# Bluesky Aozora Dive

... Is an archive of atproto's firehose (and relatedly bluesky) streams.

This dataset name is inspired from a [song](https://www.uta-net.com/song/295599/).

## Data Formats

We present data as is with minimum enrichment.

- Likes authors are enriched with their author and usernames. The post themselves are not enriched since that will incur additional requests which can be quite heavy.
- Any cryptographic CIDs are stripped as they do not possess any useful textual data.

### Streams

The firehose is split into 2 jsonl file for your usage:

- `..._atproto_interactions.jsonl`: Contains interaction events, such as likes, follows, reposts and blocks
- `..._atproto_general.jsonl`: Contains accounts, identities, posts and replies

### Common Fields

- `typ`: Represents the data **typ**e. 
- `usr`: Which **Us**e**r** is it from. Represented in the `Usernames` format below.
- `rid`: Record Key. Use this to access data from bsky api.

The most basic root construct will typically contain:

```json
{
    "typ": "<Type>",
    "usr": {
        "did": "did:plc:ssd5xwqvrdrxyu2br7sfjwzy",
        "nms": "samera1989.bsky.social"
    },
}
```

Usernames are constructed in the following format:

```json
{
    "did": "did:plc:4hqjfn7m6n5hno3doamuhgef",
    "nms": "yui.syui.ai"
}
```

`did`: `Decentralized ID`. Consider this as `ID` for most cases and it points to a unique ID.  
`uns`: `Usernames`. Either can be a string or a list of strings. Do not blindly assume this is going to be only a string! Though generally, it should just be a string.

For most cases, expect these 2 fields to describe a user.

### Blobs

Blobs represent media content. Typically you can tell it's a blob if it has a `mime` field and a `cid`.

```json
{
    "mime": "image/jpeg",
    "size": 891965,
    "cid": "bafkreifu35fvx45eyldhpoyb3zgtb5dobvjfpw5kkeexwxefrfpzye2pji"
}
```

Given the user account is this:
```json
{
    "typ": "account",
    "usr": {
        "did": "did:plc:lri5xcv6ogaldxkigm32wa57",
        "nms": "yukichiroyuchi.bsky.social",
        "avy": {
            "mime": "image/jpeg",
            "size": 226086,
            "cid": "bafkreif3z2y2rfrfcjt4rwwps4ib7q7qywrdt76bw6dmj5ebqefgllpima"
        },
        "bnr": null,
        "crt": 1723726663.57,
        "dsc": "――あなたの日常に、AIの籠った音色を。\n\n▼思い出や日常、希望をお聞かせください。その想いを曲にいたします。\nhttps://forms.gle/rF2iqwXxabfVEifd7",
        "dsp": "雪白ゆっち feat.AI Creator"
    }
}
```

Construct the avy url like so:

Template: `https://bsky.social/xrpc/com.atproto.sync.getBlob?did=<usr.did>&cid=<usr.avy.cid>`

A full link looks like this: `https://bsky.social/xrpc/com.atproto.sync.getBlob?did=did:plc:lri5xcv6ogaldxkigm32wa57&cid=bafkreif3z2y2rfrfcjt4rwwps4ib7q7qywrdt76bw6dmj5ebqefgllpima`

Yes I did spend a while trying to lookup to see why it is not working.

### Posts (Simple)

Posts can get rather complicated. Here's a sample of a simple post.

```json
{
    "typ": "post",
    "usr": {
        "did": "did:plc:ssd5xwqvrdrxyu2br7sfjwzy",
        "nms": "samera1989.bsky.social"
    },
    "rid": "3kzyon77od52v",
    "chg": "create",
    "tst": 1723987630.494,
    "pst": {
        "txt": "✔✔✔On Aug 18, 2024, 11:59 AM(UTC). According to Binance Market Data, Bitcoin has crossed the 60,000 USDT benchmark and is now trading at 60,006.578125 USDT, with a narrowed 1.49% increase in 24 hours.👀👀",
        "emb": null,
        "fct": [],
        "lbl": [],
        "lng": [],
        "tgs": [],
        "rpl": null
    }
}
```

- `tst`: Contains the timestamp in unix float time.
- `chg`: Change type. Typically either `create` or `delete` for posts. `change` for allowing Direct Messages.
- `rid`: Record Key. Use this to access data from bsky api.
- `pst`: Contains the actual posted data.

### Posts (Complex)

As for replies and other fields, here's a more complex example.

```json
{
    "typ": "reply",
    "usr": {
        "did": "did:plc:4hqjfn7m6n5hno3doamuhgef",
        "nms": "yui.syui.ai"
    },
    "rid": "3kzyotm2hzq2d",
    "chg": "create",
    "tst": 1723987844.937,
    "pst": {
        "txt": "https://card.syui.ai/baiser \nbaiser\njoin : baiser.blue [IIT]\nten : 1000\naiten : 21037247\n---\n[1-7]\nten d : shuffle[IIT☑]\nten p : post\n---\n",
        "emb": null,
        "fct": [
            {
                "typ": "@",
                "val": "https://card.syui.ai/baiser",
                "rng": [
                    0,
                    27
                ]
            }
        ],
        "lbl": [],
        "lng": [],
        "tgs": [],
        "rpl": {
            "typ": "post",
            "usr": {
                "did": "did:plc:vok247eewjmbmo3kxaizct2i",
                "nms": "baiser.blue"
            },
            "rid": "3kzyotbooo22c",
            "rrt": {
                "typ": "post",
                "usr": {
                    "did": "did:plc:vok247eewjmbmo3kxaizct2i",
                    "nms": "baiser.blue"
                },
                "rid": "3kzyosf6atg2v"
            }
        }
    }
}
```

- `fct`: Stands for Facets:
  - `typ`: The facet type. (`tag`,`link`,`mention`)
  - `val`: The facet value. Note that this can be a `Username` dict when `typ` == `mention`
  - `rng`: Byte range. AFAIK this is in UTF-16 but I can be wrong. Follow atproto's docs for this.
- `lbl`: Labels. A list of strings. Though typically empty list for firehose streams. Labels are sent seperately firehose stream-wise.
- `lng`: Languages. Either an list (Can be empty) or a string.
- `tgs`: "Additional hashtags, in addition to any included in post text and facets."
`rpl`: The post that the current post is replying to.
  - *Note:* The reply post is not enriched with the actual post.
  - `typ`/`usr`/`rid`: [Refer to the simple posts section.](#posts-simple)
  - `rrt`: Root post. Can be `null` if root post is the same as the `rpl` post `rid`.

### Accounts

```json
{
    "typ": "account",
    "usr": {
        "did": "did:plc:cj3ngde5wbljf5sh33g7zsdz",
        "nms": "shirotsu.bsky.social",
        "avy": {
            "mime": "image/jpeg",
            "size": 79776,
            "cid": "bafkreiczz2spptgturm43r33impbkcar4tmdmnh34pqkp2tynlztbxmw7a"
        },
        "bnr": {
            "mime": "image/jpeg",
            "size": 748930,
            "cid": "bafkreigb5l3u32quxzhpbca6bnrunfdau3m4bp6fdntmj2lwec3erkssty"
        },
        "crt": null,
        "dsc": "こっちでは、主に練習中の下手なイラスト・ゲーム関系とかを投稿していきたいな〜\n\n最推しのねくろさんの配信を見るといやされる( ◠‿◠ )",
        "dsp": "しろっつ🖤🐐👑"
    }
}
```

For Accounts, the `usr` field is more filled. In addition to `did` and `nms`, there are other fields like:

- `avy`/`bnr`: either a `Blob` or null. Refer to [Blobs](#blobs) section above.
- `crt`: Account Creation time. Can be null!
- `dsc`: Profile Bio / Blurb Section.
- `dsp`: Display name.

### Reconstructing to a AtUri

For `post` and `reply` types, Take the following values and combine them into the following url:

`at://<usr.did>/app.bsky.feed.post/<rid>`

Replies are just posts.

For `repost` and `like` types, it's similar but a bit different:

- Reposts: `at://<usr.did>/app.bsky.feed.repost/<rid>`
- likes: `at://<usr.did>/app.bsky.feed.like/<rid>`

### Enrichment of replies

```
curl -L -X GET 'https://public.api.bsky.app/xrpc/app.bsky.feed.getPosts?uris=at://did:plc:4hqjfn7m6n5hno3doamuhgef/app.bsky.feed.post/3kzyotm2hzq2d' \
-H 'Accept: application/json' \
-H 'Authorization: Bearer <TOKEN>'
```

### Illegal Spec Followers

In other words, we also capture content that failed to follow specs. Like this:

```json
{
    "typ": "IllegalSpecFollowerAkaFixYourShit",
    "record": {
        "text": "任某（男，31歲），被行拘！ ",
        "$type": "app.bsky.feed.post",
        "embed": {
            "uri": "https://www.headline01.com/a/Xio3zSUuGvX7J1jCSG_F5g-51479340.html",
            "$type": "app.bsky.embed.external#main",
            "external": {
                "uri": "https://www.headline01.com/a/Xio3zSUuGvX7J1jCSG_F5g-51479340.html",
                "thumb": {
                    "ref": "bafkreidrfrfluqo26yy4pemkcpgug2p5sea3xrwh3schfnns5owa7gbwvm",
                    "size": 86924,
                    "$type": "blob",
                    "mimeType": "image/jpeg"
                },
                "title": "任某（男，31歲），被行拘！",
                "description": ""
            }
        },
        "createdAt": "2024-08-18T14:05:19.645644Z"
    }
}
```
 
Lines marked as `IllegalSpecFollowerAkaFixYourShit` should be ignored in general though. Content isn't great anyway.

## Various Notes

### Recommendations

For getting a more proper stream of posts, it's recommended to keep a track of users + posts in a index cache.

Then again, you can just fetch a list from bsky api directly lol.

Do consider reading up on bsky docs and atproto docs.

### Docs Nonsense

When the bluesky docs say: "...Implemented by PDS".

You should probably use the following base url: `https://bsky.social/xrpc/`

### Deletions

UnActions ("unpost","unlike","unrepost") only contains `rid` as the record key.

### License

For everyone out there, data is meant to be free unlike some previous license I did. This is free for grabs aka `CC-BY-4.0`.

for Big Corps wanting to use it: Sure. As long as you cite this dataset + `CC-BY-4.0` license. Be nice to people who have came before you and did it.

### Citations

We would much love academia to cite this dataset. Be nice please `:)`
