Prefetch Service prefetches no longer ONLINE available studies from an external archive or attached NEARLINE storage on receive of a HL7 Order Message (ORM^O01) for the patient.
Therefore Stylesheet is used to create a C-FIND Request from the received HL7 message which is sent to source and destination AET. The results are used to get a list of series that are available on source but not on destination.
The PostSelectStylesheet can be used for further, more detailed selection and/or to specify the schedule time of the C-MOVE request. ]]> org.dcm4chex.archive.hl7.PrefetchService The default constructor PrefetchService archive-install-directory/server/default/.]]> Stylesheet java.lang.String OnlyKnownSeries boolean A relative path name is resolved relative to archive-install-directory/server/default/.
Use NONE to disable post selection (use the 'notAvailable' list gathered from C-FIND responses instead)
This stylesheet should create a 'schedule' tag for each series that should be prefetched: <schedule seriesIUID='...' [scheduleAt='yyyyMMddHHmmss.SSS'] [reason='some reason'] />
The 'input' xml format:
<prefetch>
 <hl7> ... <hl7>
 <dataset> ... <dataset>
 ...
</prefetch> ]]> PostSelectStylesheet java.lang.String LogPostSelectXML boolean Format:
