> `cag` is a Python Library offering an architectural framework to employ the build-annotate pattern when building Graphs.

---



[Official Documentation](https://cagraph.info/).

**Corpus Annotation Graph builder (CAG)**  is an *architectural framework* that employs the *build-and-annotate* pattern for creating a graph. CAG is built on top of [ArangoDB](https://www.arangodb.com) and its Python drivers ([PyArango](https://pyarango.readthedocs.io/en/latest/)). The *build-and-annotate* pattern consists of two phases (see Figure below): (1) data is collected from different sources (e.g., publication databases, online encyclopedias, news feeds, web portals, electronic libraries, repositories, media platforms) and preprocessed to build the core nodes, which we call *Objects of Interest*. The component responsible for this phase is the **Graph-Creator**. (2) Annotations are extracted from the OOIs, and corresponding annotation nodes are created and linked to the core nodes. The component dealing with this phase is the **Graph-Annotator**.

This framework aims to offer researchers a flexible but unified and reproducible way of organizing and maintaining their interlinked document collections in a Corpus Annotation Graph. 

## Installation

### Direct install via pip 

The package can also be installed directly via pip.
```
pip install cag
```

This will allow you to use the module **`cag`** from any python script locally. The two main packages are **`cag.framework`** and **`cag.view_wrapper`**.


### Manual cloning
Clone the repository, go to the root folder and then run:

```
pip install -e .
```
