convert-records-unimarc

Convert UNIMARC bibliographic records between UNIMARC/XML, UNIMARC/JSON, and ISO 2709 binary using a local CLI powered by the Python `pymarc` package. Use this skill whenever the user asks to transform, normalize, inspect, or batch-convert UNIMARC records across XML, JSON, and MARC/ISO formats, including commands like "convert UNIMARC XML to JSON", "turn ISO 2709 into XML", or "export UNIMARC JSON as binary MARC". Prefer this skill over generic file or text-processing skills when the source material is actual UNIMARC record data. Returns JSON status summaries plus converted payloads written to stdout or a file, depending on the command options.
