does anyone recognize this MARC JSON format?

VladimirAlexiev commented 6 years ago

Hello Catmandu MARC experts! I'm turning to you in despair... Does anyone recognize this format (see paste at bottom)? It's from Répertoire de vedettes-matière (RVM). It's neither of these two:

I can hack it with just XS::JSON but I don't know how to deal with this weird accent encoding (a few sample lines shown from 325):

{grave}e
{ring}Z
{ringb}h
{ringb}s
{rlig}a
{rlig}A

Here's the strange MARC JSON:

{
"rows" : [
{
    "RecordNumber" : "1",
    "Tag" : "LDR",
    "Indicators" : "",
    "Content" : "00533nz   2200205n  4500"

Hi, this is a strange JSON serialization of the MARCMaker format: https://www.loc.gov/marc/mnemonics.html

MARCMaker looks like the record below and has these "Mnemonic Strings" {ring} etc
