perhaps you should also have a look how the new GVFS handles setting and 
reading file attributes. it seems to have a quite flexible model of 
"named" attributes (with namespaces)...

gfileinfo.h:

/* Calculated Access Rights for current user */

#define G_FILE_ATTRIBUTE_ACCESS_READ "access:read"               /* 
boolean */
#define G_FILE_ATTRIBUTE_ACCESS_WRITE "access:write"             /* 
boolean */
#define G_FILE_ATTRIBUTE_ACCESS_EXECUTE "access:execute"         /* 
boolean */
#define G_FILE_ATTRIBUTE_ACCESS_DELETE "access:delete"           /* 
boolean */
#define G_FILE_ATTRIBUTE_ACCESS_RENAME "access:rename"           /* 
boolean */

[...]

/* Unix specific attributes */

#define G_FILE_ATTRIBUTE_UNIX_DEVICE "unix:device"               /* 
uint32 */
#define G_FILE_ATTRIBUTE_UNIX_INODE "unix:inode"                 /* 
uint64 */
#define G_FILE_ATTRIBUTE_UNIX_MODE "unix:mode"                   /* 
uint32 */
#define G_FILE_ATTRIBUTE_UNIX_NLINK "unix:nlink"                 /* 
uint32 */
#define G_FILE_ATTRIBUTE_UNIX_UID "unix:uid"                     /* 
uint32 */
#define G_FILE_ATTRIBUTE_UNIX_GID "unix:gid"                     /* 
uint32 */
#define G_FILE_ATTRIBUTE_UNIX_RDEV "unix:rdev"                   /* 
uint32 */
#define G_FILE_ATTRIBUTE_UNIX_BLOCK_SIZE "unix:block_size"       /* 
uint32 */
#define G_FILE_ATTRIBUTE_UNIX_BLOCKS "unix:blocks"               /* 
uint64 */

[...]

/* Owner attributes */

#define G_FILE_ATTRIBUTE_OWNER_USER "owner:user"                 /* 
string */
#define G_FILE_ATTRIBUTE_OWNER_GROUP "owner:group"               /* 
string */


from gfile.h :
