Best strategy to add new items derived from PM20?

edit
Latest comment: 5 years ago3 comments1 person in discussion
  1. Producing all available properties in one script,
    (current implementation for companies with type/official-name/incepted/abandoned/gnd-id in companies_missing_in_wikidata.rq (also restricts result to entries checked with Mix-and-match) and script create_missing_wikidata.pl)
  2. or alternatively, adding items with a
    1. very basic query/script covering only label(s), perhaps description(s), type and pm20 id,
    2. complemented by many queries/scripts, which will add a single property for all linked items (already existing or created from PM20) lacking that property.
    (example implementation for organization type (P31) in missing_class_via_pm20.rq)

The second strategy requires more queries/scripts, more invocations and better documentation. However, it allows for progressive improvement (e.g., incrementally mapping more and more professions). Additionally, it can be combined with manual addition of items (e.g., via mix-n-match), where also very few properties are populated automatically.

Implementation: One script, multiple queries, multiple invocations for enhancement
One script (add_missing_wikidata.pl), which can be called in 'create' or 'enhance' mode. For item creation, it uses a query such as persons_missing_in_wikidata.rq. For enhancing Wikidata one property at a time, the script uses either a generic query (property_missing_in_wikidata.rq - works, if the source property can be addressed directly or via a property path), or a configuratble property-specific query.

Script invocation with add_missing_wikidata.pl pm20_pe enhance P227 and running the line below in QS adds GND ID to Georges Ibrahim Abdallah (Q3102918):
