# refcat (wip)

Citation graph related tasks.

* compagnon project: [skate](https://git.archive.org/martin/cgraph/-/tree/master/skate)

Objective: Given data about
[releases](https://guide.fatcat.wiki/entity_release.html) and references derive
various artifacts, e.g.:

* a citation graph; nodes are releases and an edge is a citation (currently,
  this graph has about 50M nodes and 870M edges)
* a list of referenced entities, like ISSN (container), ISBN (book), URL
  (webpage), datasets (by URL, DOI, name, ...)

## Ongoing Notes

* [notes/version_0.md](version 0) (id only)
* [notes/version_1.md](version 1) (id plus title)
* [notes/version_2.md](version 2) (v1, full schema)
* [notes/version_3.md](version 3) (v2, unstructured)
* [notes/version_4.md](version 4) (v3, extra sources, qa)

## Deployment

We are testing a zipapp based deployment (20s for packaging into a 10MB zip
file, and copying to target).

Caveat: The development machine needs the same python version (e.g. 3.8) as the
target, e.g. for native dependencies. It is relatively easy to have multiple
versions of Python available with [pyenv](https://github.com/pyenv/pyenv).

```
$ make refcat.pyz && rsync -avP refcat.pyz user@host:/usr/local/bin
```

On the target you can call (first run will be slower, e.g. 4s, subsequent runs
at around 1s startup time).

```
$ refcat.pyz
