···22[records](https://atproto.com/guides/glossary#record) in the
33user's [repo](https://atproto.com/guides/glossary#data-repo) on the
44[PDS](https://atproto.com/guides/glossary#pds-personal-data-server). These are stored as key/values in the user's repo
55-divided by [collections](https://atproto.com/guides/glossary#collection). The API shows them as JSON via the api. Like
66-this
77-record of a Bluesky "like"
55+grouped by [collections](https://atproto.com/guides/glossary#collection).
66+77+You can get records from a PDS as JSON, like this Bluesky "like" record:

···2121posts, [tangled](https://tangled.org/) repos,
2222[standard.site](https://standard.site/) docs, everything like that is stored publicly on your repo as an atproto record.
23232424-The records are stored in collections and have record keys. This is usually expressed by an at-uri like
2525-`at://did:plc:rnpkyqnmsw4ipey6eotbdnnf/app.bsky.feed.like/3mhbs2cnrl22r`.
2424+The records are stored in collections and have "record keys", sometimes called rkeys. By combining them with the author's identity, they can form an `at-uri` like this:
2525+2626+```
2727+at://did:plc:rnpkyqnmsw4ipey6eotbdnnf/app.bsky.feed.like/3mhbs2cnrl22r
2828+```
26292730This uri can be broken down into 3 parts:
28312929-- `at://did:plc:rnpkyqnmsw4ipey6eotbdnnf` is the DID of the user
3232+- `at://did:plc:rnpkyqnmsw4ipey6eotbdnnf` is the `DID` of the user
3033- `app.bsky.feed.like` is the collection
3134- `3mhbs2cnrl22r` is the record key
32353333-You will also notice that the record has a `$type` field, `app.bsky.feed.like` for the above record. This is
3434-the [lexicon schema](https://atproto.com/specs/lexicon) for the record. There will be more on this later, but for now
3535-it's important to know it's a [NSID](https://atproto.com/guides/glossary#nsid-namespaced-id) of the atproto app and
3636-shows how the record should look.
3636+You might also notice a `$type` field in the record, set to `app.bsky.feed.like` in the example above, matching its collection. More on [this later](https://atproto.com/specs/lexicon).
