General

 * Same WP/WD tags on relation and on member ways
 * Same WP/WD tags on relation and on member nodes. For example, the relation with the city boundary and city center node has the same tag as the center node.
 * Same WP/WD tags on relation and on super relations

Rivers

 * a river could consist of multiple relations (multipolygon water and waterways) and simple ways

Maritime borders

 * Some objects have both maritime and coastal borders. Which should have WP/WD tags?

Data quality benefits

 * Get all Wikipedia links in all languages for a given object
 * In case a Wikipedia article is renamed or deleted, Wikidata is more likely to stay intact. It will link to other languages or simply provide a placeholder for the future articles.
 * Easier to validate Wikipedia links, e.g. detect that link points to a disambiguation page instead of a place page when the original wiki page got renamed
 * Easier to validate administrative boundaries and admini_levels, to see that both Wikidata and OSM area hierarchy matches


 * Add multilingual names to any OSM objects

Usage benefits

 * Wikipedia can show object outline in various articles based on Wikidata ID
