# Neum Vector

> Data interface for `Neum Vector`

The `NeumVector` is the object used to organize data extracted for a given data source. It is analogous to similar constructs (i.e. `Document`) used in frameworks like Langchain and LlamaIndex.

The goal of this interface is to abstract three properties:

* `id` (str): This is a unique identifier for a given vector. The id is constructed throughout the pre-processing of the data and used as the vector id within the vector database. It is used at synchronization to ensure vectors are not being re-computed and duplicated.
* `vector` (List\[float]): Vector embedding generated from the content in the `NeumDocument`.
* `metadata` (dict): This value contains the attached metadata for a given document. This can include values extracted from the data source or loader, as well as any calculated values. Metadata includes the `content` from the `NeumDocument`.

## Usage

```python NeumVector
from neumai.Shared.NeumVector import NeumVector
neum_vector = NeumVector(
    id = 'abc', 
    vector = [.....],
    metadata = {'text':'Hello', 'createdDate':'2023-01-01'}
)
```
