API for Sticky meta. Allows attaching arbitrary metadata on custom entities. Can be applied to a column of entities based on semtype or column tags.
See samples: https://public.datagrok.ai/js/samples/dapi/sticky-meta-tags
Example
var schema = await dapi.stickyMeta.createSchema('test-schema', {name: 'molecule', matchBy: 'semtype=molecule'}, {name: 'prop', type: 'string'});
var metadata = await dapi.stickyMeta.getAllValues(schema, DG.Column.fromList('string', 'key', ['h2o']));
