Compared evidence

Synthesis

What changed

The original homepage evidence suggested Data.gov is a broad open-data portal with a catalog link and dataset count. The follow-up evidence strengthened that by confirming the catalog is the main search/browse interface and that a separate metrics dashboard exists, both repeating the same dataset total.

Confirmed

Data.gov is presented as an official U.S. government site.
The portal’s dataset catalog is at https://catalog.data.gov/.
The catalog and homepage both report 604,965 datasets available on Data.gov.
The catalog supports search, filters, and sorting for dataset discovery.
The metrics page exists and includes metrics by organization.

Still uncertain

Whether the dataset count is current beyond the snapshot times in the retrieved pages.
What specific metrics are shown on the Data.gov metrics dashboard beyond the visible excerpt.
The full contents and structure of the highlighted dataset pages and organization pages, since they were not visited.

It is the top highlighted dataset on the catalog homepage and likely contains the most directly relevant detailed metadata from the explored pages.

Not established

Uncertainties

The record does not include the full page DOM, so additional homepage sections and linked destinations are not verified.
Candidate links were not visited, so their current contents and relevance are unknown.
The dataset count is a snapshot from the retrieved page and may change over time.

Source boundaries

Provenance

The original source and each successfully retrieved follow-up remain separate. Candidate and suggested links are not represented as visited evidence.
