# Daletl specification for Dalet v1.0-preview
## Data format
## Daletl
Daletl is data representation for Dalet interfaces. [DaletPack](./daletpack.md) serializes/deserializes into Daletl.
Daletl must be serialized as [DaletPack](./daletpack.md). All data transfer between server and client is done in this format.
### Root
Daletl root is array of tags. For convenience, we will use the json5 representation of the data.
Daletl root is array of tags. For convenience, we will use the typescript notation.
```json5
[]
```typescript
type Root = Tag[];
```
### Tag
All tags specification is in [Tags](./tags.md).
Each tag may be one of four types:
#### Data Representation
##### As array of 1-3 elements
1. Tag id
2. Tag body (optional if argument is null)
3. Tag argument (optional)
Tag id is integer number.
Body can be only a string, null, array of tags or tag (equals to array of tags with 1 tag).
Argument can be number or string.
###### Heading example
```json5
[1, "This is heading", 1]
```typescript
interface Tag {
id: number;
body: Tag[] | null;
argument: string | number | null;
}
```
###### Unordered list example
### Example
```json5
[
4,
[
[0, "Item 1"],
[0, "Item 2"],
],
]
```
##### As string
String becomes element tag.
```json5
"Element"
```
equals to
```json5
[0, "Element"]
```
##### As array of tags
If array not started with a number. The implication is that this turns into an “element” tag
```json5
["Element", [1, "Heading"]]
```
equals to
```json5
[
0,
[
[0, "Element"],
[1, "Heading"],
],
]
```typescript
const root: Root = [
{
id: 1,
body: "I am Heading with level 1",
argument: 1,
},
];
```
