-====== Barcode Processing ======
-When a barcode is scanned in TapeTrack it is sent to the Server component to be interpreted and split (or parsed) into its respective components.
-===== Barcode Syntax Rules =====
-A TapeTrack Barcode may be up to 20 characters in length and may contain a [[Customer-ID]] and [[Media-ID]] component and must contain at least a [[Volume-ID]] component.
-==== Parsing Logic ====
-The TapeTrack Server parses barcodes as follows:
-The unparsed barcode will be looked up in the [[Barcode Translation Table]] and if it is found the translated barcode will be substituted.
-When a corresponding [[TapeMaster Barcode Interpretation Definitions | Barcode Interpretation Definition]] is found the barcode is split into [[Customer-ID]], [[Media-ID]] and [[Volume-ID]] components.
-If the [[Customer-ID]] and [[Media-ID]] components are not resolved then the [[Default Customer-ID#Scanned|Scanned Default Customer-ID]] and [[Default Media-ID#Scanned|Scanned Default Media-ID]] values (if any) are used to set the [[Customer-ID]] and [[Media-ID]].
-#If the [[Customer-ID]] and [[Media-ID]] components are not resolved then the [[TapeMaster Creating Users | User Profile Default Customer-ID]] and [[TapeMaster Creating Users |User Profile Default Media-ID]] values (if any) are used to set the [[Customer-ID]] and [[Media-ID]].
-#If the [[Media-ID]] component remains unresloved and the [[TapeMaster Creating Customers | Customer Properties]] has the ''No-Duplicate Volume-ID'' attribute set then the server will attempt to find the [[Media-ID]] for the unique [[Volume-ID]] if the [[Volume-ID]] exists.
-#Using the [[Customer-ID]] and [[Media-ID]] values the [[Media Properties]] are looked up.
-#If the [[TapeMaster Creating Media Types | Media Properties]] has the ''Remove Volume-ID Suffix'' value set and there is a matching suffix the suffix is removed.
-#If the [[TapeMaster Creating Media Types | Media Properties]] have the Modulo 43 option '''AND''' there is no corresponding length exclusion all except the last digit of the component [[Volume-ID]] are processed through the Modulo 43 algorithm.
-#If the last digit of the [[Volume-ID]] does not match the calculated Modulo 43 value a barcode scanning error is returned.
-#If the last digit of the [[Volume-ID]] does match the calculated Modulo 43 value the barcode is returned with the [[Volume-ID]] component stripped of it's check digit.
-=Additional Logic for Batch Programs=
-Batch programs that parse barcodes will also check for the existence of the environment variable {{EnvVariable|TMSS10BARCODECONFIG}} when the program starts.
-This variable is used to define the path to a config file containing settings that influence how barcode is performed.
-<pre class="brush:plain">
-set TMSS10BARCODECONFIG=c:\tmss\etc\barcode.cfg
-TMSS10ValidateBarcode
-</pre>
-==Example Batch Barcode Config File==
-<pre class="brush:c">
-defaults =
-{
-    customer-id = "ACME";
-    media-id = "DL";
-};
-</pre>
-==Programs that load the Barcode Config File==

-*[[TMSS10Inventory]]
-*[[TMSS10ValidateBarcode]]
