245__0$a

Reference to value of the subfield "a" of the first three repetitions of field "307" within the context of indicator 1 with the value "8". This will NOT reference the first three 307 fields that are in the context of indicator 1.

Reference to contextualized data with subSpecs examples

###Checking dependencies via string comparison

If Leader/06 = t: Books

Reference to character with position "18" of field "008", if character with position "06" in Leader equals "t".

008/18{LDR/6=\t}

If Field 007/00 = a and t

Reference to subfield "b" of field 245, if character with position "0" of field 007 equals "a" OR "t".

245$b{007/0=\a|007/0=\t}

If Leader/06 = a and Leader/07 = a, c, d, or m: Books

Reference to character with position "18" of field "008", if character with position "06" in Leader equals "a" AND character with position "07" in Leader equals "a", "c", "d" OR "m".

008/18{LDR/6=\a}{LDR/7=\a|LDR/7=\c|LDR/7=\d|LDR/7=\m}

Example data:

100 1#$6880-01$aZilbershtain, Yitshak ben David Yosef.
880 1#$6100-01/(2/r$a, יצחק יוסף בן דוד.

Reference data content of subfield "a" of field "880", if data content of subfield "6" of field "100" includes the string "-01" (characters with index range 3-5 of field "800") and the string "880".

880$a{100_1$6~$6/3-5}{100_1$6~\880}

###Checking existence of fields

Reference data content of subfield "c" of field "020", if subfield "a" of field "020" exists.

020$c{$a}

Reference data content of subfield "z" of field "020", if subfield "a" of field "020" does not exist.

020$z{!$a}

###Abbreviation of fieldSpec or subfieldSpec

As of [MARCspec interpretation] a MARCspec without an explicitly given index is always an abbreviations of n references this example shows how these specs are interpreted.

Example Data:

020 ##$a0394170660$qRandom House$c$4.95
020 ##$a0491001304

Reference to data content of subfield "q" of field "020" if subfield "c" exists.

020$q{$c}

same as

020[0-#]$q[0-#]{$c[0-#]}

same as

020[0]$q[0]{?020[0]$c[0]} OR // true
020[1]$q[0]{?020[1]$c[0]} // false

Example Data:

020 ##$a0394170660$qRandom House$qpaperback$c$4.95
020 ##$a0394502884$qRandom House$qhardcover$c$12.50

Reference to data content of subfield "c" if data content of one repetition of subfield "q" equals the comparison string "paperback".

020$c{$q=\paperback}

same as

020[0-#]$c[0-#]{$q[0-#]=\paperback}

same as

020[0]$c[0]{020[0]$q[0]=\paperback} OR // false
020[0]$c[0]{020[0]$q[1]=\paperback} OR // true
020[1]$c[0]{020[1]$q[0]=\paperback} OR // false
020[1]$c[0]{020[1]$q[1]=\paperback}    // false

Reference to data of the first repetition of field "800", if data content of subfield "a" within the context of indicator 2 is "1" of the preceding fieldSpec includes the comparisonString "Poe".

800[0]{800[0]__1$a~\Poe}

An abbreviated subTerm like __1$a in

800[0]{__1$a~\Poe}

is invalid! An abbreviated subterm MUST only be one of fieldspec or subfieldspec.

Reference of data content of subfield "a" of field "245", if last character of the preceding spec equals the comparisonString "/".

245$a{/#=\/}

same as

245$a{245$a/#=\/}
