Apache Arrow
This is the page you're already on — the Human View toggle above shows it in full.
A green key on the record, left, is one Decision Insights added. It doesn't exist on the company's site or in a wire feed. The same key labels its row on the right, so you can match them directly. More on how DI enriches a record.
The record
This is what the machine sees: the exact JSON-LD an agent receives for this listing.

What we add
Topic graph
A wire service tags a release with a category, once. It doesn't maintain a durable graph over time. We connect them to a topic graph an agent can query.
Data Center https://decisioninsights.ai/term/data-center/
Storage https://decisioninsights.ai/term/sd-storage/
Central Processing Unit https://decisioninsights.ai/term/central-processing-unit-cpu/
and 3 more
Counted facts
A protocol or open source project keeps no vendor list and publishes no figures of its own to check this against. This counts how it actually shows up across the graph -- articles that name it, the organizations named alongside it in those articles, similar projects, and organizations whose topic tags overlap with its own -- computed, not curated.
