This looks similar to React application frameworks like react-admin [1] or Refine [2]:

    const App = () => (
      <Admin dataProvider={dataProvider}>
         <Resource name="posts" list={PostList} />
      </Admin>
    )
    
    const PostList = () => (
      <List>
        <DataTable>
          <DataTable.Col source="date" />
          <DataTable.Col source="title />
          <DataTable.Col source="author" />
        </DataTable>
      </List>
    );

The article mentions XML, but the true revolution is JSX itself, which lets you describe any piece of logic as a React element. This opens the possibility to create DSL for everything, just like in Python.
