Overview

Package update provides methods for common update operations for SFO Museum Who's On First records. Methods signatures may still change.

Functions

func CreateWithFeature

func CreateWithFeature(ctx context.Context, r reader.Reader, wr writer.Writer, tmp_f *geojson.Feature, parent_id int64, extra_props map[string]interface{}) (int64, error)

Create a new Who's On First record and write it to 'wr'. The signature for this method is a bit of a mess right now and reflects the specific concerns of the go-sfomuseum-gis/cmd/sfo-export-complex tool where it was first written. 'tmp_f' is assumed to be a GeoJSON records that was exported from the SFO GIS system so we are mostly only concerned with its geometry and a handful of properties. Which is another way of saying 'tmp_f' is assumed to contain a bunch of ESRI-specific properties we don't want to export. 'parent_id' is passed in explicitly in order to append its hierarchy using 'r' to load the parent feature. 'extra_props' are things that used to set explicitly or passed in as atomic values namely wof:repo and edtf:inception.

func ReplaceWithFeature

func ReplaceWithFeature(ctx context.Context, r reader.Reader, wr writer.Writer, tmp_f *geojson.Feature, old_id int64, new_parent_id int64, date string) (int64, error)

Replace (or superseded) a new Who's On First record from a geojson.Feature instance and write it to 'wr'. See notes about method signatures in the ReplaceWithSelf method.

func ReplaceWithSelf

func ReplaceWithSelf(ctx context.Context, r reader.Reader, wr writer.Writer, old_id int64, new_parent_id int64, date string) (int64, error)

Replace (or superseded) a new Who's On First record and write it to 'wr'. The signature for this method is a bit of a mess right now and reflects the specific concerns of the go-sfomuseum-gis/cmd/sfo-export-complex tool where it was first written. This method shares many of the same concerns as CreateWithFeature and the two methods should, where possible, be reconciled.
