OpenAtlas

Idea:
create a generic import functionality that imports all kind of data with their relation from discipline specific CSV templates into openatlas

Prerequisite:
discuss structure of generic import functionality

Stefan's approach:
1. Fill in thanados specific template like this one
https://docs.google.com/spreadsheets/d/1IIPGKvSRNi6Qeir6070VS4u7uvHdlpYenEhRkCaGJcI/edit?usp=sharing
2. Get the data as CSV to OpenAtlas
3. Map the CSV to the generic import format (Name, Alias, Geometry, Types, Dates, Reference Systems etc.)
4. Witchcraft and Magic -> all is imported to OpenAtlas

• Alias* ✅
• Geometry as WKT* ✅
• Existing External Reference System with ID including identifier* ✅
• Value types* ✅
• Administrative Unit* ✅
• Historical Place* ✅
• Existing References with ID including page number -> #2244
• OpenAtlas Class name to know which level the place is -> #2244
• Parent import ID -> #2244
  (* These will be added to all import options)

• Better warnings (showing where warning appears)✅
• Remove no cover by manipulating CSV in tests ✅
• What if duplicate reference systems are given ✅
• Handle error if multiple type ids from the same single type ✅
• Translations ✅
• Manual entry ✅
