 Can we create video ids also different for different shows?
 ==Answer==
-Yes, but again not with built-in components of iNEWS. The idea behind this solution is the same as for the single video id script (see ). You need a combination of a Linux shell script and a macro inside iNEWS.
+Yes, but again not with built-in components of iNEWS. The idea behind this solution is the same as for the single video id script (see [[forum:inews:video-ids]]).
-  - The shell script is started via crontab once a day very early morning. It generates a list of new video-ids (for that day) in a hidden place of the iNEWS database.
-  - The macro moves the next entry out of this list and paste it into the video-id field of the current story. An already assigned video id will not be overwritten by the macro.
+:!: There are two strict limitations so far:
+  * You have to create stories for different rundowns in separate folders. It is not possible to choose the relevant show during the video id assignment.
+  * Name((Strictly spoken the last part of a queue name - i.e. show.1800.**rundown**)) of queues where video ids are assigned in must have exactly a given length. Otherwise the macro will fail. The given macros below assume a queue name with seven characters like ''rundown''.
+At all you need a combination of a Linux shell script and a macro inside iNEWS.
+  - The shell script is started via crontab once a day very early morning. It generates multiple lists of new video-ids (for that day) in hidden places inside the show directories.
+  - The macro moves the next entry out of the relating list and paste it into the video-id field of the current story. An already assigned video id will not be overwritten by the macro.
 So this solution take care about:
   - The video id is unique. Whenever a user picks up a video id out of the list this id is immediately removed from the list. No chance to take the same id twice.
   - The video id for a given story is fix. The macro keeps an already assigned id in the target story. It's not possible to change the id after working with (at least not with our macro)
+  - The video id contains a show-specific string
+The specification which shows will get what video ids in what format with what special string is to setup inside the iNEWS system directory.
+  - The video id has finally the format ''<show string><date>-<sequence number>''. The show string and date format are configurable. The sequence number runs from 001 up to 999.
 == Setup ==
-  - Video-id queue - inside iNEWS Client
+  - Management story - inside iNEWS Client as superuser
-    * Create a new folder ''hidden'' in iNEWS database.
+    * Create a queue inside the system directory, usually SYSTEM.RUNDOWNS
+    * Place one story inside this queue which contains the description of each rundown or folder where video ids for a given show have to be assigned. If there are more than one story in this queue all stories are processed.
+    * All empty lines and strings after semicolon (;) are ignored. Also the program proofs the format of the remaining lines and only valid ones are taken.
+    * The format of each line is<code>
+<rundown> <show string> <date format></code>
+      * The ''<rundown>'' is the queue where video ids are assigned. Its parent folder must contain a hidden folder with a video-id queue inside. See next point how to create it.
+      * The ''<show string>'' is a string containing only characters A-Z, a-z and 0-9 and especially it must contain no spaces.
+      * The ''<date format>'' refers to the linux strftime format. Call ''man strftime'' on the iNEWS server console to get more help.
+      * Here is a sample story for description of some rundowns:<code>
+; This story must contain the list of all rundown queues.
+; It is used by the linux script /site/scripts/video-ids/video-ids.sh.
+; All rundowns must be named "RUNDOWN".
+; There must be a HIDDEN.VIDEO-IDS queue in each show directory.
+; Format of the entries is:
+; <rundown>			<show string>	<date format>
+news.1800.rundown	 	N18		%d%m%y
+news.2130.rundown		N21		%d%m%y
+features.business.rundown	FB		%d%m%y</code>
+  - Video-id queues - inside iNEWS Client
+    * Create a new folder ''hidden'' in each show directory (see previous point) inside iNEWS database.
     * Inside create a new queue ''video-ids''.
     * Set readgroup for the folder to ''nobody''.
     * Set readgroup **and** writegroup for the queue to ''!none'' or the group which is allowed to assign video-ids.
     * Set the queue to inverted.
   - Script - Linux shell as user root (su) on **both** machines - inews-a and inews-b, respectively.
     * Create a directory ''/site/scripts/video-ids''

     * Test the macro. Save the keyboard story. Choose this keyboard in your preferences. Then go to a rundown story and press the related shortcut. If the story have had no video-id, now it should have the next one out of your list (and this number should be removed from the list). If the story have had a video-id before, this video-id should be there even if you run the macro. In that case nevertheless a number is removed from the list.
 == Comments ==
-  * The script above creates video-ids in the format ''ddmm-xxx''whereas ''xxx'' is a sequential number. This format can be easily changed or extended.
-  * Actually the script produces 300 ids. Of course you can increase this value by adjusting the loop border.
