Show Dataset Access Counts and Popularity in UI

We’ve pushed an update to the API and UI to read the access log from IPFS (5413e10).

It’s important to note that this is not a download count, but an integrity verification counter, that is, the number of times the Verify Integrity button has been clicked for a given dataset. There’s a new badge on the dataset details page that shows this count, and it’s aggressively cached with a 1-hour TTL to avoid issues with IPFS-derived latency:

We need a way to provide an asset object popularity metric backed by the Trust Service / IOTA flow.

Actual downloads cannot currently be measured by Trust Service, because downloads happen via presigned object-storage URLs and the file transfer bypasses Trust Service. Also, we cannot extend the Trust Service API for this task.

Proposal: When the Platform API generates a presigned download URL for an asset object, also trigger an existing Trust Service proof-read request for that object. This will create a Trust-side logged event that we can use as a popularity proxy.

Important note: This is not a precise download count. It measures download intent / authorization, not confirmed completed transfers.

Commit 633b796 introduces an update to count “download intents” as well as integrity checks, all backed by the IOTA DLT. It’s a bit cumbersome, but it fits the original intent.
