A MARC record is just a 'record' key in a JSON document which contains an ARRAY of ARRAY values. All the fixes copy_field, move_field, etc etc can operate on each type of JSON document. A copy of a MARC field could be implemented with something like:<br> </div> <div><br> </div> <div> <div># Copy the 100 field to 400</div> <div>do list(path:record, var:c)</div> <div> if all_match(c.0,100)</div> <div> copy_field(c,copy.$append)</div> <div> replace_all(copy.$end.0,100,400)</div> <div> end</div> <div>end</div> <div><br> </div> <div>move_field(copy.*,record.$append)<br> </div> <div>remove_field(copy)<br> </div> <br> </div> <div>This is ARRAY processing without knowing this ARRAY is MARC. What Catmandu::MARC does is hiding a lot of this array processing and provide a much simpler MARCPath and MARCSpec syntax. Alas, the marc_copy_field is not something implemented yet in this easier syntax, but <span style="font-size: 12pt;">I've made a ticket for </span><span style="font-size: 12pt;">that: </span><a href="https://github.com/LibreCat/Catmandu-MARC/issues/76" style="font-size: 12pt;">https://github.com/LibreCat/Catmandu-MARC/issues/76</a></div> <div><br> </div> <div><span style="font-size: 12pt;">3) marc_add</span><br> </div> <div><span style="font-size: 12pt;"><br> </span></div> <div><span style="font-size: 12pt;">The marc_add could be used to add data to a new MARC record ..but I see this option doesn't work anymore.
