-Availability:
+  * **2.01**: Many of the UDF standard's ambiguities were resolved in this version.
+  * **2.50**: Metadata Partition facilitating metadata clustering,easier crash recovery and optional duplication of file system information:

-I do not know yet if I have enough time for realization write support, but I will start working in this direction and and finish after %%GSoC%%.
+  * **May 21 - May 24**: transferring implementation UDF from %%NetBSD%% into %%FreeBSD%% source code and consider libraries used in the project (''%%ecma167-udf.h%%'', ''%%osta.h%%'', ''%%udf.h%%'', ''%%udf_mount.h%%'') what structures, flags and  parameters of main functions are used.
+  * **May 25 - June 10**: modify function ''%%udf_mount%%'', ''%%udf_mountfs%%'', ''%%udf_unmount%%'' and others for mount new type of disc in file ''%%udf_vfsops.c%%''.
+  * **June 11 - July 24**: modify function ''%%udf_access%%'', ''%%udf_getattr%%'', ''%%udf_open%%'', ''%%udf_pathconf%%'', ''%%udf_readdir%%'', add ''%%udf_advloc%%'', ''%%udf_close%%'' and others in file ''%%udf_vnops.c%%''
+  * **June 25 - June 1**: making appropriate changes in ''%%udf_osta.c%%''
+  * **June 1 - June 16**: add new key to maintenance command ''%%mount_udf%%'' for support new version of UDF, test and fix bugs in previous functional.
+  * **July 16 - July 29**: Adaptation ''%%udf_allocation%%'' to implement directory hashing to speed up directory traversals in mounted devices.
+  * **July 30 - August 5**: add new options to ''%%mount_udf(8)%%'' for example:
-Deliverables:
+<code>
+-u uid      Set the owner of anonymous files on the file system.  The
+              default owner is the user nobody.
+-t gmtoff   Set the time zone offset (in seconds) from UTC to gmtoff,
+              with positive values indicating east of the Prime Meridian.
+              If not set, the user's current time zone will be used.
+-g gid      Set the group of anonymous files on the file system.  The

-May 21 - May 24 -- transferring implementation UDF from %%NetBSD%% into %%FreeBSD%% source code and consider libraries used in the project (ecma167-udf.h, osta.h, udf.h, udf_mount.h) what structures, flags and  parameters of main functions are used.
+  * **August 6 - August 12**: final test all parts of code.
-May 25 - June 10 -- modify function udf_mount,  udf_mountfs, udf_unmoun and others for mount new type of disc in file udf_vfsops.c.
+  * **August 13 - August 20**: write all documentation for implemented udf functional.
-June 11 - July 24 -- modify function udf_access, udf_getattr, udf_open,  udf_pathconf, udf_readdir, add udf_advloc, udf_close and others in file udf_vnops.c
-June 25 - June 1 -- making appropriate changes in udf_osta.c
-June 1 - June 16 -- add new key to maintenance command mount_udf for support new version of UDF, test and fix bugs in previous fuctional.
-July 16 - July 29 -- Adaptation udf_allocation to implement directory hashing to speed up directory traversals in mounted devices.
-July 30 - August 5 -- add new options to mount_udf(8) for example:
--u uid      Set the owner of anonymous files on the file system.  The
-default owner is the user nobody.
--t gmtoff   Set the time zone offset (in seconds) from UTC to gmtoff,

-For testing my code I will mount different type of discs, various DVD-Video and DVD-ROM disks, also CD-R, CD-RW, CD-MRW, DVD-RW, DVD+RW, DVD+MRW,  Blu-ray Disc,(USB) flash media and harddisc partitions.      Also compare the speed of operation with support directories hashing using the timer.
