NAME

       wlmscpfs - DICOM Basic Worklist Management SCP (based on data files)

SYNOPSIS

       wlmscpfs [options] port

DESCRIPTION

       The  wlmscpfs application implements a Service Class Provider (SCP) for the Basic Worklist
       Management Service. The application will listen on a specified TCP/IP  port  for  incoming
       association  requests  from  a  Worklist  Management  SCU.  In  case  an  association  was
       acknowledged and a worklist query  was  received,  the  wlmscpfs  application  will  query
       particular  files  in  a  certain  directory (which can be specified through corresponding
       program options) on the file system for corresponding worklist information,  and  it  will
       send this information back to the calling Worklist Management SCU. Aside from dealing with
       Worklist Management queries, the  wlmscpfs  application  also  supports  the  Verification
       Service Class as an SCP.

NOTES

       The  semantic impacts of the above mentioned options is clear for the majority of options.
       Some particular options, however, are so specific that  they  need  detailed  descriptions
       which will be given in this passage.

       The  returned  character  set  options  are  intended for situations in which the wlmscpfs
       application will return attribute values which are not composed  of  characters  from  the
       DICOM  default character repertoire. In such cases, for example option --return-iso-ir-100
       can be used to specify that a response to a modality's worklist management C-FIND  request
       shall  contain  DICOM's  Specific Character Set attribute (0008,0005) with a corresponding
       value, indicating the character repertoire from which the characters of returned attribute
       values  were  taken  (in  this  example  the  repertoire ISO IR 100). Please note that the
       wlmscpfs application will not make sure that all returned values are actually made  up  of
       this character repertoire; the application expects this to be the case.

       In  general, the Specific Character Set attribute (0008,0005) will only be included in the
       C-FIND response if it contains any attributes that are affected by the character set, i.e.
       for value representations PN, LO, LT, SH, ST and UT.

       Please note that a C-FIND request which is handled by this application may contain DICOM's
       Specific Character Set attribute (0008,0005), but this application  will  never  use  this
       attribute's  value  for  matching. Besides, the question if DICOM's Specific Character Set
       attribute (0008,0005) will be contained in a C-FIND response which  is  returned  by  this
       application  is always determined by the returned character set option which was specified
       when this application was started.

       The options --enable-file-reject and  --disable-file-reject  can  be  used  to  enable  or
       disable  a  file rejection mechanism which makes sure only complete worklist files will be
       used during the matching process. A worklist file is  considered  to  be  complete  if  it
       contains  all necessary type 1 information which the SCP might have to return to an SCU in
       a C-FIND response message. Table K.6-1 in part 4 annex K of the DICOM standard  lists  all
       corresponding type 1 attributes (see column 'Return Key Type').

   DICOM Conformance
       The wlmscpfs application supports the following SOP Classes as an SCP:

       VerificationSOPClass                  1.2.840.10008.1.1
       FINDModalityWorklistInformationModel  1.2.840.10008.5.1.4.31

       The  wlmscpfs  application will accept presentation contexts for all of the abovementioned
       supported SOP Classes using any of the transfer syntaxes:

       LittleEndianImplicitTransferSyntax    1.2.840.10008.1.2
       LittleEndianExplicitTransferSyntax    1.2.840.10008.1.2.1
       BigEndianExplicitTransferSyntax       1.2.840.10008.1.2.2

       The default behaviour of the wlmscpfs application is to prefer transfer syntaxes having an
       explicit  encoding  over  the  default implicit transfer syntax. If wlmscpfs is running on
       big-endian hardware it will  prefer  BigEndianExplicit  to  LittleEndianExplicit  transfer
       syntax  (and  vice  versa).  This  behaviour can be changed with the --prefer options (see
       above).

       The wlmscpfs application does not support extended negotiation.

       Currently, the wlmscpfs application supports the following attributes as matching keys:

       (0008,0050) AccessionNumber
       (0008,0090) ReferringPhysicianName
       (0010,0010) PatientName

       The attribute (0008,0005) SpecificCharacterSet is  a  special  case  and  its  support  by
       wlmscpfs is discussed in the NOTES section above.

   Access Control
       When compiled on Unix platforms with TCP wrapper support, host-based access control can be
       enabled with the --access-control command line option. In this  case  the  access  control
       rules  defined  in  the system's host access control tables for wlmscpfs are enforced. The
       default  locations  of  the  host  access  control   tables   are   /etc/hosts.allow   and
       /etc/hosts.deny. Further details are described in hosts_access(5).

LOGGING

       The level of logging output of the various command line tools and underlying libraries can
       be specified by the user. By default, only errors and warnings are written to the standard
       error  stream.  Using option --verbose also informational messages like processing details
       are reported. Option --debug can be used to get more details  on  the  internal  activity,
       e.g.  for  debugging  purposes.  Other  logging levels can be selected using option --log-
       level. In --quiet mode only fatal errors are reported. In such very severe  error  events,
       the  application will usually terminate. For more details on the different logging levels,
       see documentation of module 'oflog'.

       In case the logging output should be written to file (optionally with  logfile  rotation),
       to  syslog  (Unix)  or  the  event  log  (Windows)  option  --log-config can be used. This
       configuration file also allows for directing only certain messages to a particular  output
       stream  and  for  filtering certain messages based on the module or application where they
       are generated. An example configuration file is provided in <etcdir>/logger.cfg).

COMMAND LINE

       All command line tools use the following notation for parameters: square brackets  enclose
       optional  values  (0-1),  three  trailing  dots  indicate that multiple values are allowed
       (1-n), a combination of both means 0 to n values.

       Command line options are distinguished from parameters by  a  leading  '+'  or  '-'  sign,
       respectively. Usually, order and position of command line options are arbitrary (i.e. they
       can appear anywhere). However, if options are mutually exclusive the rightmost  appearance
       is used. This behaviour conforms to the standard evaluation rules of common Unix shells.

       In  addition,  one or more command files can be specified using an '@' sign as a prefix to
       the filename (e.g. @command.txt). Such a command argument is replaced by  the  content  of
       the corresponding text file (multiple whitespaces are treated as a single separator unless
       they appear between two quotation marks) prior to any further evaluation. Please note that
       a  command  file  cannot  contain another command file. This simple but effective approach
       allows to summarize common combinations  of  options/parameters  and  avoids  longish  and
       confusing command lines (an example is provided in file <datadir>/dumppat.txt).

ENVIRONMENT

       The  wlmscpfs  utility  will  attempt  to  load  DICOM  data dictionaries specified in the
       DCMDICTPATH environment variable. By default, i.e. if the DCMDICTPATH environment variable
       is  not  set,  the  file <datadir>/dicom.dic will be loaded unless the dictionary is built
       into the application (default for Windows).

       The default behaviour should be preferred and the DCMDICTPATH  environment  variable  only
       used when alternative data dictionaries are required. The DCMDICTPATH environment variable
       has the same format as the Unix shell PATH  variable  in  that  a  colon  (':')  separates
       entries. On Windows systems, a semicolon (';') is used as a separator. The data dictionary
       code will attempt to load each file specified in the DCMDICTPATH environment variable.  It
       is an error if no data dictionary can be loaded.
