# 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.

```

}
```

* https://openlibrary.org/works/OL488811W/The_debt?edition=debtwhatamerica000robi

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

```

  "text": [
    "/works/OL488811W",
    "The debt",
    "The Debt",

## OL Loop

Some do not have an explicit "works" key, but still link to an edition.

## Unmatched

If we exclude any id and title, we'll roughly have the following fields:

```
container_name|contrib_raw_names|year                                        64064559
unstructured                                                                 61711602
container_name|contrib_raw_names|volume|year                                 49701699
container_name|contrib_raw_names|unstructured|volume|year                    36401044
container_name|contrib_raw_names|unstructured|year                           26663422
contrib_raw_names|unstructured                                               16731608
container_name|contrib_raw_names|doi|unstructured|year                       14207167
container_name|contrib_raw_names|doi|year                                    13159340
```

Some examples:

```
{
  "biblio": {
    "container_name": "Intern. J. Comput. Math.",
    "contrib_raw_names": [
      "D. Levin"
    ],
    "volume": "B3",
    "year": 1973
  },
  "index": 19,
  "key": "PhysRevB.48.6913Cc15R1",
  "ref_source": "crossref",
  "release_year": 1993,
  "release_ident": "i6s6e64n55hh5oned32mdwrs2i",
  "work_ident": "aaaeuvgitzfafczctw3bseauri"
}
```

This refers to:

* https://www.tandfonline.com/doi/abs/10.1080/00207167308803075
* 1972, and not 1973, 1993
* https://fatcat.wiki/release/3cstmufhszalvpnppwxjohnnsa

It would help to go from "container name" to "issn", e.g. here: 0020-7160

* https://fatcat.wiki/release/search?q=levin+container_id%3A%22y4k3i2fvabgarkvywismzvy23a%22+year%3A1972

```
$ grep -i "Intern.*J.*Comput.*Math.*" jabbrev.json
{"name": "COMPEL-THE INTERNATIONAL JOURNAL FOR COMPUTATION AND MATHEMATICS IN ELECTRICAL AND ELECTRONIC ENGINEERING", "abbrev": "COMPEL"}
{"name": "INTERNATIONAL JOURNAL OF APPLIED MATHEMATICS AND COMPUTER SCIENCE", "abbrev": "INT J APPL MATH COMP"}
{"name": "INTERNATIONAL JOURNAL OF COMPUTER MATHEMATICS", "abbrev": "INT J COMPUT MATH"}
```

Lookup name in issn:


```
$ zstdcat tmp/data.ndj.zst | grep -i "INTERNATIONAL JOURNAL OF COMPUTER MATHEMATICS" | jq .

  "@graph": [
    {
      "@id": "http://id.loc.gov/vocabulary/countries/enk",
      "label": "England"
    },
    {
      "@id": "organization/ISSNCenter#_1",
      "@type": "http://schema.org/Organization"
    },
    {
      "@id": "resource/ISSN-L/0020-7160",
      "identifiedBy": "resource/ISSN/0020-7160#ISSN-L"
    },
    {
      "@id": "resource/ISSN/0020-7160",
      "@type": [
        "http://id.loc.gov/ontologies/bibframe/Instance",
        "http://id.loc.gov/ontologies/bibframe/Work",

      ],
      "format": "vocabularies/medium#Print",
      "http://purl.org/ontology/bibo/issn": "0020-7160",
      "identifiedBy": [
        "resource/ISSN/0020-7160#ISSN-L",
        "resource/ISSN/0020-7160#ISSN",
        "resource/ISSN/0020-7160#KeyTitle"
      ],
```

We would need:

* rough abbrev name -> full name (jabbrev) -> issn (issnlister) -> container id (fatcat)

Example, title match with OL:

```
{
  "biblio": {
    "container_name": "Private schooling in less economically developed countries",
    "contrib_raw_names": [
      "Caddell M."
    ],

  "index": 7,
  "key": "CIT0008",
  "ref_source": "crossref",

  "release_ident": "xqgaanhpf5gotdxxxytgyxw2ty",
  "work_ident": "aaaq35j3angwzdpzcvzdil3v4y"
}
```

In the PDF, we find a DOI as well, but it seems to be not extracted. In fact;
the ref data comes from crossref.

Grobid gets the DOI:
