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"

}
```

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.
