Examples from the readme file do not work.

[EnricoVogt]

The Example of the readme use CharsetType & Index which are not part of @v.1.0.0 ("https://deno.land/x/dso@v1.0.0/mod.ts").
It should be

import {
  BaseModel,
  Defaults,
  dso,
  Field,
  FieldType,
  CharsetType,
  Index,
  IndexType,
  Join,
  Model,
  Where
} from "https://raw.githubusercontent.com/manyuanrong/dso/master/mod.ts";

instead of

import {
  BaseModel,
  Defaults,
  dso,
  Field,
  FieldType,
  CharsetType,
  Index,
  IndexType,
  Join,
  Model,
  Where
} from "https://deno.land/x/dso@v1.0.0/mod.ts";
