gavo.protocols.vocabularies module¶

A shallow interface to IVOA vocabularies.

class gavo.protocols.vocabularies.SubjectMeta(content='', format='plain')[source]¶

A MetaValue translating UAT terms to their labels in HTML.

This follows the assumption that HTML is what humans look at, anything else is either computers or nerds.

gavo.protocols.vocabularies.download_file(url: str, cache: str, show_progress: bool, http_headers: Dict[str, str]) → str[source]¶

a partial implementation of astropy.utils.data.download_file to be used until we can rely on astropy 4.

We actually ignore cache and show_progress…

gavo.protocols.vocabularies.get_label(voc: Dict[str, Any], term: str) → str[source]¶: returns the label of term if it’s in the desise vocabulary voc, term capitalised otherwise.

gavo.protocols.vocabularies.get_vocabulary(voc_name: str, force_update: bool = False) → Dict[str, Any][source]¶

returns an IVOA vocabulary in its desise form.

See Vocabularies in the VO 2 to see what is inside of this.

This will use a cache to avoid repeated updates, but it will attempt to re-download if the cached copy is older than 6 months.

Use force_update to expire the cache immediately
