1.4.8 Processes
1.4.8.1 Metadata file
Each process typically includes a metadata file together with the transferred images. It is also possible to just
send metadata.
When defining a process that sends metadata, the administrator can define the metadata file content and
structure, such as the filename and extension. Macros can be used in both cases, if desired.
Default content for the metadata file is an xml structure displaying a summary of the last scan process
execution, total number of pages, and a list of generated filenames.
Additional metadata tags provide an example which indicates the device IP and hostname.
<?xml version=”1.0”?>
<metadata xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance
”
xmlns:xsd=”http://www.w3.org/2001/XMLSchema” version=”1.0”>
<jobInfo>
<timeStamp>%_Process.Timestamp_%</timeStamp>
<pageCount>%_Scan.ScanNumPages_%</pageCount>
<files count=”%_Process.FileCount_%”>
<WHILE type=”id” scope=”last” delimiter=””>
<filename>%_Process.FileNames_%</filename>
</WHILE>
</files>
<item type=”string”>
<tag>ip_address</tag>
<value>%_Device.Devicelp_%</value>
</item>
<item type=”string”>
<tag>hostname</tag>
<value>%_Device.DeviceHostName_%</value>
</item>
</jobInfo>
</metadata>
1.4.8.2 Retries
Some processes allow retries, and a retry time interval while defining them.
If a process cannot be completed due to network or destination failure, it will retry the transfer after the retry
time interval until it works, or until the amount of retries is exhausted.
Unlimited retries can be defined. If there is a long network failure, all scanned document files will remain on
the device until connectivity is recovered.
If retries are unlimited, and the destination is no longer available, files will remain on the device forever, or
until an administrator removes them by an API call.
Parameter behavior is as follows:
●
MaxNumRetries (Integer / optional) — The number of times the job should attempt to be sent when
there is an error in sending. If set to -1, no retries are attempted. If set to 0, retries are tried infinitely. If
this value is not set to 1, retries will be set as the default.
●
RetryInterval (Integer / optional) — The interval in seconds between retries. If this value is not set,
the interval will default to 10 seconds.
