# Add Joplin document loader [Joplin](https://joplinapp.org/) is an open source note-taking app. Joplin has a [REST API](https://joplinapp.org/api/references/rest_api/) for accessing its local database. The proposed `JoplinLoader` uses the API to retrieve all notes in the database and their metadata. Joplin needs to be installed and running locally, and an access token is required. - The PR includes an integration test. - The PR includes an example notebook. --------- Co-authored-by: Dev 2049 <dev.dev2049@gmail.com>

Document Loaders
|
|
==========================

|
|
|
.. note::

`Conceptual Guide <https://docs.langchain.com/docs/components/indexing/document-loaders>`_
|
|
|
|
|
|
Combining language models with your own text data is a powerful way to differentiate them.
|
|
The first step in doing this is to load the data into "Documents" - a fancy way of say some pieces of text.
|
|
The document loader is aimed at making this easy.
|
|
|
|
|
|
The following document loaders are provided:
|
|
|

|
Transform loaders
|
|
------------------------------
|
|
|
|
These **transform** loaders transform data from a specific format into the Document format.
|
|
For example, there are **transformers** for CSV and SQL.
|
|
Mostly, these loaders input data from files but sometime from URLs.
|
|
|
|
A primary driver of a lot of these transformers is the `Unstructured <https://github.com/Unstructured-IO/unstructured>`_ python package.
|
|
This package transforms many types of files - text, powerpoint, images, html, pdf, etc - into text data.
|
|
|
|
For detailed instructions on how to get set up with Unstructured, see installation guidelines `here <https://github.com/Unstructured-IO/unstructured#coffee-getting-started>`_.

Public dataset or service loaders
|
|
----------------------------------
|
|
These datasets and sources are created for public domain and we use queries to search there
|
|
and download necessary documents.
|
|
For example, **Hacker News** service.
|
|
|
|
We don't need any access permissions to these datasets and services.

Proprietary dataset or service loaders
|
|
------------------------------
|
|
These datasets and services are not from the public domain.
|
|
These loaders mostly transform data from specific formats of applications or cloud services,
|
|
for example **Google Drive**.
|
|
|
|
We need access tokens and sometime other parameters to get access to these datasets and services.
