Server Basics
具体的完整定义见 ./server/api/models.py。
- Dataset：单个数据集单位。包含可选的坐标信息，用于在首页的地图上定位。DATASET_TYPE 包括：
class DatasetType(models.TextChoices):
RBR = 'RBR' # 来自 RBR 浮标的数据，如 OBS 浊度计的数据
NCF = 'NCF' # netCDF 格式数据，二维模型
RASTER = 'RT' # 光栅文件数据，要在地图上显示的数据
TABLE = 'TABLE' # 简单的表格数据
GENERAL = 'GNR' # 普通数据，不需要在地图上显示- VisFile：需要用来可视化的数据集。这些数据集可以在前端访问检索。VisFile 本身不包含时间范围，由其对应的 DataChannel 指定。其中，
first_dimension_name指定了了第一维度的名称，通常是时间。前端也会以这个维度为字段作为 x 轴。因此通常是 Time, DateTime, Date 等，视数据集体情况而定。FORMAT 包括：
class FileFormat(models.TextChoices):
RSK = 'rsk'
CSV = 'csv'
NCF = 'ncf'
TIFF = 'tiff'
OTHER = 'other'GeoReferencedType 包括：
class GeoreferencedType(models.TextChoices):
EMBEDDED = 'embedded' # 嵌入进文件的地理坐标信息
EXPLICIT = 'explicit' # 显示声明的地理坐标信息 （通过 longitude1, latitude1, longitude2, latitude2）
NONE = 'none' # 无地理坐标信息- DataChannel：和 VisFile 多对一。包括从 VisFile 内提取的数据频道及其单位、时间范围。由于大多数数据集都包含时间这一维度，因此将其写入了数据库，方便检索。
- RawFile：只提供下载，不提供可视化的文件。和 Dataset 多对一。如果该文件和 VisFile 相同，则和 VisFile 一对一，提供给前端下载链接。
- SiteUser：系统核心用户，为 Django 内 User 的扩充，增加了若干字段，和 User 一一对应。
需要注意的是，大多数实体除了 id 作为主键外，还有一个 uuid 作为检索键。外部的大多数 API 都使用 uuid 来检索而不是 id 来检索，而服务端内部使用 id 来进行查找、join 等操作。这是为了防止用户使用易猜到的序列 id 来随机访问数据。
Swagger 文档包括 API 的参数及各个参数的信息。
