This loader will always create a bib record
One item record is created for each 949 1 control field

Match on “o” index

o index includes 001 and 019.

Code:

/^999||t|0|20| | |0|n|G|0|#com="ov"@ov_tag="o"

0 matches: Insert new bib
1 match: Overlay existing bib
2 matches: Insert new bib

Code:

|||0|0| | |0|n|G|0|@ov_action="o"

Variable (retain both incoming and target data)

Field group: h LIB HAS
Field group: k TOC DATA
- MARC tags: 970, 971
Field group: m LOAD NOTE
- MARC tags: 995
Field group: n NOTE
- MARC tags: 583
Field group: y MISC
- MARC tags: 948, 958

Variable (retain only target data, ignore incoming data)

Field group: v LOCAL INFO
- MARC tags: 590, 690, 691, 856 (only if target field contains “|2pika”)

SPEC’L USE

Code:

@ov_protect="b=V0123456789hk(970,971)m(995)n(583)v(590,69.,856:d)y(948,958)F31"

Bib: tabeb

Item: tapei

These are the default templates in Marmot loaders. The template settings only take effect if that field is not defined in any other way by the record load.

Code:

/^999||o|0|20| | |0|n|G|0|#com="dflt"@dflt="tapeb,tapei"

These commands will override defaults in the bib record. This is rarely used.

recs = Load profile
bn = bib location
ct = Cat Date
b1 = Bib Lvl
b2 = Mat Type
b3 = Spec’l Use
la = Language
cy = Country

Format:

949 \\$a*recs=b;bn=cu;ct=01-18-2021;b1=m;b2=a;b3=w;la=spa;cy=cou;

Code:

/^999||z|0|10| | |0|n|G|0|#com="recs"@recs="b"
/^999||a|0|30|b| |26|n|N|0|#com="bn"
/^999||c|0|8|b| |28|n|N|0|#com="ct"
/^999||d|0|1|b| |29|n|N|0|#com="b1"
/^999||e|0|1|b| |30|n|N|0|#com="b2"
/^999||f|0|1|b| |31|n|N|0|#com="b3"
/^999||g|0|3|b| |24|n|N|0|#com="la"
/^999||k|0|3|b| |89|n|N|0|#com="cy"

This will always set the CAT DATE to today.

Code:

|||0|0| | |0|n|G|0|@cdate="y"

Processed by m2bmap.sky translation map.

This translation map removes OCLC prefixes from 001 field. Other prefixes are left in place. SkyRiver prefix is left in place.

If there is only a number with no prefix, the word “prefix” is added as a prefix.

Code:

001||%|0|0|b|o|0|y|N|0|%map="m2bmap.sky"

m2bmap.sky:

@case=true
@stop_on_map=true
^(001)$0ocl70*([1-9][0-9]*)$1|\0\1
^(001)$0ocm0*([1-9][0-9]*)$1|\0\1
^(001)$0ocn([1-9][0-9]*)$1|\0\1
^(001)$0on([1-9][0-9]*)$1|\0\1
^(001)$0( *[a-zA-Z].*)$1|\0\1
^(001)$0(.*)$1|\0prefix\1

If the target record is in field group v LOCAL INFO and includes any of these strings:

|2pika
|2vufind
|2image
|2Pika
|2VuFind
|2Image

then the field is protected. No incoming 856 field with “|2pika” will load in that case.

All other 856 fields are not protected. They will be overlaid from the incoming record. If there is no 856 in the incoming record, they will be deleted from the target record.

Code:

856||+|0|0|b|v|0|y|N|0|%map="m2bmap.art"
