For the most part, a JSONLD Dataset Proxy has parity with JavaScript Object Literals. However, there are a few differences to highlight. This section details how you would do different tasks.
For the most part, you can think of a JSONLD Dataset Proxy as a JavaScript Object Literal with "Sets" instead of arrays.
### Defining a Context and Type
The first step to getting a JSONLD Dataset Proxy is defining the JSONLD Context and TypeScript Typings. This can either be done through a [generator](https://github.com/o-development/shexj2typeandcontext) or defining them manually.
The first step to getting a JSONLD Dataset Proxy is defining the JSONLD Context and TypeScript Typings. This can either be done through a [generator](https://ldo.js.org/latest/api/cli/build/) or defining them manually.
In this example typescript typing `IPerson` is an interface that represents a person. Notice the `@id` and `@context` fields. Be sure to include them in your interfaces if you wish to use those properties.
```typescript
import { ContextDefinition } from "jsonld";
import { LdoJsonldContext, LdSet } from "@ldo/jsonld-dataset-proxy";
interface IPerson {
"@id"?: string;
"@context"?: ContextDefinition;
name?: string[];
"@context"?: LdoJsonldContext;
name?: LdSet<string>;
age?: number;
bestFriend?: IPerson;
knows?: IPerson[];

}

### Deleting an Entire Object
If you want to delete all triples represented by an object, there are two ways using the `delete` operator.
First, you can call `delete` on a specific property:
```typescript
const dataset = await serializedToDataset(`

@prefix foaf: <http://xmlns.com/foaf/0.1/> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

foaf:bestFriend example:Person2.

`);

delete person.bestFriend;
console.log(dataset.toString());
// <http://example.com/Person1> <http://xmlns.com/foaf/0.1/name> "Alice" .
```
If you want to delete all triples represented by an object you can call `delete` on the `@id` property.

If you already have generated ShapeTypes, you may install the `@ldo/ldo` library independently.
```

Below is a simple example of LDO in a real use-case (changing the name on a Solid Pod). Assume that a ShapeType was previously generated and placed at `./.ldo/foafProfile.shapeTypes`.
```typescript
import { parseRdf, startTransaction, toSparqlUpdate, toTurtle } from "@ldo/ldo";
import {
parseRdf,
startTransaction,

set,
} from "@ldo/ldo";

janeProfile.name = "Jane Smith";
