# 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"
  },
  "index": 8,
  "key": "_r4",
  "ref_source": "crossref",
  "release_year": 1983,
  "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.

```
{
  "biblio": {
    "unstructured": "Friedrich-Ebert-Stiftung (FES) 2008 FES in Nepal. FES http://www.fesnepal.org/about/fes_in_nepal.htm (accessed February 15, 2009)"
  },

```

Also, these may say: "accessed at ..."
