These extensions are recognized by the neonto language services. Editor features vary by format.

File extension(s)	Language id	Notes

.yarrrml, .yarrrml.yml, .yarrrml.yaml	yaml	YAML editing plus neonto's YARRRML-specific completion and diagnostics, with dedicated file icons.

RDF serializations accepted for data sources

When adding a local or remote RDF file as a data source, the following serializations are accepted:

Serialization	Typical extensions

Size limits

• neonto.langServer.maxFileSize (default 256 MB) — files larger than this are not indexed, so their terms are unavailable for autocompletion, hover, or workspace-wide term resolution.
• neonto.langServer.liveDiagnosticsMaxFileSizeKb (default 1024 KB) — files larger than this skip live, on-type diagnostics; run neonto: Run SHACL Validation on demand instead.
