This is because each user is expected to have their own emblem collection with their own partial ordering over their emblems. See the ADCS03 paper in the papers section of the site for a starting guide to emblems and one of their considered uses. The EAs everyone should be aware ofThis table describes important EA.
Native file:// EAsThis table describes various EA which are likely to be only found for file:// URLs. For file:// URLs there is also a "dontfollow-" prefixed version of some EA which present the values found from a lstat(2) call. By default the stat(2) call values are shown which means that the EA values for link files are for the link target not the link itself.
Image related EAsThese will be likely available for many image formats depending on what support for images your build of libferris was created with. Note that some EAs such as the EXIF and XMP generated EAs are not described here but have similar names to the attributes of the underlying specification where spaces and underscores are replaced with "-".
Audio related EAsThese will be available on some or all of your audio files providing interesting metadata about them.
Video related EAsThese will be available on some or all of your video files providing interesting metadata about them.
EA which relate to branch filesystemsBranch filesystems present information about a file via a virtual filesystem. For example for a digitally signed file the people who have signed the file, when they signed it and if the signature is valid are all expressed via a branch filesystem.
RPM EAThese EAs are available on RPM based Linux distributions. They provide information about each file that is taken from the rpm database on the machine. See rpm(8) for more information.
Miscellaneous EA which are very handy for specific use casesThese have been added to the system over time usually to solve specific problems.
