# description: this program takes file(s) written in XML following
# the DTD used in the LoC MARC XML. For each record found,
# the program decides whether it is an upload or a
# correction (sysno existence, report number existence).
# Then each field is created or corrected.
# The process is based on three classes: record, field and
# subfield.

Uploads xml records in the bibliographical database.
Bibupload first tries to match the xml record with an existing one.
o If the match succeeds and an update mode is selected, the matched record
is updated
o If the match succeeds and no update mode is selected, an error occurs
o If the match fails and an insert mode is selected, the record is added as new
o If the match fails and no insert mode is selected, an error occurs
Options:
-h, --help print this help
-V, --version print version information
-u, --user choose user
-v, --verbose verbosity level (0=mute, 1=default info msg,
2=display record analysis, 3=display integration requests,
9=max information)
-n, --notimechange
do not change record last modification date when updating
-b, --brieffmtupdate
force brief format recreation at next reformatting
(sets bibfmt hb last_update to 1970)
-t, --time sets date/time of execution (format 'yyyy-mm-dd hh:mm:ss')
INSERT Mode
-i, --insertrecord unmatched records are added as new.
this can be mixed with -r.
UPDATE Modes:
-r, --replacerecord the existing record is entirely replaced by the new one
-a, --appendfield new fields are appended to the existing record
-c, --correctfield fields are replaced by the new ones in the existing
record
-f, --format takes only the FMT fields into account. Does not update
the modification stamp either.
-z, --ref update references (update only 999 fields and check 037 field
against both 037 and 088.)
Example:
./bibupload -t '2004-10-24 05:00' -i toto.xml\n");
