=== Fetch data
There are IETF datasets that can be converted into RelatonXML/BibXML/BibYAML formats:
- `ietf-rfcsubseries` - https://www.rfc-editor.org/rfc-index.xml (`<bcp-entry>`, `<fyi-entry>`, `<std-entry>`)
- `ietf-internet-drafts` - convert files from local directory `./bibxml-ids`. Use `rsync -avcizxL rsync.ietf.org::bibxml-ids ./bibxml-ids` command to fetch the files.
- `ietf-rfc-entries` - https://www.rfc-editor.org/rfc-index.xml (`<rfc-entry>`)
The method `RelatonIetf::DataFetcher.fetch(source, output: "data", format: "yaml")` converts all the documents from the dataset and saves them to the `./data` folder in YAML format.
Arguments:
- `source` - dataset name (`ietf-rfcsubseries` or `ietf-internet-drafts`)
- `output` - folder to save documents (default './data').
- `format` - the format in which the documents are saved. Possible formats are: `yaml`, `xml`, `bibxml` (default `yaml`).
