# V4

Have not release v3, but many change to `skate` so we may continue with v4.

# Unstructured

```
{
  "biblio": {
    "unstructured": "J. Häger, W. Krieger, T. Rüegg, and H. Walther, J. Chem. Phys. 72, 4286 (1980).JCPSA60021-9606"

  "release_ident": "tebzylkszzbyjggye5ssmebdcy",
  "work_ident": "aaaofyp6uzcdnbe7hvfahylyha"
}
```

We should be able to match: "J. Chem. Phys.", also maybe "72, 4286 (1980)", w/
id, title we should be able to match to:
https://fatcat.wiki/release/d2k7en7tzzdzzddwfo5xlqx4ce

If nothing else defined, and unstructured contains a URL, we may extract that.

However, there is no explicit "subtitle" fields, and in this case, the subtitle is buried in "text":

```

    "The debt",
    "The Debt",
