Apache DataSketches

Human View Machine View

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/ Big Data https://decisioninsights.ai/term/big-data/ IT Governance https://decisioninsights.ai/term/it-governance/ and 5 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.
