# Metadata Database for Danbooru2023 |
|
Danbooru 2023 datasets: https://huggingface.co/datasets/nyanko7/danbooru2023 |
|
|
|
This dataset contains a sqlite db file which have all the tags and posts metadata in it.<br> |
|
The Peewee ORM config file is provided too, plz check it for more information. (Especially on how I link posts and tags together) |
|
|
|
The original data is from the official dump of the posts info.<br> |
|
Check this [link](https://console.cloud.google.com/storage/browser/danbooru_public/data) for more info. |

## Details |
|
This section contains some details that you need to be aware of if you want to use other ORM system or use plain SQL query to utilize this database. |
|
|
|
#### Custom Enum Fields |
|
Some fields in Post/Tags use my custom enum field to store type/category or something like that: |
|
|
|
* Post.rating |
|
* 0: general |
|
* 1: sensitive |
|
* 2: questionable |
|
* 3: explicit |
|
* Tag.type |
|
* 0: general |
|
* 1: artist |
|
* 2: character |
|
* 3: copyright |
|
* 4: meta |
|
|
|
#### Tag List |
|
I use peewee ManyToManyField to implement the Tag List things. Which utilize a through model which have all the pair of Tag and Post<br> |
|
Since it is very likely we will want to use Tag to query posts, so many-to-many is better.<br> |
|
The con of this design is the database file will be 1.5x larger than before(we have 0.25B entries for the post-tag pairs), but the query speed become 2~3x faster, so I think it is acceptable. |
|
|
|
After done some checking, I can ensure that all the "categorical tag list" can be done by full list + filter, and that is how I done it now. Check the db.py for more details. |
|
|
|
|
|
#### Utils |
|
if you think above details are too complicated, just use the db_utils.py and other PeeWee API to utilize this database. |
|
I also provide a write_csv.py for exporting whole dataset into csv for data analysis. |

Note: I have changed the definition of TagListField and have added some index into it. Do not mixed up the .db files from 2 different repo. |
