DB2RIS(1)			  RefDB Manual			       DB2RIS(1)

NAME
     db2ris - converts DocBook bibliographic data to the RIS format

SYNOPSIS
     db2ris  [-a]  [-e log-destination]  [-h]  [-L log-file] [-o file] [-O file]
	    [-r reftype] file

DESCRIPTION
     db2ris converts DocBook bibliographic data into RIS files. The  design  and
     purpose  of  the DocBook bibliography information is too different from the
     RIS format to warrant a simple and straightforward conversion, let alone  a
     bi-directional one. The DocBook bibliography definition allows for a lot of
     freedom  how  to encode your information. To accommodate as wide a range of
     uses and abuses of the bibliographic elements as possible, this import fil-
     ter is implemented as a DSSSL stylesheet rather than as  a  C  application.
     This  allows  you to quickly change or extend the stylesheet to adapt it to
     your needs. db2ris is a wrapper script which invokes OpenJade to do the ac-
     tual transformation.

OPTIONS
     -a
	Use full first- and othernames	if  they  are  present	in  the  DocBook
	source. By default, all first- and othernames will be abbreviated.

     -e log-destination
	log-destination  can  have  the  values  0,  1,  or 2, or the equivalent
	strings stderr, syslog, or  file,  respectively.  This	value  specifies
	where the log information goes to.  0 (zero) means the messages are sent
	to stderr. They are immediately available on the screen but they may in-
	terfere  with  command output.	1 will send the output to the syslog fa-
	cility. Keep in mind that syslog must be configured to accept  log  mes-
	sages  from user programs, see the syslog(8) man page for further infor-
	mation.   Unix-like   systems	usually   save	 these	  messages    in
	/var/log/user.log.   2 will send the messages to a custom log file which
	can be specified with the -L option.

     -h
	Displays help and usage screen, then exits.

     -L log-file
	Specify the full path to a log file that will receive the log  messages.
	Typically this would be /var/log/refdba.

     -o file
	Send  output  to file instead of to stdout. If file exists, its contents
	will be overwritten.

     -O file
	Send output to file instead of to stdout. If  file  exists,  the  output
	will be appended.

     -r reftype
	Set  the  default  RIS	reference type. This type will be used if db2ris
	cannot infer the reference type from the BiblioEntry element.

     file
	The names of one or more DocBook files.

CONFIGURATION
     db2ris evaluates the file db2risrc to initialize itself.

DATA PROCESSING
     We have to make a bunch of assumptions to arrive at a suitable output:

     *	db2ris	will  handle  only  "raw" (as opposed to "cooked") bibliographic
	data. This basically means that you must encode all  bibliographic  data
	in BiblioEntry elements, not in BiblioMixed elements.

     *	db2ris discards all publication date information from the PubDate except
	the  first  4  characters of #PCDATA so these should better be a 4-digit
	year.

     *	By default, the publication type is neither explicitly encoded in a Bib-
	lioEntry element nor can it be easily inferred. Therefore db2ris assumes
	that the BiblioEntry carry a role attribute  with  the	RIS  publication
	type  as  the value. If the attribute is missing, a default type is used
	instead. This means that you should add these attributes before the con-
	version in order to get useful RIS datasets (or fix the  TY  entries  in
	the RIS file afterwards).

     *	DocBook  does not have a special element to encode the name of a journal
	or magazine that published an article. Instead the same Title element is
	used as for the article title, a book title, or a series title. To  dis-
	tinguish between a journal or magazine name and "real" titles, the Title
	element encoding the journal name is assumed to be nested in a BiblioSet
	whose relation attribute is set to "journal", "pub", "abbrev", or "full"
	(this  more or less arbitrary list can of course be extended or changed,
	see below). The values "abbrev" and "full"  furthermore  decide  whether
	the RIS tag "JO" or "JF" will be used.

MODIFYING DB2RIS
     As  previously stated, db2ris is implemented as a DSSSL stylesheet that can
     be easily and quickly adapted to your needs. It may be  prudent  to  create
     copies of the script and modify these in order to adapt them for particular
     "abuses" of the DocBook bibliographic elements in various documents or data
     sources.  This  section  briefly  lists  the functions which you would most
     likely want to change.

     reftype-heuristic
	This function attempts to infer the correct RIS publication type.

     titletype-heuristic
	This function gives a hint whether a Title element is used  as	a  jour-
	nal/magazine name or as an article title or book title.

     process-date
	This function creates a valid string for the RIS PY tag from the PubDate
	element.

FILES
     /usr/local/etc/refdb/db2risrc
	The global configuration file of db2ris.

     $HOME/.db2risrc
	The user configuration file of db2ris.
