Ticket:

Current Situation:

• This metric is tracked in Wikidata and Wikibase Suite.
• In Wikibase Suite, the number of entities is tracked via SPARQL queries, meaning that we can only collect this metric for instances with SPARQL endpoints configured and accessible.
• The logic used to calculate this metric is not currently documented or aligned across teams.

Goal:

• Confirm and document the current method used by Wikibase Suite to track the number of entities.
• Clearly communicate to the PM how the metric is derived, including constraints (e.g. limited to SPARQL-enabled instances).
• Provide enough detail so this logic can be shared across the Wikibase ecosystem for transparency and alignment.

Acceptance Criteria:

• Confirm that the number of entities is currently tracked through SPARQL queries in the wbs meta data pipeline.
• Document the exact SPARQL query or logic used to calculate this metric.
• Note the scope limitation: metric only applies to instances with accessible SPARQL endpoints.
• Share the documentation with the PM in a way that is suitable for reuse across Cloud and Wikidata teams.
• Flag any relevant assumptions or edge cases (e.g. entity types included or excluded).

Notes:

• This metric gives a partial but valuable view of content size within the ecosystem.
• Transparency about scope and method will help build confidence in the metric even if it's not comprehensive.
